                                     Left 4 Dead 2
                                   Versus Mode Guide
                                       Adam Haun
    To die, to sleep;
    To sleep, perchance to dream; ay, there's the rub.
    For in that sleep of death what dreams may come
    When we have shuffled off this mortal coil
    Must give us pause...
    Left 4 Dead 2 expands on the original co-op zombie shooter by adding new
    maps, characters, and gameplay elements. The centerpiece of the game is
    Versus mode, where two teams play as both survivors and infected, competing
    for points with the capricious AI Director acting as referee. The multiplayer
    aspect is both a blessing and a curse -- humans are more fun and challenging
    than any bot, but it's easy for one bad player to drag down a whole team.
    New players are often confused and overwhelmed by the fast-paced and highly
    competitive Versus mode, but without a single player or low-difficulty practice
    version it's hard for them to get better. After seeing a lot of people making
    the same basic mistakes I decided to write this guide to help out.
    What this guide will do
    I'll discuss basic techniques for playing as the survivors and as each
    of the special infected. I'll describe common situations and give suggestions
    for how to deal with them (and how not to deal with them). I'll also
    make sarcastic comments. These can be safely ignored.
    What this guide will not do
    I will not cover controls, basic game mechanics, or any other entry-level
    material unless it's specifically relevant to Versus mode. My assumption
    is that you've played the game in Campaign mode. Also, I will not provide
    walkthroughs for any of the maps, although I may refer to them as examples.
    Between the procedural content generation and the variability of human players
    there's no way I can tell you what to do in any specific location. Finally,
    I'm not going to give a lot of numbers for damage and recharge time. Numbers
    are very popular in FAQs but my experience is that Left 4 Dead benefits more
    from a qualitative understanding of gameplay. Maybe the exact numbers are
    important for serious clan folks, but if you're at that level you don't want
    me telling you how to play anyway. If you're a beginner, technique and timing
    are far more important than worrying about whether you're making a 20 or 25
    damage hunter pounce.
    I'm not a grandmaster and I don't play competitively, so I can't claim to
    know all the ins and outs of the game. If you see something that I'm missing,
    please feel free to email it to me using the address at the bottom of the FAQ.
    I don't need a ton of minutiae, though -- this is just to get people started
    so they can play without dragging down their team too much.

    Part I: Before You Play Versus
    Although there is no practice Versus mode, there are some things you can do to
    prepare for real play.
    I.A Play Campaign Mode
    This will help you learn the maps and practice playing as the survivors in a
    multiplayer setting. You should be able to beat all the campaigns on Advanced
    difficulty and make it through at least a few maps on Expert. While you're
    doing this, practice the following skills:
      * Shooting zombies while running
      * Identifying the special infected by sound and music
      * Quickly shooting a special infected off of another player
    Versus mode differs from Campaign in many ways. Here are some of the more
    important ones:
      * Difficulty is locked to Normal.
      * Special infected spawn continuously from the moment the survivors walk
        out of the safe room door.
      * Survivors cannot respawn after dying except with a defibrillator.
      * In each round the survivors start fresh with full health and a pistol.
      * The score is based only on distance traveled with special infected damage
        acting as a tiebreaker. Ending the round with higher health offers no
      * Four special infected can attack at once.
      * Each map is randomized only once. Both teams will encounter the same items
        and witch and tank positions while playing as survivors. However, the
        number and position of the common infected and the timing of random horde
        attacks will still vary.
      * Play is much faster. In Campaign mode you can take your time and thoroughly
        clean and search each area, but in Versus this is often a death sentence
        since you'll constantly be under attack.
    I.B Listen to the Developer Commentary
    Optional but highly recommended, this will give you background info on a lot
    of the gameplay elements and may draw your attention to things you didn't
    notice before. It's also a good way to familiarize yourself with the Parish
    I.C Learn to Talk
    Communication is extra-important in Versus. One of the keys to victory is
    coordinating with your team. The best way to do this is with a microphone,
    but if you're a fast typist the keyboard can work too. Good times to talk to
    your team include but are definitely not limited to:
      * Hearing a special infected
      * Getting attacked by a special infected
      * Moving away from the group
      * Planning a crescendo event
      * Moving through a one-way barrier
      * Planning a coordinated special infected attack
    Part II: The Easy Part -- Playing as the Survivors
    II.A Overview
    The goal of the survivor team is to get as many points as possible by moving
    as far as possible through the map without dying. Reaching the safe room is
    worth 25 bonus points per survivor. Backtracking cannot hurt your score except
    by taking away your safe room bonus if you die.
    To work together, the survivors must deal with conflicting needs:
      Need #1: Stick together to avoid ambush and better fight the infected
      Need #2: Keep moving to score points and minimize the time spent taking
               damage in each area
    A team that stays close while running quickly through the map is almost
    invincible. A team that meanders around and has to keep backtracking to
    rescue attacked players is doomed. Different players have different skill
    levels and strategies (e.g. explore for items vs. rush), which makes
    coordination difficult.
    II.B General Techniques
    Most of the same techniques used in Campaign mode still apply. The emphasis
    in Versus is on speed and mobility.
    II.B.1 Follow the Leader
    Pick another survivor (hopefully someone who knows what they're doing) and
    stay near them. Don't run off on your own initiative. Do shoot zombies and
    special infected when you get the chance -- just don't take too long. This
    is the simplest technique for beginners but is still useful since it keeps
    you from being a good target for the special infected.
    II.B.2 Run and Gun
    Run through the map, shooting zombies as you pass them without stopping.
    As they take slightly different paths, the survivors will tend to spread
    out in a line. The rear player has the most risk and the most responsibility,
    since they're both the biggest target for the special infected and the one
    best positioned to shoot any zombies chasing the group. Unfortunately, this
    is where less skilled players tend to end up. The front player is only slightly
    better off -- they get to pick the path, but have to make sure that everyone
    is keeping up.
