    Halo Wars contains a lot of achievements, many of which are very challenging 
    or time consuming.  This guide will tell you how to get the achievements 
    associated with the Campaign and Skirmish modes as quickly and easily as 
    possible and give you a few tips for the others.  It also provides detailed 
    descriptions on how to find the skulls and black boxes.
    When I wrote the first version of this guide after owning this game for just 
    over a week, I had 800 gamerscore, while taking time to write this guide, 
    replaying missions to check strategies, and not playing much Matchmaking.  I 
    would recommend buying this game, but if you’re going to rent it, by following
    this guide you can easily get 700+ gamer score over a five day rental period 
    with moderate playing time.  If you’re looking for a particular achievement, 
    just use the Find function on your browser and type in the achievement’s name.
    All achievement names are listed in CAPS with the gamerscore amount in 
    parenthesis in the body of the guide.  
    This version (1.4) will be the final version of this guide, barring someone 
    making more DLC with achievements for this game.  I have recieved many 
    supportive messages regarding this faq and I'm glad to hear it has helped 
    people out.  I personally have all the achievements now except RUNNING THE 
    SHOW.  I will probably never go for it.  
    Please send a text (not voice) message to my Xbox Live account, ThermalStone, 
    if you have any questions or comments.

    I. Campaign: Mission by Mission Achievements, Skulls and Black Boxes. 
    This is not a complete walkthrough of each campaign mission, although I will 
    give tips on achievements and skulls that may include spoilers.  Unless noted 
    otherwise, I recommend that you look for both collectable items and try to get
    the achievement on your first playthrough of each mission.  I also recommend, 
    unless noted otherwise, that you play on Easy Difficulty.  As far as 
    achievements go, there is no difference between playing through on Easy or 
    Normal.  Achievements can also be earned with skulls turned on.  
    If you follow this guide, you’ll get the ALAS POOR ANDREW THOMAS (5) for 
    getting your first skull and GRAVEROBBER (30) for getting all the skulls.  
    Note that when you kill the required amount of enemies for a skull to appear a
    green circle showing the location of the skull will briefly flash on the mini 
    map.  Watch for it because it's easy to miss.
    If you follow this guide, you’ll also get the secret achievements.  When you 
    get the black boxes, you’ll unlock timeline events for HALO ACADEMIC (15) and 
    HALO HISTORIAN (40), although to get all the timeline events, you’ll need to 
    play skirmish as well. (See Other Achievements below.)
    Note that you do not need to beat a mission to collect a skull or black box.  
    Once you pick a collectable up for the first time, it is yours forever and you
    can quit the mission if you want.
    A. Mission 1: Alpha Base
    EVERYTHING’S BETTER WITH BACON (5):  This is one of the hardest achievements 
    in the game.  You have to ram 50 grunts.  You need to ram as many grunts as 
    you can before your gunners or marines shoot them, otherwise you will run out 
    of grunts to ram.  I recommend playing this one on normal or heroic to give 
    the grunts a fighting chance against the other UNSC units in the game.  I also
    recommend earning the Catch skull first (see Mission 10), and coming back and 
    trying this achievement later.  Turning on the Catch skull will recharge your 
    ram ability twice as fast.  
    Use only Sergeant Forge for ramming.  If you send in all your warthogs, it is 
    too hard to micromanage them and their guners will end up killing a lot of 
    grunts after they use their ram.  A normal warthog also doesn't have enough 
    health to go in ramming unsupported for the whole mission.  Every time you 
    have major group of grunts coming up, save the game.  Then send in Sergeant 
    Forge to ram the largest group.  Pull him out before his gunner can kill too 
    many grunts.  When his ram is recharged, send him in again until they are all 
    dead.  If you managed to ram over half the grunts, save and move on to the 
    next encounter.  If you didn’t, reload.  
    When you approach the vehicle barrier, you will have to act fast to prevent 
    the second group of marines from killing a large group of grunts before you 
    can ram them.  When you get the first group of marines under your control, 
    leave them behind and rush Forge over to the second group of Marines to ram 
    the grunts.  
    Send in only two marines to grenade the barrier’s power source.  Any more than
    two marines and you risk clogging up the doorway.  Send in Forge to ram any 
    grunts near the Wraiths, then send him out through the entrance to recharge 
    his ram.  This will trigger the bomber.  You want to avoid sending multiple 
    units into the base or the covenant infantry on the other side of the base 
    will charge and get caught in the bomber run.  If the bomber kills more than a
    handful of grunts, you should reload your last save and try again.  Keep 
    sending Forge in and out of the doorway, ramming grunts.  The Covies won’t 
    pursue you outside.  You should be able to ram enough grunts to get to 50.
    Skull: This is one of the hardest skulls in the game to unlock, for the same 
    reasons as the achievement.  Playing with the method used to earn the above
    achievement is also a good way to kill the 100 grunts needed to make the skull
    appear.  This can be tough because there are only a little more than 110 
    grunts total and you don’t get credit for grunts killed by the bomber or UNSC
    forces not yet under your control.  If you are still having trouble killing 
    100 grunts, play on heroic and turn on the Rebel Sympathizer skull (see 
    Mission 7). This will make the grunts tough enough that they should survive 
    long enough for you to put them down personally.  
    When you do kill 100 grunts, the Look Daddy! Skull will appear outside the 
    base entrance behind where you encountered the second group of marines.  You 
    may have to rotate the camera to see it.   Make sure you don’t kill every 
    covenant soldier in the base before you send someone to retrieve this skull.
    Black Box:  The Black Box for this mission is just before you encounter the 
    second group of marines.  When you cross the bridge leading to them, look to 
    the left (south) and almost under the bridge.  You will see the black box and 
    a green ramp leading down to it.  
    B. Mission 2: Relic Approach
    ENDLESS FUN (5):  You have to destroy every methane tank.  Methane tanks are 
    the tiny blue cylinders.  They are usually clumped together and you may 
    mistake them for resources at first.  The targeting reticule turns red when it
    is over them and they explode when you shoot them.  Just search every inch of 
    the map and keep destroying tanks until you get the achievement.
    Skull:  After you kill 20 Jackals, go back to the southwest area of your 
    starting base to find the Grunt Birthday Party Skull.
    Black Box: Go to the left (west) side of the map where you find the covenant 
    methane refinery.  Keep going up the left side until you see a vehicle barrier
    facing south.  The black box is behind that barrier.  
