Left 4 dead aimbot hack. If you are looking for glitches that can help you to complete levels faster, go check out some speed running websites. Another good thing about cheating in L4D2 is that since there is only very little emphasis on PvP, the chances of you annoying other players is greatly diminished, which is what we like to see. Since cheating in this game is not as open to abuse as in other games, the developers are not going as actively after cheaters. Cheating in L4D2 is of course the use of any kind of method, exploit or software that can give you an advantage and is not part of the official game toolkit and rules. The most commonly used cheats for the coop campaign and multiplayer modes are aimbots, that means software that automatically aims for you, and ESP hacks that will display all the friendly and enemy positions to you.

Mind control suicide While controlling someone else's mind, click Left Analog-stick + Right Analog-stick.

For the mind control suicide to work, you must hold Left Analog-stick + Right Analog-stick for several seconds. After awhile, the enemy will start to kneel. After he kneels, you can exit his body, but he will still commit suicide. Levitate yourself To levitate yourself in a way, get on to an object that you can levitate, such as a box. Aim down and hold Y to lock on. Press L, and the box will levitate with you on it.

To go higher, keep holding Y and press L continuously at the correct time. You should get progressively higher.

This is useful for getting to high and far places. In order to levitate from the ground, stand on any object such as a crate, barrel, bench, etc. Perform the TK ability while standing on the object.

Make sure that the crosshair is lined on the object. You will begin to levitate with the object with the Right analog-stick as if you were controlling an object from afar. Make sure that the object is not a wooden crate or an explosive barrel, as they are fragile to gunfire and other objects. This tactic can be used to make the 'drop' on enemies below. The only problem is that you cannot use any other mind powers.

Psi Ops Save

Instant kill To instantly kill someone with a shotgun without having to aim at their head, use TK to levitate them as high as possible without multi levitating. Walk almost, if not directly under them, and fire the shotgun. It should automatically aim at their head and blast it off. More Psi energy Sneak up on an guard and use the Mind Drain power.

You can almost fill your Psi bar up when it is completely empty. Anytime you get to a checkpoint and are short on health or energy, save the game. Reload it to get full health and energy. You can also simply Mind Drain anyone to regain Psi Energy. You need to have at least a little Psi energy for this to work, or enough to get someone on their back.

Use Telekinesis to throw him down and Mind Drain when he is about to get up. If you want a more gruesome death, wait until he is just about to get up and his head will pop, just like an ordinary Mind Drain at the end. If you cannot sneak up to an enemy and drain him, throw him at a wall, object, or the ground.

When he starts to get up, use Mind Drain. This will almost fill you Psi Energy completely if you are empty. Special skin abilities Some of the character skins have special abilities. For example, there are masters of Psi powers such as Barret, Pyro, and Lenov. They can do many more things than Nick with their powers. If you were to unlock their skins, you will also get those abilities. Edgar Barret: Can carry all MPs, has the ability to carry very heavy objects (boxcars, trains, crates, etc.; preferably in the Barret boss fight), Psi drains slower than usual.

Jov Lenov: Can Mind Control anyone, can make anyone commit suicide at anytime, Psi drains slower than usual. Marlena Pyro Skin: Her Pyrokinesis can burn faster, fire goes through most objects or until it hits a wall, Psi drains slower. The General Skin: Has all the powers listed above. Mainframe code On the level where you fight Jov Leanov, the code for to get into the mainframe is '2963'. Elevator music On the level with Wei Lu, while you are in the elevator the music playing sounds like 'With My Mind' by Cold.

Defeating Jov Lenov - Master of Mind Control TK the MPs that Lenov is MCing and throw them at the machines. After you destroy all of the machines, Lenov will fight you. Just use your gun or TK the MPs and throw them at him. Defeating Edgar Barret - Master of Telekinesis TK the objects on the conveyor belt and throw them at Barret.

After you get his health down a bit, he will take the fight outdoors. Just do the same thing until you defeat him. Watch out when he throws the large crates and boxcars at you. They can kill you in one hit if you are not careful.

Wait until he rests, then nail him. Defeating Wei Lu - Master of Illusion Use PK on the statues then shoot them. After you destroy all the statues, Wei Lu will transform into a huge three-headed dragon. Destroy all three heads to defeat her. It is best to go to the back of the room and use the assault rifle if possible.

Defeating Marlena Kessler - Master of Pyrokinesis Use TK to pick up and throw the canisters at the large gun. To avoid the huge blast, go to the back of the room.

You will notice some glass things that popped out of the floor. Get behind one of them. Once you destroy the huge weapon, Marlena will fight you. TK the canisters and throw them at her to defeat her. Note: The canisters will refill after you use them all (they must all explode). Also, make sure you are on the side that she is on. Defeating Nicholas Wrightson - Master of Remote Viewing Destroy all the screens in the room to defeat Wrightson.

You can only destroy them when they are firing. Just dodge the ray and shoot them. Be sure to also, avoid the Aura Beasts in the room. Defeating The General - Leader of The Movement Use PK on each Monolith pillar (the spinning things). Upon destroying them you can collect up to six orbs (which will be scattered around the room) for your new psionic weapon.

Once The General gets to full health, the fight will begin. Just shoot him with the psionic weapon to damage him. You can refill your psionic weapon's ammunition by getting in the center of the Monolith. Note: Make sure to quickly get out from the Monolith once your ammunition is refilled.

Also, when The General goes invisible, just use your Aura View to see him. Defeating Zombies If you have a shotgun, just shoot them in the head. If not, MC one with a shotgun and use him.