    This technique works best with a tight group of players moving through a fairly
    small number of zombies. The special infected are at their weakest when they
    have to chase the survivors, so by the time they spawn you want to already be
    past them. The downside is that it's easy to get separated and surprises
    like tanks and witches can catch the players in a bad position. As always,
    communication is the key -- if you get left behind or have a special infected
    running at you, say so.
    When someone says "Let's rush!", this is what they want to do.
    II.B.3 Stand Your Ground
    Stand near the other survivors (no more than a medium-sized room length apart)
    and shoot at whatever threatens you. This is typically used to deal with a
    horde or tank. Players may move around as they shoot (if it's a tank) or stand
    completely still (if it's a horde running down a long narrow pathway). This
    formation has the highest offensive and defensive power. The special infected
    can easily get into position for an attack, but no attack can last long against
    concentrated firepower.
    The downside of this technique is that it involves taking damage without
    helping your score. An uncoordinated team that hangs around too long can suffer
    through multiple rounds of special infected attacks. To avoid this, move out
    of the area the moment the existing threat is gone.
    When someone runs into a room and says "Come in here, everyone!", this is
    what they want to do.
    II.B.4 Using Grenades
    Grenades are best used on common infected, just as in Campaign mode. The
    exception is the tank, on whom molotovs and boomer bile both work well.
    Pipe bombs are especially helpful for run and gun while molotovs are best
    for standing your ground. Pipe bombs and bile are great when you need a
    distraction so you can pick up a fallen comrade or make it to an escape
    It's hard to find a bad use for grenades but it's easy to find bad teamwork.
    Be sure to tell your team when you find an extra grenade, and announce over
    the mic when you're throwing one. It's very common for two players to throw
    a pipe bomb at the same time. Try to have both molotovs and pipe bombs in
    your team's inventory.
    Note that since Versus uses Normal difficulty damage, running through a molotov
    won't hurt you very much. This can be helpful if you're surrounded by a horde.
    II.B.5 Healing
    Ammo belongs to the individual, but health belongs to the team. Give your
    pills and adrenaline to whoever has the least health, and don't hesitate to
    use your healthpack to heal a teammate -- they'll return the favor. An
    injured survivor is a magnet for the special infected, and a knockdown
    means one less person to help against an attack.
    The flip side of this is that health is a precious resource and must not
    be wasted. Don't heal until your health bar is red, or preferably until
    you've already been knocked down once. Healing in yellow is usually a waste.
    Don't leave any healthpacks or pills behind. Sometimes I see people at half
    health pass up pills because they already have some. Don't do this -- take the
    pills you have and grab the extra bottle. The only time it's okay to ignore
    healing items is when you're just out of the safe room and everyone's at
    more than 85% health. Try to time your healing so that it happens right
    before or after a major event. Here are some good times to heal (even when
    you're in yellow health):
      * Before a crescendo event
      * When you first hear a tank approaching (for mobility)
      * When you're too slow to keep up with a run and gun
      * After you've been knocked down twice and your screen is black and white
    A healing survivor is a target for the infected, so try to heal out of sight
    in small rooms or around corners. If your health is very low (<15), the special
    infected may try to run up and slash at you to put you on the ground without
    needing a special attack.
    II.B.6 Weapon Choice
    A player's choice of weapons doesn't seem to make a lot of difference, so
    use whatever you're comfortable with. Sniper rifles are rarer in Versus
    because your team should never stop to snipe, but they're not unheard of.
    Likewise, melee vs. pistols is left to your preference. Melee users should
    be careful about blocking the line of fire by running into a horde of zombies.
    The exception to all this is the grenade launcher, whose high friendly fire
    damage and slow reload time tend to do more harm than good. I'm not a grenade
    master, though, so maybe you can find a good use for it.
    Don't go crazy with friendly fire, but don't be afraid of it, either,
    especially when shooting at special infected or a horde of zombies surrounding
    another survivor.
    II.B.7 Right-Click Push
    Click the right mouse button to push away zombies, knock off hunters and
    jockeys, and disconnect smoker tongues. This is the fastest way to stop
    a special infected attack, and if you lack a melee weapon it's a requirement
    when you're surrounded by a horde. It's pretty simple, but remember that
    pushing an infected away doesn't kill it. I've seen people push a hunter
    off another survivor and then take a quarter health bar of damage because
    they never bothered to actually shoot it. Unless you're in the middle of
    an attack where half-seconds count or you're reloading and won't be able
    to attack for a while it's usually better to shoot special infected instead
    of pushing them.
    There are a couple situations that especially benefit from pushing. Hitting
    a teammate ensnared in a smoker's tongue frees them instantly, which is great
    if they're being pulled off a roof or if it would take a few seconds to shoot
    the tongue. In a run and gun, pushing zombies keeps them from getting in front
    of you and makes them easier to target. Also, if the survivors have an infected
    surrounded they can push it to death and avoid friendly fire damage.
    Note that the push doesn't work on the charger, tank, or witch.
    II.B.8 Flee for Points
    In many games, there comes a point where you know your team is doomed. You're
    widely separated, three of you are knocked down, and a horde of zombies is on
    its way. The only thing left is to maximize your points by sprinting towards
    the end of the map. Don't worry about saving your pills and grenades and
    don't stop to use a healthpack -- the only thing that can save you is raw
    speed. The special infected will be hot on your heels, so watch behind you.
    Smokers are usually instant death. Hunters, chargers, and jockeys can be
    dodged and killed. Boomers and spitters are more easily evaded. Pretend
    you're Rambo -- it helps. Skilled players can sometimes make it through the
    last third of the map and into the safe room all by themselves.
    More rarely, two players may flee together. This works best when the special
    infected are still tied up with the downed survivors -- perhaps a smoker and
    a jockey pulled them off a roof and have yet to drain their health bars. Two
    players are much more likely to succeed, especially if they get lucky with
    which special infected spawn.