    C. Mission 3: Relic Interior
    COVENENT HOT DROP (5):  When Anders has raised the second bridge, move all 
    your units south across it.  Don’t forget and leave Anders behind (I did my 
    first time!)  Head south, but leave one unit near the southern bridge control 
    panel.  Covenant infantry will follow you from the north.  When there are five
    individual soldiers (not groups) on the bridge, click on the control panel, 
    bring up the circle menu, and deactivate the bridge.  The covenant on the 
    bridge will die.  If you didn’t get all five at the same time, you can 
    reactivate the bridge and lure more across, then deactivate it again.
    Skull:  After you kill 45 hunters, go back to where you rescued Forge and 
    Anders and you will find the Cowbell Skull.  If you can’t find enough hunters,
    stick around at the point where you are almost out of the relic and the AI 
    marines move in to cover you.  Hunters will spawn continuously from doorways 
    on either side.  They are suckers for the grizzlies’ canister shot.  
    Black Box: Before you enter the relic in the beginning, take the ramp to the 
    left.  Follow the little valley past the purple landing pad all the way 
    northwest alongside the outer wall of the relic.  The black box is at the end 
    of the valley.
    D. Mission 4:  Arcadia City
    THE REAL WINNER (5):  You have to save Adam.  I missed this one on the first 
    playthrough.  Adam, a lone fugitive child, is in the building directly north 
    of your starting location.  It’s the same building where you get the black 
    box.  If you listen carefully when you pass this building, you may hear a 
    woman's voice imploring you to save her son.  Click on the control panel to 
    open the door and Adam will emerge.  He will then run for a dropship.  Escort 
    him through the city.  He is very weak, so I recommend saving as soon as he 
    begins to run.  I also recommend waiting to unlock the door until the western 
    half of the city is relatively quiet and free of Covenant.  When Adam reaches 
    a drop ship, the achievement will unlock. 
    Skull: Once you have killed 50 elites, you can find the Wuv Woo skull almost 
    directly east of your eastern base near a statue.  Send a hornet after it.  
    In fact, send air units to get all the skulls and black boxes whenever you 
    can on every mission.  It’s much faster.  
    Black Box:  The black box is on the porch of the same building that Adam is 
    hiding in.  You may have to rotate the camera so that you are looking at the 
    building from the east to see it.  
    E. Mission 5: Arcadia Outskirts
    HE’S GOT THE JACK (5):  Undoubtedly an AC/DC reference.  You have three 
    Spartans and you need to jack six vehicles.  Once you secure the crater and 
    build a base, put your Spartans out in front of your defenses.  You don’t want
    your troops to blow up vehicles before your Spartans can jack them.  Jack weak
    vehicles like ghosts, then send them into combat until they are destroyed.  
    Your Spartan will hop out unharmed.  Use him (or her) to jack more vehicles.  
    You will also get a ton of Spartans later in the mission, so you can use them 
    to jack more vehicles.  Be careful not to jack too many wraiths.  It doesn’t 
    count as a kill and you need to kill five to unlock the skull.
    Skull:  After you kill five wraiths, the Fog skull will appear on the western 
    part of your map.  Get on the onramp to the east of your base and take the 
    freeway up the western edge of the map.  Or you can just fly there if you have
    Black Box:  As you are fleeing from the Covenant at the beginning of the 
    mission, go down the first staircase to your right (east).  The black box is 
    there behind a crashed pelican.  
    F. Mission 6: Dome of Light
    RHINO HUGGER (5):  You have to place the five rhinos without losing a single 
    one.  This means you have to protect them after they are in place too.  Don’t
    start ordering rhinos until you have built up your army.  Rhinos #1 and #2 are
    the must vulnerable.  They sit on Covenant attack paths and since they are the
    first ones you place, they will sit out there for a while.  Leave a couple of 
    wolverines and a cobra with each one in addition to the ODSTs the AI sends
    in.  Put infantry in the towers too.  Don’t worry about protecting #3, it 
    never seems to get attacked because it’s way off by itself.  Leave a wolverine
    with #4 just in case, but you plant #5 right after #4 so it should be okay.  
    Don’t forget to use your healing leader power on the rhinos if they get 
    damaged.  Save frequently.
    Skull:  You need to kill 50 banshees.  This is pretty easy.  Just make two 
    missile launcher turrets at the back of your base and you will eventually get 
    enough of them.  The Sickness skull is in the hanger to the south of your 
    base.  Rotate the camera until you are facing south to see it.  
    Black Box:  The black box is on the platform where you have to place Rhino #3.
    It’s to the east.  After you kill the Covies guarding the platform but before 
    you bring your units back, send someone slightly south and east to look for 
    the skull at the other end of the platform.
    G. Mission 7:  Scarab
    MICRO MANAGER (5):  You have to destroy the scarab without destroying any 
    power nodes.  This achievement is pretty easy on Easy Difficulty (you are 
    still playing all these missions on Easy, right?)  Start off by MAC blasting 
    the scarab.  For some reason when you MAC blast right away, the MAC gun is 
    immediately available again, so use it twice. Keep MAC blasting the scarab 
    whenever the power recharges.  In the meantime, stay in your base behind the 
    wall and keep pumping out fully upgraded warthogs.  
    After about nine MAC blasts, Serina will tell you the scarab is half dead.  At
    this point, the scarab should go crazy and try to burn through your wall.  It 
    will take quite a while, and you should have time for a few more MAC blasts.  
    When the scarab begins to burn through the second layer, save the game and 
    send your warthogs directly to attack the scarab.  Your units will auto target
    the power nodes, so move past them quickly.  If one of your over zealous
    gunners destroys a power node, you can’t get the achievement, so reload the 
    save you just made and try again.  You will lose a lot of warthogs but you 
    should finish the scarab pretty easily.  If you already have the Bountiful 
    Harvest and Emperor skulls from missions 14 and 15, you can earn this 
    achievement in less than 12 minutes.
    Skull:  I recommend finding this skull and the black box on a separate 
    playthrough from the achievement.  You will have to leave the base to hunt 
    down the 10 locusts required and whenever you leave the base, you risk 
    destroying a power node because your units will auto target them.  When you 
    kill the locusts, the Rebel Sympathizer skull will appear near the node in the
    upper left hand corner (northwest) of the map.
    Black Box: The black box on this map is in a niche just northeast of the power
    node directly east (right) of the scarab at the top of the map.  
    Sniper Tower Glitch: A glitch that you can use to help you destroy nodes and 
    get the black box and skull is to place a squad of marines in the sniper tower
    just to the north of your base.  The scarab beam will get stuck on them but 
    won't do any damage since the tower lifts them too high.  Make sure you have 
    given the marines the New Blood upgrade, otherwise the scarab beam will just 
    sweep past them as though they weren't there.  Go explore the map while the 
    scarab is busy, but keep an eye out because it will sometimes stop firing on 
    the marines and go back to sweeping the map.  Credit goes to V1per W0lf for 
    showing me this trick.
