    SECTION 1	Introduction:
    	This document is a guide to combat in the Playstation games Syphon Filter and
    Syphon Filter 2 (when refrring to the first game, I will use the term Syphon
    Filter 1 or SF1, when refering to the second, I will use Syphon Filter 2 SF2; I
    will refer to the entire series as Syphon Filter or SF).  It details tactics
    and strategies for playing the games' action segments.  There are no secrets,
    cheats or walkthroughs, just tips on how the game works and how to play it
    well.  However, if you are new to Syphon Filter and need some tips on how to
    play, or if you are a veteran of the series but want to improve your skills,
    read this guide.
    	Some of the tips in the first strategy section (Section II) is not specific to
    Syphon Filter; they were actually taken from tactics hyenas use in predation
    and dealing with rival predators.  However, I wrote on how these apply to the
    game and how to use them.  Hyenas are so smart.  And fluffy.  The other
    strategy sections and Syphon Filter specific; they give details on game
    mechanics and specific strategies.

    [fluffyhyena@hyena.g2gm.com] laughing-hyena-velox@rock.com and please use
    ďSyphon FilterĒ as your subject heading so it doesnít get mixed up in my
    hyena-mail and junk-mail.
    Hyenas Forever!

    SECTION 3	General Tactics:
    	Dodge fast and bite hard!:
    	This is a very effective tactic, taken from situations where hyena packs face
    off against lions.  Attack or pursue an opponent, but back off or dodge when he
    faces you to avoid a counterattack.  In Syphon Filter pretty much every enemy
    has a ranged weapon; backing away probably won't help but moving behind cover
    does.  For quickly popping in and out, try using manual aim and using to L2, R2
    and X buttons to pop up and quickly return to a safe position.  Also, watch the
    danger meter; it tells you whether an enemy is targeting you and how close he
    is to actually hitting you.  When it flashes, it's time to dodge or kill your
    antagonist quickly.  When moving out of an enemy's way, don't forget to roll;
    it decreases your chances of getting hit.
    	Don't waste carcasses:
    	Hyenas waste nearly nothing; they will eat the carcasses of fallen opponents
    and rivals (after the fighting stops, of course).  In Syphon Filter it is
    EXTREMELY important to search every killed enemy for items, weapons and
    ammunition.  Half the weapons and ammo you get comes from your opponents.
    	Opportunity can sometimes be a hyena's most potent advantage.  A hyena can
    find ways to acomplish a goal without working as hard, in ways such as
    attacking prey that is weak or distracted, and taking on lions when they are
    outnumbered or wounded.  In Syphon Filter taking on a distracted enemy or
    waiting for the right moment to strike can mean the difference between survival
    and defeat.  It is possible to rush an opponent with the knife when it is
    reloading or hesitating, and taking down a distracted foe can get you an easy
    ammo pickup.
    	Retreat when approached:
    	When hyenas are attacked by lions, they will sometimes initially retreat, but
    regroup and counterattack.  In Syphon Filter, itís often a good idea to back
    off when a group enemies appears, then use the in-and-out strategy discussed
    above to eliminate them.  Taking on a group of opponents and letting them
    surround you is never a good idea.
    	Assume a Defensive Position:
    When a single hyena is attacked by a group of antagonists, it will assume a
    defensive crouch and fend off its attackers.  In Syphon Filter crouching behind
    cover is an effective defensive tactic.  Remember that you canít hold position
    indefinitely; youíll have to counterattack eventually.  However, a good
    defensive position helps you take on enemies at your own pace.
    	Attacking Legs:
    	Legs, despite containing any vital organs, are important to survival.  For
    example, a hyena or hyena pack bites the legs of prey to make it collapse or
    slow.  This works somewhat in Syphon Filter; although head shots are preferred,
    a shot to the leg often negates any protection an enemy might have from a flak
    jacket.  With the air taser a head shot and leg shot have the same effect
    (electrocution).  However, damaging the legs does not actually cause tripping
    or falling because of game engine limitations.  Note that shooting the legs
    might cause less damage than a body shot if the enemy in question doesn't
    actually have a flak jacket.
    	Groups of hyenas isolate their enemies or prey to make them easier to pick
    off.  It's a lot easier to grab a wildebeest calf when it's unprotected. 
    However, in Syphon Filter, you usually won't have an ally to help you, and if
    you do, they probably won't act as a distraction while you pick off enemies. 