    Abandoning your team is not something to do lightly. Unless there's a
    compelling reason to do so, you will piss off your teammates and may end
    up on the receiving end of a kick vote. If there's no horde or tank and
    the other players are all in line of sight, go ahead and pick them up.
    II.B.9 Falling Down and Getting Up Again
    A knockdown is a critical event for the entire team. Four active survivors
    can fight off most infected attacks, but three are much more vulnerable and
    two are almost certain to fall to a special infected attack. Thus, it's
    important to get downed teammates on their feet as quickly as possible.
    If a common (but not special!) infected hits the downed survivor in mid-pickup,
    the pickup timer will reset, so clear the area first if possible. If not,
    pipe bombs, boomer bile, and even a boomed teammate make great distractions.
    In a tight space your teammates should surround you while you lift.
    Urgency aside, your first priority should still be to rescue teammates from
    special infected attacks. Don't make them wait several seconds before you
    start coming after them.
    If you get knocked down, don't just sit there twiddling your thumbs. Shoot
    any zombies you can and keep an eye out for special infected. Your pistol
    can make the difference between a live team and a dead one if the teammate
    helping you up gets pounced by a smoker. You can't shoot very accurately but
    you can do at least some damage to nearby opponents.
    II.C Dealing with the Infected
    Each type of special infected has its own quirks, but one thing they all have
    in common is noise. The moment an infected spawns it makes a characteristic
    sound, and it will continue making noise until it dies. Each infected also has
    a distinctive silhouette which is visible at long range. The special infected
    move much faster and more directly than the common infected. If you pay
    attention to what you see and hear you can often kill the special infected
    before they get a chance to attack. Another auditory cue is music -- each
    infected has its own theme music that blends in with the overall soundtrack.
    If you learn to identify the songs you can sometimes tell which infected are
    coming up.
    Obviously you'll want to stop a special infected attack as soon as possible.
    Sometimes you can leave it to a teammate, but as a general rule if two or
    more teammates are attacked at once you should *instantly* move to assist.
    II.C.1 Common Infected
    On Normal difficulty the common (and uncommon) infected (aka zombies) do
    very little damage. As such, they act more like terrain than anything else.
    If there are few zombies, you can move quickly through the map. If there are
    lots, you have to go more slowly. A random horde can hold you still for 30
    seconds or so. Common infected can help the special infected by boosting their
    attack damage. Aside from that, they're not much of a challenge unless you're
    on your own and surrounded by a huge horde.
    II.C.2 Hunter
    The hunter is not very hard to deal with. It mostly attacks in conjunction
    with other special infected, although a long-distance pounce can do decent
    damage on its own. Like all the special infected, hunters are most threatening
    to a player on their own. If one pounces a teammate, shoot it immediately since
    the pounce damage builds up quickly. If a hunter is trying to pounce you, run
    back and forth perpendicular to the pounces -- any lag will favor you. The
    timing is tricky but it is possible to block a pounce with the right-click
    push. It's easier to push a hunter after a near miss, so jam on the right
    mouse button if you can't line up a shot. Once you push, be sure to go for
    the kill since the hunter can quickly recover and slash at you.
    Hunters often move long distances by jumping. Some players will try to reach
    high places or do acrobatics. If you're lucky you'll be able to see the jumping
    hunter against the sky and shoot it before it can threaten you. Even a grounded
    hunter will sometimes poke its head out, so watch above you for a chance to
    shoot first.
    II.C.3 Smoker
    The smoker a bit more interesting than the hunter due to its ability to drag
    the survivors around. Watch for it when moving across high places and around
    corners. The smoker attack itself does less damage but the auto-aim and range
    make it very reliable. Its weakness is the tongue -- once it immobilizes a
    survivor, the smoker must wait a long time for its tongue to recharge. This
    gives the survivors an opportunity to hunt it down or run ahead. Without its
    tongue the smoker is very little threat.
    There is a trick for dealing with the tongue. When it hits, you have a couple
    seconds before you're immobilized. During this time you can try to shoot the
    smoker or (if you're close enough) push it to break the attack. Aside from
    that, your best bet is to stay away from ledges as much as possible to avoid
    making yourself a target. As mentioned above, you can push ensnared survivors
    to free them. If you can't reach them, shoot the tongue or the smoker.
    II.C.4 Boomer
    The boomer's main weakness is that it has to attack at close range. Boomers
    like to hide around corners and through doorway. If you hear a boomer doing
    this, shoot it through the wall. Skilled players will spawn close to the
    survivors and immediately try to attack, but there's always a brief window
    between hearing them and being vomited on. If you run around a corner and
    into a boomer, don't shoot it! Instead, push it away, then stand back and
    shoot. In tight spaces it can be hard to get the whole team away, but one
    vomited survivor is better than four. Be careful with the pushing -- if
    you do it too many times the boomer will explode.
    If you get vomited on ("boomed"), try to get to a wall or corner to make
    it easier to fight the horde. A helpful teammate may stand in front of you
    to protect you so be careful not to fill them full of lead. Booms tend to
    precede combo attacks, so listen for your teammates' cries for help. If your
    whole team gets boomed you might want to throw a molotov or pipe bomb to
    distract the horde while you stumble around fighting the special infected.
    I've found that having a large, high-resolution monitor makes it much easier
    to see through the bile, but I play on a 19" CRT so I'm blind for several
    seconds afterwards. :-(
    II.C.5 Spitter
    The spitter is a big threat under the right circumstances and harmless the
    rest of the time. The right circumstances (for the spitter, anyway) are when
    one or more survivors are immobilized. This happens during horde attacks,
    when helping someone up, when under attack from another special infected, when
    healing, etc. In all cases, your response should be the same -- immediately
    stop what you're doing and get out of the spit. Unless you are really
    truly seriously no bullshit one single second away from finishing that pickup,
    sticking around for the exponentially increasing damage will knock off a
    quarter health bar at best and put you on the ground at worst. It's easier to
    avoid the spit if you don't get backed into a corner. Also, note that a fallen
    survivor just inside the spit can be picked up by a player standing just
    outside the spit without either taking damage.