    WALK OFF WINNER (30):  If you finish off the scarab with a MAC blast, you can 
    earn this achievement.
    H. Mission 8: Ander’s Signal
    RAMBLIN’ MAN (5): Use the elephants to train 100 infantry (either marines or 
    flamethrowers.)  This achievement can be very time consuming.  Your maximum 
    population cap is 30, 40 after you research the reinforcements upgrade.  You 
    do the math: if you want to build 100 infantry, you are going to have to get 
    at least 60 of them killed to make space.  You might want to play this one on 
    normal or even heroic so that your troops will get killed faster and you can 
    replace them.  
    Build only infantry out of elephants.  Any vehicles you build will take up 
    population space you need to reach this achievement.  Don’t research the Medic
    upgrade and don’t heal your infantry units.  Instead, send weak units off by 
    themselves to die so you can train new ones.  You can carpet bomb your own 
    troops as well.  
    If you have recovered all the elephants and still haven’t gotten the 
    achievement, don’t bring the last elephant back to base.  Instead keep sending
    out infantry by themselves to die so you can train new ones.  Use skulls that 
    make the enemy stronger to make this process go faster.  
    Skull:  When you kill 750 infection forms (don’t worry, you’ll kill them 
    faster than you can train 100 infantry), the Rebel Supporter skull will 
    appear.  Look for it in the northwestern part of the map.  It's almost 
    directly north of the spot where the first AI elephant gets attacked.  There 
    is a pit with green mist and a large phallic column on the western edge.  The 
    skull is on a narrow ledge on the other side of the pit.
    Black Box:  The black box in this mission is on the hill behind the eastern 
    most (farthest right) units that were in the brute skirmish line at the 
    beginning of the mission.   
    I. Mission 9: The Flood
    SWEET NAPTIME (5):  You have to put every flood colony to sleep at the same 
    time.  There are five of them which get marked on your map when you put the 
    first one down.  The easiest way to do this is to leave behind a couple of 
    deployed cobras protected by a scorpion once you clear out all of the flood 
    around each colony.  When that colony awakens again, your heavy vehicles will 
    put it right back into hibernation.  It may take a little jumping around the 
    map on your part to make sure that they all get hit at once.  If you haven’t 
    gotten the achievement, don’t kill the flood boss and recover the Spartans 
    before you do or the mission will end.  
    Skull:  When you kill 20 flood stalks, the Rebel Leader skull will appear by 
    the nearest crashed pelican northeast of your base.  The pelican is on fire so
    it’s easy to spot even if that part of your map is blacked out.  I have had 
    trouble getting ground units up there, so send a hornet to pick it up.
    Black Box:  The black box is northwest of your base along the western edge of 
    the map.  Go past the first flood colony to the western edge and then head 
    south.  You will find a large valley.  The black box is near the beginning of 
    that valley.  
    J. Mission 10:  Shield World
    THE PROCRASTINATOR (5): You have to place a gremlin next to each of the four 
    tractor beams.  The tractor beams are laid out roughly in a square with one in
    each corner of the map.  The first is very close to your base to the 
    northeast.  The second tractor beam is north of the first one along the edge 
    of the map.  The third is just north of Alpha Team, the team with the grizzly.
    The fourth is just to the west of Charlie Team, the team with the Spartans.  
    When you clear out the enemies around the tractor beams, place the gremlin 
    on the blue circle.  Take gremlins with you when you rescue Alpha and Charlie 
    teams to save time.  Note that unlike the rhinos from Mission 7, the gremlins 
    don’t need protection once they are placed because the enemy will ignore them.
    Also note that each tractor beam you disrupt adds more time to the mission 
    countdown timer.
    Skull:  Once you kill 350 swarms, the Catch Skull will appear directly 
    northeast of your base past the first tractor beam on a large platform 
    inaccessible to ground units.  Send a hornet to pick it up.  
    Black Box:  The black box is sitting just behind (north of) Bravo Team, the 
    team with the elephant.
    K. Mission 11: Cleansing
    BATTEN DOWN THE HATCHES (5): You have to keep all the airlocks (vehicle and 
    infantry) from being destroyed.  Make sure you are playing on Easy Difficulty.
    Build lots of turrets in the sockets, with a mixture of flame mortar and 
    missile upgrades.  The cyclopes are useless.  They won't repair the airlocks 
    without being upgraded.  Build only hornets instead.  The most vulnerable 
    airlocks are the two infantry airlocks to the northeast and the lone vehicle 
    airlock by itself in the middle.  Keep an eye on these airlocks.  Make sure 
    they have turrets around them at all times and save your healing leader power
    to use on them if they take damage.  If an airlock gets in trouble, send your 
    hornets over quickly or use a carpet bombing run (just don’t hit the airlock.)  
    Skull:  When you kill 100 sentinels, the Sugar Cookies Skull will appear at 
    the front of the ship suspended in air between the two prongs.  You have to 
    use a flying unit to retrieve it.  
    Black Box:  The black box is on the left rear wing of the ship, right above 
    where the wing slants back upward and the ship becomes narrower.  It’s hard to
    spot, so try rotating the camera.  You have to send a flying unit to retrieve 
    L. Mission 12: Repairs
    HANDY WITH TOOLS (5):  You will have to do this mission twice to get the 
    achievement and the skull, since the achievement calls for beating the mission
    in four minutes and you won’t be able to kill enough dropships in that time to
    unlock the skull.  Get the achievement first, then play longer, kill more 
    enemies and get the skull the second time around.  You should also get a 
    higher score the second time, which will give you the CRUSHED COLORS (10) 
    achievement if you haven’t gotten it yet.
    To repair the power core in less than four minutes, you’re going to have to 
    work fast.  Begin by using your healing leader power on the core.  Then send 
    all your units over by the core and have the cyclopes start repairing it.  
    Build four turrets in the square in between the airlocks on the deck above the
    power core.  Later on, upgrade them with two flame mortars and two missile 
    launchers.  Queue up cyclopes in your infantry barracks until you run out of 
    money.  Don't build anything else.  Set the rally point for each airlock down 
    by the power core.  This way, when a cyclops comes out, he’ll already be 
    running towards the power core.  Don’t forget to task the cyclops to repair 
    the power core when he gets there.  The turrets should slow down the Covenant 
    that keep landing.  Build only cyclopes whenever you have enough resources.  
    Make sure that you have enough resources that you are able to use your healing
    leader power on the core whenever it recharges.  You should get this 
    achievement with a few seconds to spare.  
    Skull:  You need to kill 12 spirit dropships to get this skull to unlock.  