    The trick is to position yourself so that only one enemy can fight you at one
    	Don't always fight:
    	Sometimes, it's best to run when confronted with bad odds.  A single hyena
    can't hope to take on an entire pride of lions.  When retreating in Syphon
    Filter, it's best to remember that enemies can still shoot you from far away,
    so try turning corners or crouching behind cover when pursued.  Sometimes you
    might have to settle for shooting only the enemies in blocking your path and
    avoiding the others.  When running from enemies, don't forget to roll.  Note
    that most of the time it's best to eliminate as many enemies as possible;
    retreat when you're desperate, not when you have a chance.
    	It is also a good idea to simply evade enemies while completing non-combat
    objectives; it is useless to try to fight every enemy when your priority should
    lie in the mission goals.  A hyena disptuing a kill with African wild dogs
    doesn't bother biting at every dog, it goes in and grabs the meat.
    SECTION 4	Weapons
    How weapon descriptions are structured:
    Name: (name of weapon)
    Clip size: (number of shots in one clip/how many clips you can carry)
    Ammo Capacity: (for weapons without clips, how much ammo can be held inside)
    Weapon size: (whether the weapon is large or small, which determines its firing
    Pickup: (how much ammo you get from taking an enemy's weapon)
    Damage: (how much damage it causes, taking into account firing rate.  This is
    based on what it seems like in-game, rather than manual or pause screen
    Firing mode: (semi-auto, automatic, etc.)
    			Semiautomatic - fires every time you press the fire button
    			Automatic - fires until you release the button
    			Manual Reload - fires once and then must be reloaded or reset
    Description: (how it can be used, how good it is in, availability, etc.)
    While some information is taken from the in-game descriptions, I have made
    adjustments based on experience.  The damage rating is not the damage from one
    shot, but how much damage the weapon can cause given any period of time.  For
    example, the G18, while average in damage, fires so fast that it causes enough
    damage to be rated as a more powerful weapon.
    9mm Semiautomatic
    Clip size: 15/6
    Weapon size: Small
    Pickup: 10
    Damage: Low-Medium
    Firing mode: Semi-automatic
    Description: The 9mm is an okay weapon that causes a bit of damage and being
    semiautomatic, has a decent firing rate.  However, you can usually get better
    weapons.  Ammo doesnít show up often for this weapon, but it really isn't
    reliable anyway.
    .45 Semiautomatic
    Clip size: 10/6
    Weapon size: Small
    Pickup: 10 (full clip)
    Damage: Heavy
    Firing mode: Semi-automatic
    Description:  The .45 is a powerful weapon and causes one-shot kills at close
    range.  However, it really doesn't have much ammo capacity.  However,
    ammunition is plentiful in some situations and the .45 packs so much of a punch
    the amount of rounds expended is relatively low.
    G-18 Machine Pistol
    Clip size: 33/6
    Weapon size: Small
    Pickup: 33
    Damage: Heavy
    Firing mode: Full automatic
    Description:  While small, the G-18 can really rip through enemies with its
    incredibly fast firing rate.  It can tear through even armoured enemies like a
    hungry hyena through fresh meat!  However, it runs out of ammo quickly and
    there aren't many enemies that carry it.  Save it for desperate situations or
    use it in conservative bursts.
    BIZ-2 Machine Pistol
    Clip size: 66/6
    Weapon size: Small
    Pickup: 66 (full clip)
    Damage: Medium-Heavy
    Firing mode: Full automatic
    Description: The BIZ-2 is a powerful, fast weapon that holds plenty of ammo. 
    Even with one clip, the BIZ-2 has enough firepower to take on a whole bunch of
    enemies.  Itís a good, all purpose weapon that can handle just about any
    situation.  Extra ammo isn't always common, but just one clip can last a while
    if used sparingly.
    HK-5 Machine Pistol
    Clip size: 32/6
    Weapon size: Small
    Pickup: 8 (SF1) or 16 (SF2)
    Damage: Medium-Heavy
    Firing mode:  Full automatic
    Description:  A good weapon to reach for in non-specialized situations, the
    HK-5 is a fast-firing, powerful machine pistol, although technically inferior
    to the BIZ-2 in ammunition capacity.  Usually, ammo from fallen enemies is
    common, so go ahead and unload on enemies.
    12 Gauge Shotgun
    Ammo capacity:  25
    Weapon size: Large
    Pickup: 5
    Damage: Heavy
    Firing mode:  Manual reload
    Description:  While it has obvious weaknesses, such as its slow firing rate,
    reduced (about half) damage at long range, and its small ammo capacity, the
    shotgun is an excellent weapon.  It loses effectiveness when used against large
    groups of enemies.