    The neon green glow of the spitter is very visible even at long range. If you
    hear the sound of a spit attack, take a moment to look around and shoot the
    spitter if you see it. The spit recharges fairly quickly, so you don't want
    to leave a live spitter around if you can avoid it (unless the person playing
    the spitter sucks, but we'll consider that an advanced technique).
    II.C.6 Charger
    The charger is a big damage dealer with high hit points. It can't be pushed,
    so you'll have to kill it to stop it. Oddly, the charger's charge is not as
    dangerous as it could be since lag makes it very hard to connect with. However,
    once charged a survivor will take damage very quickly, so kill the charger
    fast! At close range the punch is a serious threat, so counter with a melee
    attack or a clip full of bullets.
    The charge is most dangerous in narrow corridors. Try to stay behind obstacles
    or near a corner so you can dodge. As with the hunter, move perpendicularly.
    A miss leaves the charger vulnerable for a few seconds. Be extra careful near
    the edge of a death drop like the Hard Rain boat dock or the Parish bridge
    finale -- the charger can knock a survivor right off to an instant death. The
    Dead Center hotel windows are particularly nasty in this regard, so be on guard
    any time you hear a charger there.
    II.C.7 Jockey
    Like the spitter, the jockey isn't much of a threat on its own. Its attack does
    relatively little damage even over long periods of time. It's easy to shoot
    or push. But in combination with the other special infected, the jockey is
    deadly. Five seconds on a survivor's head can be enough to maneuver around a
    corner, over a ledge, or into a puddle of spit. It's hard to chase a jockey
    when you're under attack, so try to shoot it quickly. Remember that many walls
    can be shot through, so if the jockey makes it around a corner it doesn't
    necessarily mean you have to follow. Keep an eye out for jockeys in places
    like the window ledges of the first Dead Center map. A successful leap there
    is an instant knockdown since it only takes a moment to go over the edge.
    Jockeys have a long recharge time, so if you push one off you can kill it at
    your leisure. Surprisingly, one of the better methods for stopping jockey
    attacks is to stand your ground and shoot. Often you can kill it before it
    jumps, and even if it connects your teammates will only need a few bullets
    to finish it off. If you'd rather not get hit at all you can use a dodge
    then push method just like with the hunter.
    If a teammate gets pounced by a jockey, don't slowly chase after them with a
    melee weapon -- pull out your gun and shoot. It's much nicer for the victim.
    II.C.8 Tank
    The tank is the single biggest threat you can face in a map. That being said,
    it can be dealt with if you keep your cool and work together. The most
    important thing when fighting a tank is speed. Survivors in green health can
    outrun the tank. Survivors in yellow and red health can't. The moment you
    hear the tank music, check your health and heal or get ready to use pills if
    necessary. If the tank hits you once you'll probably fly into a nearby wall
    and get hit again before you can move. This usually ends with you on the
    ground. Tanks tend to focus on one survivor at a time so watch for an
    opportunity to pick up a downed teammate.
    If you're all in good health in a wide open area you can probably kill a
    charging tank just by dodging and shooting. Under ideal conditions, a good
    team can do this in 20-30 seconds. You probably won't have ideal conditions,
    so start by setting the tank on fire with a molotov or gas can. Note that
    incendiary rounds only set the tank on fire briefly. Fire damages the tank
    slowly and forces it to charge you. Start shooting. If the tank focuses on
    you, concentrate on not getting hit. If you need to, just turn around and
    run while your teammates shoot. If you can't set the tank on fire it may
    stay back and throw rocks to buy time until the other special infected can
    spawn. Try to snipe it. Don't forget that you can shoot the rocks out of
    the air. Trying to run past a tank is usually a bad idea since the new
    zombies will hinder your movement. 
    The biggest danger when fighting a tank is the other special infected.
    If your team gets boomed it's usually all over since the horde will prevent
    you from running. Even a hunter or smoker can hold a survivor still long
    enough for the tank to get in a hit. Watch above and behind you so you can
    catch them the moment they spawn. Try not to leave the line of sight of
    your teammates.
    Although the tank spawn location is roughly the same for both teams, it does
    vary a little bit. It seems like the second team gets it a bit later, although
    I'm not totally sure about that. This difference can make or break your team's
    chances, so be sure to take advantage of it if it happens.
    II.C.9 Witch
    As with the tank, the other special infected are often a greater danger than
    the witch herself. Still, a one-hit knockdown is nothing to trifle with. The
    witch is not very sensitive to bullets whizzing past her, so don't hesitate
    to carefully shoot a smoker standing behind her. Don't forget to turn your
    flashlight off.
    There are three common methods for dealing with a witch. The first is to avoid
    her by running past. Obviously this is easier if there's a lot of room but
    even in a tight space you can usually avoid startling her. Move quickly, stay
    together, and don't get caught fighting infected. If avoiding the witch isn't
    possible, you'll have to kill her. One way to do this is by "crowning" her --
    shooting her in the head with a shotgun. This needs to be done at very close
    range. I don't use the shotguns much so I can't offer a lot of advice (maybe
    someone will send me suggestions). Reader David Atkinson suggests aiming at
    the neck with an auto-shotty and going full auto until she dies. In any case,
    running up to crown a witch is a great time for special infected to attack,
    so be careful.
    The final method is just to shoot the witch to death. This method has a couple
    variants. One is to shoot from a long enough range that you can kill her before
    she reaches you. Another is to offer up a survivor as a sacrificial lamb. It's
    better if the lamb has low health to start with. Once the lamb is down the
    witch will start doing a lot of damage, so kill her quickly. This is another
    good time for special infected to attack. Be sure to kill the witch before you
    go after anyone else. Note that if the survivor who startles the witch dies,
    the witch will flee the scene without attacking anyone else, so don't bother
    shooting anymore.