    This time, you want to build turrets all over the Spirit of Fire and upgrade 
    them to missile launchers.  The turrets will automatically kill all the 
    spirits for you.  The Boomstick Skull will appear on the ramp leading up to 
    the large superstructure at the front of the ship, just behind where the Sugar
    Cookies Skull appeared last mission.  Send a flying unit to pick it up.  Just 
    make sure you don’t finish repairing the core before you pick up the skull or 
    else the mission will end.
    Black Box:  The black box is directly to the left (northwest) of the power 
    core on the side of the ship.  Send a flying unit to get it.  Like last 
    mission, it’s hard to see, so try rotating the camera.
    M. Mission 13: Beachhead
    BEAMING WITH PRIDE (5):  You have to kill 25 units with a scarab.  The scarab 
    is southeast of the base in the middle of the map, across the light bridge.  
    Send ground units in; flying units won’t trigger the cut scene that makes the 
    scarab appear.  After you kill the flood stalks, jack the scarab with a 
    Spartan.  To make sure you get this achievement, save the game first, then 
    send in the Spartan controlled scarab by itself to a Covenant base.  Use your
    leader powers to help the scarab and use it to kill enemy units, not 
    buildings, until you get the achievement.  Don’t forget to turn on the Wuv 
    Woo Skull for added entertainment value.
    Skull:  After you kill 10 flood bomber forms, the Pain Train Skull appears.  
    It’s directly east of the first teleporter you used, by the flood mass growing
    out of the structure.  Send in a couple of hornets to grab it and get out 
    without bothering to fight the flood there.  If you are having trouble finding
    10 bomber forms, send a lage group of air units over near where the first 
    pelican was shot down at the beginning of the mission and scout the area.  
    That's usually where they hang out.  Just don't build at the last base site 
    before you get the skull.
    Black Box:  The black box is in the northeastern part of the map, on a hill to
    the north of the easternmost Covenant base.  
    N. Mission 14: Reactor
    DIDNT GET TO SECOND BASE (5):  Don’t build a second base.  If you are playing 
    on easy, your first base can give you everything you need if you take the time
    to build up.  When you destroy the Covenant bases, just keep going and finish 
    the mission to get the achievement.  
    Skull:  After you kill 20 Vampires, the Bountiful Harvest Skull appears.  It 
    is right next to the second Covenant base just to the northeast surrounded by
    large purple cylinders.  
    Black Box:  It is just to the left (west) at the top of the first ramp, to the
    southeast of the smoking hole in the ground and the resources.  It’s in a 
    clearing behind some trees, so you’ll need a flying unit to get it.    
    O. Mission 15: Escape
    THINKIN’ ABOUT MY DOORBELL (5):  You have to unlock the six panels in the 
    correct order.  This is done by unlocking two panels directly opposite one 
    another.  You can match up the same symbol or just do it as described here.
    If you call the panel directly in front of your base #1 and number the panels 
    from 1-6 in a clockwise order, unlock the panels as follows:  1-4, 2-5, 3-6.  
    You will finish the mission and get the achievement.  You can do it in any 
    order, as long as you always unlock the panel directly opposite.  Screw up the
    unlocking order and the panels will reset and you won’t be able to get the 
    achievement in that playthrough.  When you mess up, Serina will tell you that 
    an interlock has reset.
    Skull: You have to kill three scarabs for the Emperor Skull to unlock.  
    Scarabs come out infrequently and Serina will announce them by appearing and 
    talking about a large alien vehicle.  The scarabs seem to wander out onto the 
    panels in the middle of the map.  Freeze the scarab with a cryo bomb and then 
    hit it with your other leader powers.  If it’s still alive, send some flying 
    units to finish it off.  You also get credit for killing a scarab if you open 
    the door it's standing on and it falls into the hole.  After you kill your 
    third scarab, the Emperor Skull will appear in the middle of the northernmost 
    flood base.  It’s the one to the northeast of the black box.  Send in a group 
    of hornets to get it and one of them should pick up the skull before they are 
    shot down.  
    Black Box:  The final black box is north of your starting base on the other 
    side of the giant hole in the map.  It’s near the rim.  
    II. Other Campaign Related Achievements: 
    A. The Secret Achievements
    MEET SERGEANT FORGE (Secret) (10):  Complete Mission 1 on any difficulty.  If 
    you go mission by mission as described above, you’ll get this and all the 
    other secret achievements.  
    ICE WARRIORS (Secret) (40):  Beat Act I.  Finish the first three missions on 
    KEY TO PIRTH (Secret) (50): Complete Act II.  Finish missions 4-7 on 
    UGLY IS ONLY SKIN DEEP (Secret) (70): Complete Act II.  Finish missions 8-11 
    against the Flood.
    NO WAY HOME? (Secret) (70): Complete Act IV.  Finish missions 12-15 and thwart
    the Covenant plan.
    B. MOMMA’S BOY (5): Get a gold medal on any mission.  I guarantee that by the 
    time you beat the campaign on easy as suggested above, you will have gotten at
    least five gold medals without even trying.  
    C. CRUSHED COLORS (10):  Improve your score by replaying a campaign mission.  
    Very easy.  Don’t go out of your way for this one.  If you haven’t got it by 
    the time you get to mission 12, you will have a chance to earn it as noted 
    D. OWN WORST ENEMY (20):  Get a gold medal with all debuff skulls activated.  
    The debuff skulls are Fog, Sickness, Rebel Sympathizer, Rebel Supporter and 
    Rebel Leader.  Play mission 1 on Easy Difficulty and activate these skulls as 
    soon as the mission starts.  It’s not very hard.  
    E. WALL OF RECOGNITION (30):  Get a gold medal on every mission.  You can do 
    this on the Easy Difficulty, but gold medals add up across all difficulties 
    and co-op too.  When you have finished going mission by mission as noted 
    above, look at your service record and see what missions you didn’t earn a 
    gold medal on.  Replay those missions, but don’t use the skulls that lower 
    your score.  If you are having trouble with a particular mission, remember to 
    do all the optional objectives along the way.  These earn you massive bonus 
    points.  Taking very few casualties will increase your score multiplier at the
    end of the mission, as will finishing in under par time.