    Combat Shotgun (SF1 only)
    Ammo capacity:  30
    Weapon size: Large
    Pickup: 5
    Damage: Heavy
    Firing mode:  Manual reload
    Description:  The combat shotgun is surprisingly similar to the normal one,
    except that it holds 30 shells.  Treat it as the same weapon.
    UAS-12 Automatic Shotgun
    Ammo capacity: 12
    Pickup: ??
    Damage: Heavy
    Firing mode: Full automatic
    Description: The UAS-12 is a powerful automatic shotgun; while its firing rate
    is lower than most automatic weapons, it has the power of a 12-gauge.  Its main
    weakness is its small ammo capacity.
    PK-102 Assault Rifle
    Clip size: 30/6
    Weapon size: Large
    Pickup: 10 (SF1) or 15 (SF2)
    Damage: Medium
    Firing mode:  Fully automatic
    Description:  Like the M-16, the PK-102 is a good medium weapon for general
    use.  It has a good firing rate and can eliminate unarmoured enemies quickly. 
    However, ammo is not always abundant, so be careful with it.  It has about the
    same damage and firing rate as the M-16.
    M-16 Assault Rifle
    Clip size: 30/5
    Weapon size: Large
    Pickup: 15
    Damage: Medium
    Firing mode: Full automatic
    Description:  A good all-round weapon, the M16 has a pretty good firing rate,
    and has lots of ammo.  It makes a good main weapon to use for general purposes.
     In most situations where the M16 is available there are plenty of clips to be
    taken from enemies, so donít be afraid to use ammo.
    K3G4 Assault Rifle
    Clip size: 20/6
    Weapon size: Small
    Pickup: ??
    Damage:  Medium
    Firing mode:  Fully automatic
    Description:  The K3G4 fires special rounds that pierce flak jackets.  Itís
    useful for eliminating armoured enemies when you donít have time for head or
    leg shots, or when youíre badly wounded.  While it is technically an assault
    rifle, it has full a 360-degree firing arc.
    Sniper Rifle
    Clip size: 10/3
    Weapon size: Large
    Pickup: 10 (full clip)
    Damage: Low
    Firing mode:  Semi-automatic
    Description:  The sniper rifle has a zooming scope that can identify parts of a
    targetís body.  Despite this, itís still a weak weapon thatís really not
    useful.  Its scope is good for studying enemies up close, if you really need
    to.  If needed, it can be used in a fire-fight, but the even the 9mm is
    Nightvision Rifle
    Clip size: 10/3
    Weapon size: Large
    Pickup: 10 (full clip)
    Damage: Low
    Firing mode:  Semi-automatic
    Description:  The nightvision rifle is like the sniper rifle, without the fancy
    optical-recognition.  It has an infrared scope, so itís good for scouting out
    enemy positions.  Note that this weapon fires slower than the sniper rifle;
    avoid using it in dangerous situations.  It has a wider field of view than the
    sniper rifle in SF1, though the reverse is true in SF2.
    H11 Automatic Sniper Rifle (SF2 only)
    Clip size: 50/6
    Weapon size: Large
    Pickup: 50
    Damage: Medium
    Firing mode: Full automatic
    Description:  The H11 has an awesome firing rate that rivals the G-18 and a
    huge clip.  However, it fires low-calibre rounds that relatively little harm;
    however, because of its firing speed, it can match an assault rifle in actual
    damage.  The H11 also has a basic scope with crosshairs and limited zoom.
    Explosive/Gas Weapons:
    Incendiary Grenade:
    Max. Carried: 10
    Damage: Instant incineration/instant-kill shockwave
    Description:  This grenade explodes in a cloud of ammonium perchlorate, an
    inflammable substance.  It incinerates enemies and has a shockwave that will
    knock them over, but burns out quickly, meaning it wonít leave a smoking crater
    in the ground.  It has a delayed detonation of a few seconds.  This weapon has
    a large blast so be very careful.
    Soman Nerve Gas Grenade:
    Max. Carried: 10
    Damage: Unconsciousness, later death
    Description:  Unlike the incendiary grenade, this device releases a powerful
    nerve gas that stuns and eventually kills enemies.  Be careful not to gas
    yourself.  Gas grenades have no timer, they always explode on impact.