    Part III: The Hard Part -- Playing as the Infected
    III.A Overview
    The goal of the special infected is to stop the survivors from earning points.
    The only way to do this is to kill them before they reach the safe room at the
    end of the map. This requires the infected to deal with three realities:
      Reality #1: Special infected are easily killed by survivors
      Reality #2: An infected acting alone is unlikely to do much damage
      Reality #3: Coordinated attacks must be timed precisely in order to work
    Winning as the survivors requires speed, but winning as the infected requires
    timing and precision. There will be long periods of time where you're waiting
    to spawn or attack interspersed with brief moments of opportunity. Survivors
    can kill an attacking special infected in as little as one second. Coordinated
    attacks against a prepared team are thus very hard to pull off. The key is to
    use distractions and positioning to your advantage. If one survivor is around
    a corner and the other three are fighting zombies, attacking the isolated one
    will result in much more damage. Likewise, if a random horde distracts the
    survivors you may be able to approach undetected. If no opportunities appear
    on their own, you'll have to work together to create some.
    III.B General Techniques
    Versus uses a very different set of controls and gameplay mechanics than
    Campaign mode and thus requires a different set of skills. Since there's
    no single-player practice for the special infected, you'll have to practice
    your techniques in a real game. What you can do in advance is learn the maps,
    which always helps.
    III.B.1 Situational Awareness
    Special infected can see each other and any moving survivors from anywhere
    in the map. Use this to your advantage. Are the survivors close together
    or strung out? Is one of them running off to explore? Are they nearing a
    terrain obstacle like a corner or doorway? Are any of them healing? Pushing
    a button to start a crescendo event? Shooting at distant zombies? What is
    your team doing? Is anyone getting ready to attack? Can you help them? Note
    that the halo around a stationary survivor will fade out after several seconds,
    so try to remember where they were. It's rare, but sometimes a clever survivor
    will turn the tables and try to ambush you.
    Pay attention to the info at the bottom of the screen and in the score window
    (hit tab). On the infected side, you can see who's controlling which infected,
    whether they've spawned (solid icon) or not (blinking icon). The circular gauge
    shows whether their special attack has recharged, so you know (for example) not
    to create a distraction for a boomer that can't vomit. You can also see how
    much time is left before your teammates respawn. In the score menu you can see
    the health of the survivors as well as which items they have. Pay attention to
    grenades and health, especially when you're the tank. If you don't want to
    look around you can tell whether someone's immobilized by an infected attack
    by watching their health go down.
    Sometimes scouting ahead of the survivors can be helpful. You can find witches,
    health, and large numbers of stationary zombies. If you're near a survivor
    who gets picked up off the floor, listen to the dialogue to hear whether
    they're near death ("white-screened" or "black and white"). You should be
    keeping track of knockdowns anyway but sometimes you forget.
    Keep an eye out for idle players ("AFKs") on both teams. Unspawned infected
    standing still a long way from the survivors are usually AFK. Try to talk to
    them, and if they don't respond, call a kick vote. It's very important to have
    four active infected, and going AFK without saying anything is rude. On the
    survivor team, an AFK is a golden opportunity to do some damage. You may choose
    to forgo it in order to be polite, but I haven't heard people get offended
    by such attacks. A good approach is to attack the non-AFKs and/or spit on
    the AFK.
    III.B.2 Spawning
    Spawning should usually be avoided until you're ready to attack. It slows your
    movement, costs you a lot of tactical flexibility, and starts making noise.
    One exception is if you're planning to attack from somewhere that doesn't
    have a convenient place to spawn. Unless you're a smoker, it's usually better
    to spawn ahead of or above the survivors. The infected are at their weakest
    when they have to chase the survivors from behind.
    You'll need to be out of the line of sight of the survivors behind opaque
    objects (not bushes). It would be nice if Valve would fix it so bushes count,
    but this is what we're stuck with for now. Usually if you put your nose up
    against an object and can see that all the survivor halos are behind it you
    can spawn. You'll also need to be at least several feet away from the nearest
    survivor, but this usually isn't a problem unless you're trying to spawn
    right next to them. Sometimes an object doesn't completely hide you, in which
    case you may have to duck or jump to spawn (yes, you can spawn in midair).
    In general, as you get closer to the survivors it becomes harder to spawn but
    easier to attack. With experience you'll learn the best hiding places and
    ambush spots. When you're in a hurry (e.g. following up on an attack) you'll
    want to spawn as close as possible to maximize your attack damage.
    III.B.3 Choosing a Target and Timing an Attack
    It's rare (although far from unheard of!) to knock down all the survivors in
    the first attack, so you'll have to wear them down. It's helpful to think of
    this in terms of intermediate short-term goals, such as:
      * Force the survivors to backtrack
      * Force the survivors to stand still and take damage
      * Knock down a survivor
      * Force the survivors to use up their healing items
      * Reduce all survivors' health bars to low levels
      * Kill a single survivor
      * Finish off the survivor team by attacking multiple members at once
      * Create a good tactical situation for doing any of the above
    There are two basic reasons to attack -- to deal damage and to set up for
    someone else to deal damage. If you're not going to accomplish either of
    these, don't attack! Leaping into the middle of the survivors to deal five
    points of damage and get killed in two seconds is a waste. But don't wait
    too long for the perfect opportunity or you'll never get anywhere. Balancing
    this takes experience. Sometimes (particularly against a skilled survivor
    team), there is no good course of action, and all you can hope for is to
    do a little damage and throw them off balance a bit. I rate attacks like this:
      Damage             Value
      <1/8 health bar    Bad attack
      ~1/8 health bar    Mediocre attack
      ~1/4 health bar    Worthwhile attack
      ~1/2 health bar    Good attack
      >1/2 health bar    Excellent attack
    Dealing damage takes time. Isolated survivors are usually the best targets
    for this reason. Don't take this too literally -- it's best if there's no
    help in line of sight, but things like hordes and tanks that take attention
    away from attacks are also isolating factors. Watch for survivors who ignore
    teammates in peril, too. AI-controlled survivors ("bots") have wacky
    situational awareness -- you can often move near them for a bit without
    getting shot, but they're undistractable and will instantly notice when
    you immobilize another survivor and will move to help. This can be a big
    advantage for the survivors, but the bots' premature healing and inability
    to be cheap is their downfall.