    Some people have been asking me for tips for specific missions, so here they
    Mission 7:  Mission 7 intimidates a lot of people.  I know it scared me the 
    first time the scarab beam wiped out half a dozen of my units.  Nevertheless,
    it is possible to beat this mission in par time getting all objectives without
    losing a single unit.  That will get you a 10x combat modifier which will 
    assure you of gold.  The fewer casualties you take, the higher that multiplier
    will be.  Play on easy with no skulls.  Build only fully upgraded gauss 
    warthogs and keep MAC blasting the scarab.  When you have about a dozen 
    warthogs, send them out to destroy power nodes.  Save the game each time you 
    are about to venture out of the base.  Then look at where the beam is pointing
    and head in the opposite direction once it sweeps by.  Take cover when the 
    beam begins to sweep back your direction.  The east side of the map and the 
    southwest side have the most cover.  After every couple of nodes, return to 
    your base to heal and pick up the warthogs you've been cranking out this whole
    time.  Destroy all seven nodes and ten locusts (there are eight on the map to 
    start with but dropships will bring more periodically.)  When you have done 
    the optional objectives, time the beam and when it is pointed all the way to 
    the right or left, send your warthogs up near the scarab on the other side.  
    If you have been MAC blasting the scarab and building warthogs the whole time
    (you should now have about 25), you will be able to finish it off before the 
    beam swings back to you.  Leave your slower units, like tanks and marines, 
    back at base so they don't get killed and cost you points.  If you are having 
    trouble timing the beam, try the sniper tower glitch described above.
    Mission 10: To get a gold on this mission, build up a mixed army of wolverines
    and scorpions.  Vehicles seem to resist damage from the flood units better 
    than aircraft or infantry.  When you hit the population cap of 30, cryo bomb 
    the first group of swarms and send your vehicles in.  After you rescue alpha 
    team, heal your vehicles and go after bravo team.  Rinse and repeat for charlie
    team.  Send gremlins to disrupt all the pylons while you are near them.  The 
    only hard part about this mission is the large number of thrasher forms (they
    look like lumbering bears.)  After you rescue bravo team, they will start 
    spawning in groups of five or more in the middle of the map.  Don't let any 
    units wander around by themselves or in small groups and you should be fine.  
    Keep up your base defenses because the flood will launch a massive attack on 
    your base after you rescue charlie team.  I got a gold on this mission without
    even killing enough swarms to get that optional objective.  Play it on easy of
    F. EPIC GRINDER (40):  Get a lifetime campaign score of over one million 
    points.  By the time you’ve had to play and replay all the missions on easy 
    chasing other achievements, you should get this.  If you still don’t have it, 
    start the hard and legendary playthroughs and you’ll get it before too long.
    G. ADJUDICATE THE ARBITER (30)/ MR. PUNCTUAL (15):  You have to beat the 
    campaign on heroic anyway for the first achievement, so you might as well do 
    it under par time and get the second achievement.  If you’ve already played on
    easy and picked up all the achievements, skulls, and black boxes as suggested 
    above, you can just focus on finishing the main objective as fast as possible 
    and ignoring everything else.  If you are really a masochist, you can get MR. 
    PUNCTUAL while playing on Legendary instead.  Playing on Legendary will also 
    earn you ADJUDICATE THE ARBITER because the achievements stack.  Here are some
    tips for playing the harder missions on Heroic.
    General Tips:
    1. Don't worry about optional objectives, skulls, black boxes, casualties, or 
    your final score.  Just beat each mission as fast as possible by rushing the 
    main objectives.
    2.  To that end, on most missions you don't need to build the Reinforcements 
    upgrade and fill your army out to 40 or get to Tech Level 4.
    3. Always turn on the skulls that help you.  (Catch, Sugar Cookies, Pain 
    Train, Bountiful Harvest and Emperor.)  Use the Bountiful Harvest and Emperor 
    Skull to abuse your leader powers.  The healing power will recharge in less 
    than 2 minutes with the Emperor Skull on.
    4. Do NOT play with the Cowbell Skull on!  Your game does not need more 
    cowbell.  The Cowbell Skull can cause some crazy things to happen on Heroic.  
    Crazy things like the civilian cargo plane in mission 4 randomly exploding 
    when it is at full health with a healing ring on it and no Covies in sight.  
    5.  Do NOT play with the Boomstick Skull on!  The explosions can damage your 
    units as well.  If one or two flood explode in the middle of your army, they 
    can cause a chain reaction that can wipe out your whole army at once.  Don't 
    ask me how I found that out.  Also be aware that Sergeant Forge or a warthog 
    will take a ton of damage if they ram an enemy who explodes.   
    Times:  There is a list of the par times posted on gamefaqs.com under the 
    Cheats heading.  Rather than steal someone else's work I will refer you there.
    On almost all these missions, time isn’t really an issue when you are only 
    going for the main objectives.  Note that you only have to finish faster than 
    the higher time to get credit for beating par.
    Tips for the Harder Missions:
    Mission 4: This is by far the hardest mission.  Start off by rushing Forge and
    the Hornets over to the Subway entrance.  You have to clear it in less than 
    three minutes if you want to make par time.  After you finish that, send your 
    units up towards Cargo #2, clearing the Elites out of the sniper towers as you
    go.  Use Forge to defend Cargo #2 and send the hornets to destroy any wraiths 
    or locusts you can find.  When Cargo #3 explodes (you can't prevent it), send 
    the hornets to defend Cargo #2 and send Forge down to the first base build 
    Forget about earning points or saving civilians.  It's hard enough just to 
    have one ship survive for 20 minutes.  You should abandon Cargo #1 and 
    consolidate your defenses around Cargo #2.  When Cargo #1 is destroyed, the 
    Spartans will retreat to Cargo #2.  Hopefully at least two Spartans will make 
    it over.  Otherwise you have a much harder job.  Crank out marines and 
    warthogs to defend Cargo #2.  Resources are very tight in this mission, but if
    you are able to make wolverines, they come in very handy.  Use your healing 
    power on Cargo #2, as soon as it takes any damage.  Once you have two turrets 
    built at your base, send Forge back to Cargo #2.  Stick marines in the sniper 
    towers on the paths to Cargo #2 and put vehicles and marines at the eastern 
    edge of the landing platform to intercept Covenant aircraft.  The banshees are
    especially dangerous because they can suicide crash into Cargo #2 and cause a 
    lot of damage.  Upgrade your marines to ODSTs late in the game so you can drop
    them directly near Cargo #2.  Most importantly, save frequently, every two 
    minutes, and only save when Cargo #2 is at full health.  Save when there is 
    1:20 left, because with a minute to go, the covenant mega turrets will come 
    online and begin bombarding the platform.  Usually, they don't hit Cargo #2 
    enough times to destroy it, but in case they do, you want to be able to 
    reload.  After 20 minutes of insanity you will beat this mission. 