    M-79 Grenade Launcher
    Ammo Capacity: 15
    Weapon size: Small
    Pickup: 1
    Damage: Instant incineration/instant-kill shockwave
    Firing Mode:  Manual reload
    Description:  The M-79 is a powerful long-range grenade launcher that fires
    40mm fragmentation grenades.  The grenades explode on impact and have a rather
    large blast radius, making it a dangerous weapon to use in close quarters. 
    This weapon has a huge blast, so be very careful in close quarters.
    Ammo Capacity: 5
    Weapon size: Small
    Damage: Instant unconsciousness (can kill with head-shot)
    Description:  The crossbow fires a dart with a chemical payload that causes
    unconsciousness on contact.  Aiming for the head can result in killing the
    target.  This weapon has extremely limited ammunition and is never carried by
    enemy forces.
    Tear Gas Launcher:
    Ammo Capacity: 5
    Weapon Size: Small
    Pickup: 1
    Damage: Instant unconsciousnes
    Description: The tear gas launcher can be used to quickly neutralize multiple
    enemies quickly.  Special operatives are immune to the gas.  Gas cartridges
    explode on impact
    C4 Plastic Explosive:
    Damage:  Demolition
    Detonation mode: Timer or remote
    Description: C4 is only for special purposes, not for combat.  However, misuse
    can cause fatal accidents.  C4 is a very stable explosive; sharp maneuvering,
    weapon recoil and being shot will not cause an explosion.
    Special Weapons:
    Combat Knife (SF2 only)
    Weapon size: Small
    Damage: Instant-kill
    Description:  The combat knife is a very powerful weapon that can instantly
    kill an enemy, even one with a flak jacket.  It can only be used a point-blank
    range.  The best time to use it is when an enemy is distracted, reloading or
    between bursts.  Remember: Opportunity is one of the hyena's most potent
    Air Taser (Taser in SF1):
    Weapon size: Small
    Damage:  Delayed incineration
    Description:  The hi-tech equivalent of the bite-the-neck-and-shake-hard
    technique, the air taser shoots an electrocuted wire, which paralyzes enemies
    and eventually incinerates them.  It is completely blocked by flak jackets, but
    a leg or head shot negates this protection.  This weapon is a fire hazard, so
    be careful not to burn yourself.
    Taser (SF2 only):
    Weapon size: Small
    Damage: Instant unconsiousness
    Description: The taser is a close range weapon that can instantly drop an enemy
    with one touch.  It is not affected by flak jackets.  It replaces the knife in
    some missions, and should be used in the same way.
    SECTION 5	Specific Tactics:
    These tips will not make sense if you are not familiar with Syphon Filter
    games.  They are specific and often refer to the game mechanics.  The text
    assumes that you are familiar with the basics of Syphon Filter gameplay.
    When a weaponís clip (or chamber, etc.) is empty you will automatically reload.
     However, you can change clips when one is partially empty by pressing the
    Triangle button (assuming you use the default control configuration).  This is
    faster than the automatic reload and lets you have full ammo for the next
    encounter.  If a clip is ejected while it is not empty, it is not discarded,
    but returned to your extra ammo storage.
    In general, the closer you are to an enemy, the more likely you will be able to
    shoot it.  The reverse also applies; enemies will hit you more often when they
    get close.  Stepping in front of an enemy is likely to cause you damage to your
    flak jacket and possibly injury.
    Firing Backward and Sideways:
    Automatic aim allows you to not only fire forward, but to the sides and
    backwards.  Shooting sideways is a good tactic because you can run forward
    towards the next objective/checkpoint.  However, accuracy is decreased while
    firing in any direction other than forward, so donít expect great results.  You
    can also fire backwards, but only if you have a small weapon.  Weapons listed
    as small in SECTION 3 have full 360 degreee firing arcs.
    Manual Aim vs. Automatic Aim
    There are advantages and disadvantages to each aiming mode; you will likely
    need to know how to use both.  While using auto aim, you can move around while
    firing, and the Target meter lets you know how likely you are to hit your
    target.  You can also fire sideways and backwards.  However, auto-aiming points
    your weapon in the general direction of the target; it is not very accurate. 
    Manual aim has the advantage of being able to aim for specific parts of a
    target, such as the legs and the head.  It is also very accurate and almost
    guaranteed to hit what your crosshairs are pointing at.  Lining up a target
    with manual aim often caused increased damage to the target; more shots will
    hit the target and shotguns have their full effect.  Shooting an enemy with a
    shotgun at long range with auto-aim causes reduced damage, but with manual aim
    you can literally send the target flying.  You can also use the L2 and R2
    buttons to move to the side and back again with manual aim, utilized in the
    tactics discussed in the second section.