    All things being equal, you'll often want to attack the survivor with the
    lowest health. Damaged survivors slow down their team and give you a chance
    for a knockdown at an opportune moment. All things are rarely equal. For
    example, a downed survivor is weak and keeps their team from moving away.
    This is a valuable tactical situation. It's better to do a bit less damage
    and keep the survivor down (allowing your teammates to respawn) than it is
    to do a bit more damage and let them get away. Likewise, it may be better
    to attack a healthy survivor than a weakened one who's about to be taken
    down by a horde anyway.
    I can't cover every situation, but the list below should give you a basic
    idea of how to assign value to attack opportunities. Keep in mind that this
    will be affected by things like items (defibrillator?), location (right outside
    the safe room?), infected type (spitter, boomer), etc., so don't try to
    memorize it or anything. (Not that you were planning to do that, of course.)
    Target value (high to low)
      !!!! Last survivor standing
      !!!! Survivor about to die
      !!!! Survivor on the wrong side of a one-way passage (unstoppable kill)
      !!!  Extremely isolated survivor
      !!!  Survivor that will go down in a couple hits
      !!!  Survivor helping another survivor off the ground
      !!   Survivor about to attack another special infected
      !!   Isolated survivor during horde attack
      !!   Healthy survivor during tank attack
      !!   Survivor using a health pack
      !!   Survivor whose teammates have been boomed
      !    Slightly isolated survivor (around corner, etc.)
      !    Survivor under attack by horde
      !    Injured survivor surrounded by other survivors
      0    Healthy survivor surrounded by other healthy survivors
    III.B.4 Right-Click Slash
    Every infected aside from the tank has a secondary melee attack. When you
    click the right mouse button, you'll slash at whoever's in front of you.
    This is one of the most underused attacks in Versus, which is a shame because
    it's tremendously useful. The right-click slash has these advantages:
      * Very fast
      * Doesn't immobilize you
      * Doesn't need to recharge
      * Reliable targeting
      * A few hits does a worthwhile amount of damage
      * Can be used to do extra damage against an immobilized survivor
    If a survivor's health is near zero, you can run up, slash them to knock them
    down, then use your primary attack on a neighboring survivor, immobilizing
    two at once. If you get really lucky you can slash down two survivors and
    primary a third! This can make the difference between a weak team and a
    crippled team.
    Being pushed by survivors is very frustrating. Wouldn't you like to strike
    back? Jam on the right mouse button and you might get in an extra hit or two.
    Hold down the left or right movement key while you do this and if the survivor
    doesn't hit fast enough you'll start circle strafing and slashing the hell
    out of them! Survivors who have trouble aiming or don't know how to push can
    easily lose a third of their health bar this way. Against a skilled team, you
    might do more damage without the noise and visual cues of a primary attack.
    If a survivor is trying to push through a horde you can run up behind them
    and slash them -- they won't notice you because they're already being hit
    from all sides. If you're a hunter or charger and don't want to risk hitting
    the wrong target with a primary attack, you can use the right-click slash for
    guaranteed accuracy.
    It takes three slashes to break down a door. If a horde is pounding on a door,
    give them a hand!
    III.C Infected-Specific Techniques
    The original Left 4 Dead focused on the basic trio of damage dealing (hunter),
    separation (smoker), and delay (boomer). The gameplay was fun and fairly
    simple, but suffered from problems with survivor camping and limited attack
    options. L4D2 adds three new infected to address these issues and broaden
    the gameplay. The increased complexity makes it more important than ever to
    be aware of your role in the team.
    Like I said in the introduction, I'm not going to give numerical stats for
    the infected because I think a qualitative understanding is more important.
    The numbers are out there on the net if you want them.
    III.C.1 Hunter
    Role: Direct damage
    Health: Medium
    Attack power: Medium
    Attack speed: Medium-Fast
    Immobilizes: Yes
    Movement speed: Fast
    The hunter's job is simple -- hurt the survivors at close range. The range
    is the tricky part. New players like to leap into the middle of a survivor
    team and die one second later. Don't do this. Instead, watch for isolated
    survivors or stage a combo attack with your team. Remember, your attack is
    only worthwhile if it lasts for more than a couple seconds. Note that the
    hunter screams as soon as its attack charges, so hold off on crouching until
    the last second if you're trying to ambush someone.
    If you pounce from a longer distance you'll do more damage -- I think up
    to 25. I wouldn't bother with this until you're more advanced since it's very
    easy to miss. The hunter suffers greatly from lag. I'm not sure why this
    is. The client-side prediction may favor the survivors or it may be something
    else. In any case, pouncing moving survivors is difficult since you'll tend
    to sail past them or bounce off. It's not uncommon to end up jumping in
    circles around someone while they shoot at you. If this happens, consider
    running (or jumping) away. The hunter moves fast and has a short charge
    time so a retreat won't cripple you like it can with the other infected.
    Lazier survivors will stop your attack by pushing instead of shooting,
    which can give another opportunity for flight.
    Hunters are less visible than the other infected, and also run quickly.
    This makes it easier to sneak up and right-click slash the survivors.
    The slash is also useful when attacking someone who's behind a downed
    survivor since the hitboxes make it almost impossible to attack the back
    survivor in practice. Speaking of downed survivors, be careful -- they
    can you shoot you off a target after you've pounced.