    Mission 6:  This is the only mission where coming in under par time poses a 
    challenge.  You have to beat this one in less than 30 minutes.  Before you 
    plant the first rhino, send some heavy vehicles over to where the second rhino
    will be planted (the next platform to the west.)  After you plant the first 
    rhino, covenant buildings will spawn at the second rhino site.  Your heavy 
    vehicles will ambush them and demolish them quickly before they can begin 
    pumping out units.  You can wipe out all the covenant before Forge complains 
    about there being a covenant base there.  After you plant the third rhino, the
    AI begins to drop lots of infantry on your base, including fully upgraded 
    hunters, which take forever to kill.  Make sure you have a full army and at 
    least ten minutes after the planting the third rhino and save the game.  
    Send your troops to the fourth rhino plant site.  Before you finish clearing 
    it out, the Covenant will be assaulting your base in full force.  Pelican 
    transport the fourth rhino over.  Keep pumping out units to slow them down, 
    but don't bring your main army back to the base.  Instead, send them to the 
    fifth rhino platform.  When you order your fifth rhino, immediately pelican 
    transport it over to its blue circle to save time and prevent the forces 
    attacking your base from damaging it.  If you send your main army back to 
    defend your base, you will lose too much time and might not make it in 30 
    minutes.  Don't worry about your base.  You should plant the last rhino before
    the Covenant do too much damage to your base.
    Mission 7:  This mission is a lot easier than I thought it would be.  The 
    basic strategy is the same as earning the gold medal on easy, except you will 
    want a few more heavy units in your base for defense and you shouldn't bother 
    wasting MAC blasts on the scarab because they do so little damage.  Quickly 
    build up an army of gauss warthogs and send them out marauding to destroy 
    power nodes.  Build some heavier vehicles too but keep them in your base for 
    defense.  When you have destroyed five or six nodes, time the beam's movement
    and send all your vehicles to attack.  When the beam swings back towards them,
    hide them behind some ruins or just run them the opposite way through the beam
    if you don't mind losing a few vehicles.  You should take down the scarab with
    plenty of time to spare.
    Mission 9:  Not really a hard mission, but there is a way to beat it very 
    quickly. Stay in your base and build up an army of upgraded hornets.  Also 
    upgrade your carpet bomb power.  When you have about a dozen hornets, fly 
    them directly north to the star marking Red Team's location on the map.  From
    there, fly northeast to the giant Flood brain thing.  Carpet bomb it and then 
    attack with your Hornets and Spartans.  You will lose a lot of hornets to the 
    flood turrets, but you will take down the Flood boss very quickly while 
    bypassing most of the level.
    Mission 15: On mission 15 I like to build up an army of hornets and ODSTs.  
    This army takes a lot of casualties but stays cheap and mobile, the keys for 
    beating this mission quickly.  Soften up the enemy around the control panel 
    you are heading to with your leader powers, then rush your hornets over, 
    pelican transport the Spartans, and drop ODSTs to clear the enemy out.  Avoid 
    engaging the scarabs: they take a lot of time to kill and can put a big dent 
    in your army. 
    H. DETOUR THE GREAT JOURNEY (50): Beat the campaign on legendary.  The 
    heroic strategies work most of the time, but expect the enemies to be much 
    tougher and more numerous and aggressive.  Since par time isn't a factor for 
    this achievement, move slowly and deliberately, but you can still ignore 
    optional achievements and collectables like you did for heroic.  Don't forget 
    to turn on the skulls and save frequently.
    One general tip:  research ODSTs on any mission you can.  You'll know are 
    available if at the begining of the mission the ODST icon appears on the 
    powers circle menu.  Don't train ODSTs out of your barracks.  Instead, when 
    you take casualties assaulting objectives (and you will take lots of 
    casualties), use ODST drops to quickly reinforce your main army.  They are a 
    very powerful unit with a very low cost.  Here are a few more tips for 
    missions that are much harder on legendary than they are on heroic:
    Mission 5: You are very vulnerable early on in this mission.  Start off by 
    putting a Spartan in your scorpion tank, otherwise it will never survive the 
    trip into the crater.  When you get your base built, put your expensive 
    buildings (like reactors) on the east side so they don't get hit by the Mega 
    Turret.  This is a very hard mission.  If you can hold out until Spartan Team 
    Omega arrives, you'll be okay.  It becomes ridiculously easy when you have 
    nine or ten Spartans.
    Mission 12:  The strategy of building as many cyclopes as possible and beating
    this mission as fast as you can won't work on Legendary because you will be 
    overwhelmed.  You only need about five or six cyclopes.  You should spend most
    of your resources on flame turrets, but build a railrun or two to damage 
    locusts.  Don't forget to build turrets in the sockets at the bottom of the 
    ramps nearest the core.  Use your units to target hunters and locusts whenever
    you see them because they can inflict the most damage on the core.   Use the 
    healing ring on the core whenever you get a chance and position all your 
    units within it to heal them up too.  
    Mission 14:  The Covenant send many more troops at a time on Legendary and can
    easily destroy the reactor early in the game.  Build an elephant as soon as 
    you start the mission and drag the reactor back behind your base until you 
    build up your forces.  Move out only when you are at full strength.  Put a 
    Spartan in the elephant dragging the reactor when you start moving to increase
    its defense.  Watch out, the Covenant will send scarabs after you, so upgrade 
    your MAC cannon as soon as you can and use it only on scarabs, bases, or very 
    large troop concentrations.
    III. Skirmish Achievements
    Before you attempt the Skirmish Achievements, I highly recommend that you get 
    all the skulls from the campaign first, especially the skulls that help you 
    while lowering your score (Catch, Sugar Cookies, Boomstick, Pain Train, 
    Bountiful Harvest and Emperor.)  The skirmish achievements can be earned while
    those skulls are active and your job will be a lot easier and quicker.  You 
    should also play against an easy AI, unless the achievement calls for an 
    heroic AI.  The skirmish acheivements that don't call for an AI opponent can 
    also be earned on XBox Live multiplayer. 
    A. 2 BUGS ARE BETTER THAN 1 (10) and PENNY PINCHER (10):  You might as well 
    earn these two achievements at the same time, since with two scarabs you don’t
    need to build more than ten units.  Select a 1v1 map and the heroic AI and 
    play as the Prophet of Regret.  Use the Prophet for base defense and to take 
    over a second base while you accumulate resources and research technologies.  
    Fully upgrade your turrets and the Prophet, but don’t build or upgrade any 
    units other than a couple of engineers for healing.  The prophet and turrets 
    should be able to fend off any attack.  To build two Scarabs, you will need to
    research the Ages of Doubt and Reclamation at your Temple, as well as the 
    Followers upgrade.  Once you have two scarabs, use them to crush the enemy and
    get two achievements.  