    Camera Angle
    Remember that you are not always facing the way that the camera is.  This is
    important in auto-aim mode, where the camera points towards whatever you have
    locked onto.  Make sure you are pointing directly at the target, especially
    when using a large weapon.
    Head Level Sweep
    To quickly take out enemies with flak jackets, try using manual aim at head
    level and ďsweepingĒ back and forth with an automatic weapon.  This is best
    done with a G18, which has an amazing firing rate, or the H11, which has a
    similar rate of fire.
    Ammo/Armour Balance:
    Remember that you should always aim to take more from enemies than you expend. 
    If you use a burst of five PK-102 bullets to kill an enemy soldier and take his
    ammo clip (10 shots), youíve gained 5 bullets.  Using a weak weapon, such as
    the 9mm, or using the taser, which never runs out, and gaining ammo for better
    weapons is usually worth the effort.  Also, if you take a hit fighting an
    armoured enemy, you should try to take its flak jacket to patch up your own.
    About the games:
    Q: Is there any real gameplay difference between Syphon Filter 1 and 2?
    A: There are some differences, such as weapons and some game engine quirks, but
    the core gameplay is the same in both games, which is why I wrote one guide for
    both games.  Here are some of the differences:
    -"shifting" to the side using the L2 and R2 buttons in conjunction with manual
    aiming mode causes taser problems in SF1
    -"shifting" is slower in SF1 than SF2
    -the weapons choices are different; see the weapons section for more info
    -the shotgun continues firing if you hold the button down in SF1
    -enemies will use head-shots in SF2
    -some of the sound effects are different
    -the HK-5 has a different appearance (possibly a different variation)
    -the 9mm is always silenced in SF1
    -the HK-5 is never silenced in SF1
    Q: Will unconscious enemies ever wake up?
    A: No.  They are effectively dead.
    Q: Is it possible to accidentally harm an ally if he/she steps into the line of
    A: Yes, it is possible.  Although allies will not be auto-targeted, be careful
    that they don't get between you and your target.  A hyena must be careful who
    it bites.
    Q:  Are there any glitches in the games?
    A:  Yes; the K3G4 and fuel hose leave flak jackets intact when they should have
    been destroyed, in SF1 you cannot shift to the side with manual aim and use the
    taser, the taser is SF1 breaks windows befores the wire even makes contact,
    trying to fire in manual aim results in a click when you are unarmed and
    sometimes there are odd graphic bugs.
    Q:  Sometimes there is a short cutscene when I use the knife on an enemy.  What
    causes this?
    A:  I've seen the cutscene in the third mission when enemies were distracted by
    an ally; as far as I know it means that the enemy was not targetting you and
    probably wasn't paying attention.  It's a classic hyena tactic: take down the
    target when someone else is distracting it.
    Q:  Usually getting shot damages my flak jacket, but one time I got hit by a
    burst with a fully intact jacket and I died immediately.  What happened?
    A:  At close range, many weapons are more powerful; in addition, automatic
    weapons hit more frequently, which can cause massive damage.  Either that, or
    you got hit with a G-18.
    Q:  Is there any way to save progress in the middle of a mission?
    A:  Yes, but only in SF2.  Highlight "Options" on the ACD and select "Save and
    quit game".
    Q:  Can I be hurt while using the ACD?
    A:  Yes and no.  If you press start to use your ACD, the game is paused and you
    can't be harmed.  If you press Triangle to recieve transmissions from another
    operative, enemies may surround you and open fire as soon as the transmission
    ends.  However, this is rare.
    Q:  Do you lose weapons after they're empty?
    A:  No, but they won't be selectable by just pressing Select; you must hold
    Select to open the weapons display or use your ACD's weapons info screen.  This
    is useful to know if you want to use the scopes on the nightvision and sniper
    rifles, but generally, selecting empty weapons is useless.
    About the guide:
    Q: Why does this guide cover both Syphon Filter 1 and 2?
    A: Syphon Filter 1 and 2 are basically parts of the same game; they run off the
    same engine with only minor variations, and SF2 continues the story of SF1. 
    The basics of gameplay are essentially the same; making two guides would mean
    repeated content.
    Q: Is this guide official?
    A: No.  This guide is not endorsed in any way by any of the corporations
    involved in creating, distributing, publishing or marketing Syphon Filter
    games.  All information here is based on the author's opinion and experience of
    the games.
    Q: What's with all the hyena stuff?
    A: Hyenas are very smart.  They know a lot about this kind of thing.  And
    they're fluffy.