    III.C.2 Smoker
    Role: Break up the survivor team
    Health: Medium-Low
    Attack power: Medium-Low
    Attack speed: Fast
    Immobilizes: Yes
    Movement speed: Medium
    The smoker's job is to separate one survivor from the pack. Smokers don't
    deal much damage early in their attack, so to be effective you have to do
    one of two things -- drag the survivor to where you can hurt them at leisure,
    or force them to backtrack and waste more time. The latter option includes
    things like pulling the survivor off a ledge or ladder. Ideally this will be
    part of a combo attack that forces the entire team to rescue their ensnared
    friend. The best attack (and the hardest to pull off) involves trapping a
    survivor on the wrong side of a one-way passage such as a drop or elevator
    door. This is usually an instant kill, so be sure to try for it whenever
    you get the chance.
    The smoker is not cut out for close range combat. Try to attack from around
    corners or behind cover to keep from getting shot. The tongue can take a
    moment to lock on, so don't be in too much of a hurry to click the mouse
    Note that the hunter, charger, and jockey can all break your attack with their
    own. It's very common in smoker/hunter combo attacks for the smoker to grab
    someone and then have the hunter inadvertently tackle them while aiming for
    someone else. It's often better to let the hunter go first, although this can
    make the timing more difficult.
    The smoker can pull survivors into an alarmed car or a witch, so be sure to set
    up next to one if you get the chance.
    III.C.3 Boomer (and Common Infected)
    Role: Hold the survivor team still / Distraction
    Health: Very Low
    Attack power: Low
    Attack speed: Medium-Slow
    Immobilizes: No
    Movement speed: Slow
    The boomer's job is twofold -- keep the survivors in the arena longer (causing
    them to take more damage) and set up for attacks from the other infected. The
    best way to do this is to cover as many survivors as possible in bile. The key
    limitations of the boomer are its slow speed, low health, short range, and
    distinctive noise. Unless they're spectacularly stupid, charging the survivors
    from a distance is out of the question. Getting boomed isn't just dangerous,
    it's also annoying, so the survivors will be on guard the moment they hear you.
    You'll have to be fast and clever. Successful boomer attacks are generally
    divided into two stages:
    Stage 1: Ambush. In this stage your goal is to vomit on the survivors. The
    vomit attack takes a second to work, so you'll need to avoid getting shot or
    pushed. Attacking from above works well (survivors rarely look up). On the
    ground, spawn behind an obstacle or corner, run out, and start spraying. It
    works best when the survivors are clustered, but sometimes you can only get
    one or two. Bile doesn't fly in a straight light, so aim up a bit to hit
    targets farther away. Bullets can go through most walls, so standing still
    and hiding will probably get you killed. Remember, the survivors can hear you,
    and they *will* be listening.
    Stage 2: Suicide Bomber. It takes longer to recharge the vomit attack than it
    does to respawn, so don't bother waiting -- charge in. In this stage your goal
    is to explode on any unboomed survivors while doing whatever you can to damage
    and disorient the rest. Odds are you'll get shot as soon as you vomit, but if
    you don't, you can right-click slash blinded opponents or walk into someone's
    line of fire. You might get pushed around, but if you're lucky one of the
    pushes will kill you. Explosions are more disorienting than vomit because they
    change the survivor's camera angle. Whatever you do, don't get left behind.
    Chasing the survivors across the map wastes time and rarely accomplishes
    As I said before, the common infected are like terrain in that they determine
    the speed at which the survivors can move. Most of them will be inactive and
    die without doing any damage. Only when the common infected swarm do they pose
    a real threat in terms of damage and mobility. Be sure not to draw them away
    from a good target -- booming a standing survivor can allow a fallen one to
    be picked up more easily!
    III.C.4 Spitter
    Role: Area denial
    Health: Low
    Attack power: Varies
    Attack speed: Slow
    Immobilizes: No
    Movement speed: Medium
    There is a very common misunderstanding about the spitter. I'm going to correct
    this right up front in all caps so you can't possibly miss it:
    The spit is an area damage attack that takes a few seconds to ramp up to doing
    serious damage. In L4D1 it was very common for the survivors to all back into
    a corner and camp during horde attacks. The spitter was introduced to counter
    this. Thus, the spit is only useful against opponents who are *not moving*. I
    see a lot of people try to snipe moving targets with the spitter. It never
    works. The survivors take two points of damage, and if the infected team is
    unlucky the spitter survives to screw up again. Don't do this unless you're
    about to die anyway.
    The best time to spit is when the survivors are held still -- usually by the
    common infected. A major horde attack or tight spot can keep the survivors in
    the same area long enough to take decent damage. A hunter, smoker, or (more
    commonly) jockey can force a survivor into the spit. In this case, the spit
    will add extra damage to the normal attack but not as much as it does on its
    own. There's really not much else to this -- if the survivors stand in the
    spit for a while, they get hurt. If they don't, they don't.
    Another use for the spit is to block a pathway. Survivors don't like running
    through spit and will usually wait for it to fade out, which can hold them in
    a room for a few seconds. This is rarely useful, though. A more interesting
    use is to detonate gas cans. This is especially helpful in the Dead Center
    finale. If the survivors throw gas cans down to the lower level, spit on them
    and in a few seconds they'll burst into flames!
    The spit recharges fairly fast, so it's a good idea to try to stay alive and
    spit several times (unless you suck, in which case, try a couple times and then
    die so someone else can have a turn).
    III.C.5 Charger
    Role: Direct damage / Break up the survivor team
    Health: Medium-High
    Attack power: Medium-High
    Attack speed: Medium-Fast
    Immobilizes: Yes
    Movement speed: Medium
    As with the spitter, there's a very common misunderstanding about the charger.