    B. WALK OFF WINNER (30):  You have to kill the last enemy unit (not building) 
    with a leader power.  The easiest way to do it is be the Prophet of Regret and
    wipe out all of a human enemy’s units and bases except one.  Use the Prophet’s
    fully upgraded cleansing beam on the base and position it right at the end of 
    the ramp.  When the AI makes infantry to defend the base, the first infantry 
    unit will come out of the ramp right into your beam.  Since it is the only 
    unit left, you will get the achievement when you kill this unit, even if the 
    AI makes other units afterwards.  Just make sure your own units are far enough
    away that they don’t steal the Prophet’s kill.  This achievement can be easily
    earned during the same game as 2 BUGS ARE BETTER THAN 1 and PENNY PINCHER.  
    You can also earn this achievement during the campaign.  An easy way is to 
    finish off the scarab in Mission 7 with a MAC blast.
    C. BIG AL’S SCOOTER (10):  You must defeat the Heroic AI in under ten minutes.
    This achievement encourages you to practice a rushing strategy.  Select an 
    Heroic AI opponent and a Covenant leader for yourself (the Prophet works 
    well.)  Choose a small 1v1 map.  I find Chasm, the map from the demo, works 
    best.  Begin by building a leader temple and a bunch of warehouses.  Select 
    your base and move the rally point on top of your grav lift.  Any new units 
    will now teleport directly to your leader.  When your leader emerges, send him
    to the enemy base and begin building your special forces units out of the main
    base.  Save your leader power until you see an emerging building or turret.  
    They are much faster to kill while under construction than when fully 
    finished.  Keep building units to send to your leader as he attacks the enemy 
    base.  You should finish off the enemy and get the achievement with a few 
    minutes to spare.  If you are having trouble, remember to turn on skulls to 
    make it easier.  
    I've found another great strategy is the elephant rush suggested in the tips 
    that crawl accross the bottom of the menu screens.  Play as Cutter.  Just 
    build an elephant and a bunch of supply pads and send the elephant to the 
    enemy base.  If the Covenant leader attacks your elephant, use your warthog to
    distract him.  Keep pumping out infantry.  It took me about five minutes to 
    beat the heroic AI like this without any skulls.
    A third strategy is to play on deathmatch.  Use Anders, build hawks, and rush 
    the AI base.
    D. TITAN (15):  Scoring 20,000 points in a skirmish game is easier than you 
    think, but it will take some time.  Select a 1v1 Deathmatch game against an 
    easy AI on Release, the 1v1 flood infested map.  Choose Sgt. Forge and pick a 
    Covenant leader for the enemy.  Don’t turn on any skulls that lower your 
    In Deathmatch, you start off with all technologies unlocked and a ton of 
    resources.  Build grizzly tanks and Spartans and take over each flood base, 
    but don’t attack the covenant base.  Keep growing your army and building 
    vehicles and turrets until you reach the max population cap of 45.  
    In each upper corner, there is a forerunner control panel that releases flood.
    Garrison each one with a Spartan.  Look to the north of your first base.  You 
    will see a flood structure with an open mouth and a ramp that ends in a blue 
    circle.  Look across the flood barricade in the middle to find another blue 
    circle on the Covenant side.  When you release the flood, this is where they 
    will come out.  Surround each blue circle with grizzlies and a couple of 
    wolverines in case flying flood are released.  Release the flood gates and 
    watch your tanks kill the flood that emerge.  Do this over and over again, 
    healing your troops periodically.  The gates reset every couple of minutes 
    (although not if you keep holding the blue circle menu open on them.)
    When you have enough points, turn on all the skulls that increase your score 
    and wipe out the Covenant base.  Check your in-game score with the back 
    button.  Remember that your final mission score is multiplied by a combat 
    multiplier.  I only lost a couple of units and buildings, so I had a 
    multiplier of 6x.  I ended my game with over 7000 points and ended up with a 
    score of over 48,000!  You should be able to finish the game when your in-game
    score reaches 4000 and be reasonably assured of getting this achievement in 
    about half an hour.  
    E. EMPIRE BUILDER (5): You get EMPIRE BUILDER for winning both a Skirmish and 
    a Deathmatch game.  If you play these achievements in the order listed here, 
    you’ll get this when you get TITAN.  You can also get this playing 
    F. MY VIRTUAL FRIENDS LOVE ME (10):  Select a 3v3 map with six players.  Put 
    the AI on easy and when the game starts, turn on your favorite skulls.  
    Remember to play with a leader and map you haven’t used yet to save time for 
    the next achievements.    
    gotten the skirmish achievements listed above, it’s time to go for the 
    grinding skirmish achievements.  These achievements can be time consuming, so 
    here’s an easy strategy.  Check to see what maps and leaders you haven’t used 
    to win a game yet (under Options and Extras then Service Record from the main 
    menu.)   Play 1v1 Deathmatch (not Skirmish) on the rest of the maps against an
    easy AI opponent.  (Just like the third BIG AL'S SCOOTER strategy except you 
    don't need to play against an heroic AI.  Turn on all the skulls that help 
    you.   Build up your best units and rush the AI base.  Anders is my favorite 
    leader, because her Hawks can fly over terrain and save you a ton of time.  
    Build an airpad and seven Hawks and a barracks and three Spartans.  Send the 
    Hawks over to the enemy base and follow up by Pelican Transporting the 
    Spartans and your Warthog over too.  Depending on the size of the map, you 
    should defeat the enemy in just over 4 minutes.  Do this on each map to save 
    yourself a lot of time in getting GALLIVANT AROUND THE GALAXY.  Just remember 
    to try each of the six leaders once while you get that achievement to earn 
    PLAYIN’ THE FIELD.  You can also get these playing multiplayer. 
    IV. Multiplayer Achievements
    A.  BASICALLY NAIVE (10): You can earn this achievement quickly and easily.  
    Just go into a Multiplayer game on Xbox Live.  When the game has begun, 
    resign.  You will get a recruit rank and an achievement.  Just make sure to do
    it in a 1v1 game so you don’t anger your teammates who were counting on you.  
    B.  N00B N0 M0R3 (10) and LONELY AT THE TOP (20): If you actually stick around
    and win your first 1v1 multiplayer game, you will unlock N00B N0 M0R3 (for 
    winning your first match) and LONELY AT THE TOP (for getting the highest 
    score).  These two achievements aren't that hard to earn.  Keep playing 1v1 
    games and eventually you will run into someone worse than you or someone who 
    resigns and earn them both in the same game. 
