The Tank



The Tank is a huge, muscular Infected capable of throwing large items such as cars or blocks of concrete. The tank keeps a high profile, able to be heard by the Survivors from a great distance due to its loud thrashing while running. The immense strength and toughness of the tank makes it a terrible foe in combat. Special walls on some maps will be outlined with yellow cracks (similar to the paws on climbable objects) to indicate that the player can break through the wall as a special infected. To prevent the tank from camping away from the survivors for too long, a frustration timer is set when the survivors are not in sight. When the timer runs out, the tank becomes uncontrollable and begins stomping and thrashing giving away its position and becoming vulnerable to the survivors. If this happens to the human while he is playing as the Tank, although the selection of the Tank is random, the computer will give control of the tank to another player. If the second player's timer runs out, the computer regains control. He is one of two Boss Infected, with the other being the Witch. There is normally 1 Tank per round, though the Director can add another one if the Survivors stall. Finales usually have 3: 2 during the 10 minute wait, and 1 more when the rescue vehicle arrives.

Survivors

 * Listen carefully for the tank, make sure you can distinguish him from a hunter/smoker/boomer. By the time the tank is in your line of sight, it is often too late to plan an effective defense. In fact, upon hearing the tank, some players may want to simply try to hide until the meter builds and then while the computer is thrashing, run from the noises.
 * Throw a Molotov cocktail in its path to set it on fire and slowly eat away at its life. Fire damage is independent of the Tank's hitpoints, and will assuredly take down a Tank after a duration dependent on the difficulty level. The Tank lasts 30/30/35/40 seconds for each difficulty (Easy/Normal/Adv./Expert). This method ensures a Tank death if you are unsure of your ability to down the beast with firepower.
 * If the tank is very close, focus entirely on running away. If there are no obstacles, run backwards so that you can shoot on the run. A Survivor with sufficient health can outrun the Tank. Otherwise, go ahead and open up on it. Be aware that the nearest survivor that shoots the tank is the target.
 * If you are lucky enough to be near a thick tree, you can lead the Tank a merry dance by keeping the trunk in between yourself and him. He can't go over a tree and he can't rip it up either. In fact, any static physics object can allow you to avoid the tank.
 * The Tank can knock down the beginning saferoom door! Do not try to hide in the beginning saferoom when a tank comes, use the tactics above instead.
 * The tank climbs obstacles much more slowly that he can run; exploiting this fact will provide you with more uninterrupted firing time.
 * If you are incapacitated and the tank is not on you, do not shy from using pistols on the tank since every bit counts. If you are incapacitated and the tank is on you, stop firing immediately because it prevents your friends from distracting him. If you are still alive when the tank is distracted, a friend can help you back up and you can resume the shooting. Dead, you will be of no help.
 * If you're in an area where falling is possible, such as the Rooftop Finale, make absolutely sure that you are between something solid and the Tank, so that the massive knock back from its attacks doesn't launch you on an incredible 30 story journey to your death.
 * Generally, you need 51% health (green health bar) according to the Left 4 Dead Xbox manual, though less is required on maps with obstacles to block the Tank.

How to deal with ranged attack
 * The tank can't move and throw.
 * You'll know when he's doing a throw by the absence of the ground pounding noise.
 * Anyone can shoot the concrete out of the air, rendering it harmless with any weapon.
 * The tank can predict where a survivor will run, if it's an AI. Zigzagging will avoid the rock.
 * Non-static geometry such as crates will not block his shots.
 * You may be unable to dodge a rock if you are limping too badly (i.e.: when your health bar is red or yellow).

Infected

 * Even though the tank was made to charge through seas of lead, a strong survivor team can take him out with no damage taken.
 * Avoid attacking in the open if at all possible.
 * Use alternative routes where possible to "sneak up" on the survivors.
 * Use concrete projectiles to knock down pesky marathon survivors.
 * If you incapacitate a survivor, immediately re-target on another. Wait a few seconds, and then go back to the first incapacitated survivor to knock-down the foolish medic helping the first survivor back up.
 * If playing on a rooftop level such as chapters 4 and 5 of the No Mercy campaign, do everything you can to knock survivors off the building, as this will kill them instantly.
 * If you are on fire, water will put it out.
 * Tanks can punch cars and dumpsters large distances.
 * A hit by car or dumpster instantly incapacitates a survivor.
 * Hitting cars is faster than throwing concrete.
 * Punch survivors in different directions to separate them.
 * If the survivors are indoors, keep attacking one survivor (choose the one with the lowest health first) till they are knocked down and need assistance to get up.
 * Be careful using the swing attack on survivors in wide open flat areas as this merely gives them a chance to get away. Charge a survivor you've whacked as soon as you whack him.
 * Always aim to divide and conquer if you're in a building or in an area with lots of objects in it. Try to spread the survivors out by hitting them behind large objects or knocking them out of windows.
 * If the survivors can't see you, they can't shoot at you, meaning that you will take less damage during your rampage.
 * This helps hunters to pounce on survivors, or smokers to grab survivors, so they can't come to the group's aid or the group coming to kill the infected that has them pinned or tied up, leaving you with one less survivor to kill.