    Here we go with the caps again:
    The charger is a very versatile infected whose overall purpose is to attack
    tightly grouped yet mobile survivor teams. Its primary attack is the charge,
    in which it runs forward in a straight line, grabs the first survivor it hits,
    and sends any others flying like bowling pins. When it hits an obstacle, it
    begins smashing the captive survivor, doing lots of damage. A lot of people
    try to use the charge as a reverse smoker attack, but this is a bad idea since
    the charger doesn't auto-aim. What you want to do is go *through* the survivor
    team, hopefully knocking them over in the process so you have time to deal
    damage while your teammates attack. This is best accomplished in a narrow
    corridor like the path to the gun shop in Dead Center or the motel balconies
    in Dark Carnival. Out in the open it's very hard to connect with the charge,
    even at close range. You have to aim a little ahead of the survivor since the
    lag compensation doesn't handle the charge correctly. It's probably not worth
    trying unless you desperately want to immobilize someone -- you probably won't
    get a second chance if you screw up. Sometimes if all the survivors are in a
    corner you can knock them all over, but this is somewhat rare.
    Another use for the charge is to knock someone off of a ledge. This is tricky
    to pull off, but in some cases it's an instant and permanent kill if you
    succeed. The best and most well-known example is the hotel windows in Dead
    Center, but it's also common in the bridge finale at the end of The Parish.
    The charger has a very powerful secondary attack which is often more useful
    than the charge. Since the charger can't be pushed and has lots of health
    you can mix it up with a survivor, circle strafing and punching until they
    kill you. It's not uncommon to do half a health bar of damage if you catch
    them at the right moment. If you save your charge you can sometimes do combo
    attacks -- punch a weakened survivor down, then charge off with another one.
    The charger's Achilles heel is explosive ammo. It breaks your charge and keeps
    you from punching effectively. Be aware of what kind of weapon upgrades the
    survivors have!
    III.C.6 Jockey
    Role: Break up the survivor team
    Health: Medium
    Attack power: Low
    Attack speed: Medium
    Immobilizes: Yes
    Movement speed: Medium
    The jockey's job, like the smoker's, is to separate one survivor from the
    group. This is done using a short-range leap attack which mounts you on
    the survivor's shoulders and lets you steer them around with the movement
    keys. Most people seem to instinctively know how to play the jockey -- I guess
    there's not much else you can do with it. In case it wasn't obvious, the goal
    is to steer your target as far away as possible, or better yet off a ledge.
    Start by heading around the nearest corner or drop to keep the survivors from
    shooting you right away, then go wherever you can. This is great for punishing
    a lagging survivor -- their team will have to go twice as far to regroup.
    The jockey excels in combo attacks with the other infected. A boomer or tank
    can provide enough distraction to let you grab a survivor without being
    noticed. You can also guard an immobilized survivor -- when someone comes to
    rescue them, jump the would-be hero and move away. Now there are two people
    to rescue!
    Unfortunately, the jockey doesn't do much damage on its own, and once it's
    pushed off a survivor the leap takes a while to recharge. Also, the jockey
    makes a *very* noticeable high-pitched whinnying noise. This is just something
    you'll have to accept -- against a solid and attentive team the jockey is
    not very useful. You'll have to rely on your team and the Director to create
    opportunities for you.
    III.C.7 Tank
    Role: Direct damage / Hold the survivor team still
    Health: Very high
    Attack power: High
    Attack speed: Medium
    Immobilizes: No
    Movement speed: Medium
    The tank's job is to kill the entire survivor team. How easy this is depends
    on the health and weapon loadout of the survivors, the presence of common
    infected, what kind of support you get from your team, and the layout of the
    map. For something that's basically a giant slow-moving common infected (which
    is how Valve wants you to use it), the tank can be surprisingly hard to play.
    The biggest difficulty is the fact that a survivor in green health runs faster
    than you do. This leads to two options for using the tank.
    The first and most obvious option is to charge the survivor team and start
    swinging. If their health is low, you shouldn't have much trouble. This works
    best when the survivors are held still by common infected, so the boomer is
    your best friend. Go for the ones with lowest health first for a quick
    knockdown. Don't chase one survivor too far away or the others will regroup
    and come after you. Against a healthy survivor team, this strategy is suicide.
    They'll keep a medium distance and shoot the hell out of you while you run
    around looking like an idiot. For extra embarrassment they may swarm you with
    melee weapons. Running into this situation is a common newbie mistake -- don't
    do it. Sometimes there's no choice, in which case you might do a little damage
    by using the rock throw, which is hard to dodge at close range. You can also
    try hiding behind walls and obstacles until some eager survivor gets too close.
    The second option is to hide on a roof and throw rocks. The main advantage of
    this is that the survivors probably won't try to move ahead while you're still
    alive. This gives your team more time to spawn and do damage, or better yet
    boom the survivors. Have I mentioned that the boomer is your best friend?
    Because it is. Anyway, I'm not a rock master so I don't have any special kung
    fu for this strategy. Reader Michael Mair suggests that while the tank is
    picking up the rock you should aim away from the target, then turn to face
    them at the last minute to catch them off-guard. Players do tend to get close
    to the tank if they don't think it's aiming at them.
    Regardless of what you do, the first thing the survivors do will be to try to
    set you on fire. Unless you're playing Hard Rain and have a convenient source
    of water to put you out, you'll have maybe 30-45 seconds before you die minus
    whatever other damage you take. This means you'll have to charge. Obviously you
    should try not to get set on fire, but sometimes it happens before you take
    control of the tank.
    III.C.8 Witch
    Health: Medium-High
    Attack power: Very high
    Attack speed: Medium-Slow
    Immobilizes: Yes (through instant incapacitation)
    Movement speed: Medium
    The witch's job is to knock down a single survivor. "But wait," I hear you
    say, "the witch isn't a playable character!".  This is true, but she's still
    part of your team. Think of her as a newbie who just needs a little bit of
    help. Or maybe a land mine. Anyway, you should always notice and locate the
    witch before the survivors do. Your goal is to get the survivors to move near
    or shoot the witch without killing her, then follow up on her attack. You can
    do this by forcing them to move (smoker, charger, jockey) or standing in front
    of her to act as bait (hunter) or making them shoot nearby (boomer).
    The survivors will often attempt to "crown" the witch by shooting her in the
    head at close range. Interrupting this attack will likely startle the witch.
    There's not much else to the witch, really. She's pretty straightforward.