    C. OFFICER ON DECK (30) and RUNNING THE SHOW (50):  Note that your online 
    rank is different from your TruSkill level.  Your rank is based on experience 
    points and you earn points even in a loss, so even a bad player (like me) can 
    eventually get the higher ranks and the OFFICER ON DECK and RUNNING THE SHOW 
    achievements.  Never quit out of games, even when you are losing badly or 
    really have to go.  Leaving early will cost you points.  Instead, just self 
    destruct all your bases and wait around for one minute until you lose.  You 
    get a 40% points bonus for winning a match, a 20% bonus for losing without 
    quiting or resigning, and no bonus if you disconnect or resign.  On team 
    games, you can quit after you are fully defeated without penalty and you don't
    have to stick around to watch your teammates get beaten up.
    You need 80,000 points for OFFICER ON DECK. I recomend playing deathmatch as 
    you seem to get more points per game.  I played 24 games of 1 v 1 deathmatch 
    with 19 wins.  (I guess I wasn't as bad as I thought.)  I earned 76,684 
    points, or about 3195 points per game.  Most games were around the 15 minute 
    mark, with a few being as short as 7 minutes and a few as long as half an 
    hour.  I earned the rest of my points playing a few multiplayer games with 
    friends.  I think most players could earn 80,000 points with about 20-35 games
    of deathmatch.  You need 3,200,000 points for RUNNING THE SHOW!  That's going 
    to take forever, but if you want to try, more power to you.   
    V. Other Achievements
    A. HALO ACADEMIC (15)/ HALO HISTORIAN (40):  You get these achievements by 
    unlocking timeline events.  Timeline events are unlocked by black boxes and 
    playing skirmish games with different leaders and maps.  If you get all the 
    black boxes described above in the Campaign section and follow the strategies 
    in the Skirmish section, you will get both of these achievements.  
    B. 24 HOURS OF QUALITY (20):  You have to spend 24 hours playing the game.  
    If you go for all the Campaign and Skirmish achievements, you will get this 
    before you get all of the achievements.  If you just want the achievement with
    minimal time on your part, try playing skirmish games on easy with the skulls 
    on.  Fully build up your army and base and leave them in good defensive 
    positions.  Try the Covenant because their shields regenerate automatically.  
    Leave your game running and get on with your life.  Your troops should last 
    quite a while without your help.
    C. READY FOR THE SEQUEL (75): READY FOR THE SEQUEL unlocked when I got TITAN, 
    so it is based on earning other achievments.  Here are the achievements I had 
    when I unlocked it (without listing lesser included achievements like HALO 
    the secret campaign associated achievements, and each of the 15 mission 
    specific achievements.  In simpler terms, you need all of the campaign and 
    skirmish related achievements you can earn on the Normal or Easy settings.  I 
    also had BACKSCRATCHER and BASICALLY NAIVE, but I don't think they are 
    necessary. I have also heard rumors that this achievement may be glitched and 
    sometimes won't unlock.
    D. BACKSCRATCHER (10)/ OMG BFF FTW (40):  Get a friend who also has Halo Wars 
    to join you.  If you can’t find a friend, post a message on a bulletin board 
    or forum like gamefaqs.com requesting a partner for the achievement, the 
    missions you want to play, and how long you plan to be online.  Of course, I 
    recommend playing on easy to make the missions go faster.  BACKSCRATCHER is 
    easy to get.  You earn it after finishing your first co-op mission.  OMG BFF 
    FTW can be time consuming as you have to finish all the missions.  You can see
    what missions you have done on co-op by checking your service record.  Don't 
    forget that you can use your favorite skulls in co-op too.
    VI.  Stategic Options DLC Achievements
    The achievements for the first DLC content can be earned in skirmish mode 
    against an AI with skulls on.  You can also earn them over XBOX Live 
    multiplayer if you want.  They are all very easy.
    A. ONE AND DONE (30): Set up a 1v1 Capture the Flag game with against a 
    Legendary AI.  When the game starts, begin building as you would in a normal 
    skirmish game and send your scout towards the middle of the map.  The flag, a 
    floating sentinel, will soon appear in a random spot near the middle of the 
    map.  Grab it with your starting scout unit and run back to your base.  If the
    enemy pursues you, go in circles around your base or another natural obstacle 
    until the capture timer expires and you get a point.  If the AI gets ahold of 
    the first flag before you do, quit and start over again to save yourself time.
    Focus on building aircraft.  The flag sentinel will move across the map and 
    can end up over terrain obstacles that are only accessible to flying units.  
    Flying units are also faster and can get to a flag quicker.  In addition, 
    a flying flag carrier can use inaccessible terrain to hide from ground units.
    Build up your base defenses so your flag carriers have somplace to fall back 
    on and never send a slow or wounded unit to pick up the flag.  I think the 
    Covenant have an advantage in this game mode because their leaders make 
    incredibly powerful flag carriers early in the game.  The Legendary AI 
    doesn't pose much of a problem and if you can capture three flags first, you 
    will win the game and get the achievement.    
    B. PULL HARD, PULL DEEP (20): This achievement is ridiculously easy.  Play a 
    1v1 Tug of War match against an Easy AI.  Turn on your favorite skulls.  
    Employ your favorite rushing strategy.  In my experience, the AI is a sucker 
    for the elephant rush.  Assuming that you get the first kill in this game, 
    when you beat the AI in about 4 minutes you'll get this achievement.  
    C. FREAK ON A STREAK(20)/ LIVING LOVING BUG(30): You can earn both achievments
    in the same match.  Set up a 1v1 Reinforcements game against an Easy AI.  
    Reinforcements lets you build up resources as the timer counts down, then when
    the timer reches zero, it spends your resources on troops.  The amount and 
    quality of troops you get is based on the amount of resources you have to 
    spend, your tech level, and how much space you have left for troops.  
    Play as the Prophet of Regret.  Use your incoming waves to take over extra 
    bases, but don't attack the enemy base.  Don't worry about casualties and 
    don't take the free resources on the map yet.  Build up nothing but warehouses
    and a temple and upgrade only your prophet and turrets.  You want to research 
    the highest tech level possible as quickly as you can while not filling up 
    your army with weak low tech units.  Spend as many resources as you can before
    the timer runs out so you don't get a bunch of useless troops.  If your army 
    starts filling up with grunts and other crappy troops, gather your units 
    together and use the Cleansing Beam on them to make more room.  Research the 
    Followers upgrade too.  When you have three bases with five fully upgraded 
    warehouses on each one, you should be easily pulling in 3500+ resources in the
    minute and a half it takes the timer to run down.  When this happens, gather 
    all the resources on the map and don't spend any money.  If you have the space
    in your army, you should get a reinforcement wave worth 15 population for the 
    FREAK ON A STREAK achievment.  If you have a tech level of 3 or higher, over 
    3000 resources, and at least 20 free population spaces when the timer expires,
    you stand a good chance to get a scarab on that wave to earn LIVING LOVING
