Tips

Blind Luck

This is a very easy and simple way to unlock the Blind Luck achievement. After being vomited on by a Boomer, run back into a safe-room while hitting any zombies in your way. Shut the door and wait. Then, tah-dah, achievement unlocked.

Door Frame - No Mercy Finale

Note: this only works with four human players.

On the Finale on No Mercy where you call for help. There is a door behind you. Open it and there is a staircase. Two people stand at the top and the other two at the bottom. Shut the doors as this will by you a small bit of time. When the door breaks keep pressing LT. Make sure one of you is crouched and the other is standing behind. Its almost impossible to get constricted or pounced. Get out when you have to fight the tank, but rinse and repeat. Don't do it after killing the second Tank though.

easy Cr0wnd

To get this achievement(killing a witch in one headshot) make sure you have the standard shotgun. Autoshotty works best,though.

Run up behind the Witch while she is sobbing her heart out. As she starts to turn and stand up to face you, fire your shotgun when she looks like she is crouching like the survivors do. Make sure your crosshair is between her head and body(her neck pretty much, or where her hair touches her body). It takes ome time, but you too will be a Witch killer! Just wait till the Wizard hears about it...

expert witch

here is an easy way to kill a witch on expert because we all know how frustrated it makes us when there is a witch right in your path. okay when you see the witch turn off you light and make sure your team stays away from you. then you run up to the witch but not really close (requires auto shoty) then you shoot rapid fire on her. remember to have full ammo when you do this. their is another way but its a little bit harder but easier to understand. get close to the witch really close then shoot her and back up immediately and keep shooting her with the auto shoty and their we go. no more witch in the way.

metal door

on the third level of no mercy there is a bit where you have to start a lift and battle the horde.

instead of that there is a metal door opposite the lift. Hit that a few times and it will break down. go up the stairs and turn left to find a medical cabinet and then just continue as normal.

no mercy finale

on the finale of no mercy when you activate the radio you can go up the stairs and if you go to your right you will see barbed wire. if you go onto this barbed wire and quickly get over to the edge and jump onto the white phone looking thing all the zombies will glitch out and not know where to find you. also the tank will not spawn half the time and when he does spawn he will glitch out and not be able to get to you. it is recommended to do with 2 people because a smoker and hunter will always know where you are for some reason.

over the barrier

on the 4th level of death toll if you beat down the machine gun over and over again after a while you will be able to jump on it and it will give you an incredible boost in a jump. so on the barrier of the 4th level when it says to push the car down to start the alarm don't and instead you can jump over it if you do this tip.

Reloading

Reloading can be a pain. Especially when you have a horde after you and literally have no time at all for it. Luckily, there is a way around it. Once you need to reload, press X and either just start hitting zombies or switch to your pistol. This doesn't effect reloading, so when you take out your main gun, it will be reloaded and ready for use.

surviving a horde 101

in the second level of dead air you will have to activate the crane which will start a huge horde. grab a moltov and stay at the top where you started the crane. when you hear the horde coming throw the moltov at the big gap between the wall and the fence. all the zombies will go through the fire and die. but a few will get smart and start climbing the fence but dont worry about them your team will take them out. happy hunting!

Wall of PWN

Are you getting owned by the horde? Are you drowning in their sheer numbers? Have you ever wanted to punt a zombie? Well, now's your chance!


Whenever you activate a key moment(alert the horde,eg. The elevator), you'll be assaulted by an endless horde. Here is what to do. Find a corner of a room or area, and crouch there with one other teammate. Your other too must stand behind you, standing up. Now, you and your friend jam on them melee button as your friends shoot. Impenetrable wall! Except from Tanks and Smokers. Our testers are still working on that...Works in Versus and campaign.

Easy way to get the harder achivments.

This is an easy way to get some of the achievements in story mode. Have someone start a game. Have everyone except the person who started the game at the xbox dashboard. When the game starts stay in the saferoom. Invite the people in and have them accept the invites while they are at the dashboard. When they get into the game then the game will think they have played it all the through from the beginning. Its easier to get the expert ones doing this. But the person who hosted the game will not get the achievements for beating it on expert or for ex. Do Not Disturb. I found this to be very helpful.

extra clip suicide

Ok,this works off of any high building(make sure its after any safe room or youll have to start all over.) First, equip any kind of weapon ( shotgun, assault rifle ,etc..) get on top of a building and jump to your death. When you respawn you should have an extra clip of any weapon you had before you died..Example: The assault rifle holds 50 rounds...you will have another 50 added. Repeat.

Get Out of Dead Air Finale

Note that this glitch requires 2 players or more.

At the start of the Dead Air Finale go along that first platform and walk out the hole in the other side of the walkway. Go to the end of the walkway just outside of the safe house.

Now go up the little hill between the plane wing and the trashed plane, then have your two players press up against the boundry line and, one at a time, press take a break. Once this is done it will say "press right trigger to go out of idle". Press it and you will go back into gameplay on the other side of the boundary line.

The person on the other side of the boundary just needs to move back a couple of lengths while the other player is in idle and when they press right trigger they will be on the other side as well.

Note: if you want to go back lower your ammo and then go down the walkway beside the safe house walkway {the one over the boundary line}. Go all the way down the walkway then go idle and your player will teleport into the safe house.

Ghost slap

(works best with hunter because its slap damage is the highest at a 6)

In versus mode, when a special infected spawn and run far enough from survivors to the point where it will ask you to enter spawn mode again with the X button. Once far enough, press Left Trigger (Slap) and "X" (Despawn) at the same time. This should spawn you close to the survivors and carry over the slap and damaging them.

Does not work 100% of them time because you might not spawn exactly in the spot to hit them.

Hunters are the best choice because they run the fastest and can jump far out of the way of the survivors. Plus they do a slap damage of 6. Do this 5 times and you just did 30 damage.

If you do this with a smoker they will do 4 damage per slap.

if you do this with a boomer they will do 2 damage per slap.

I do not recommend doing this glitch. People will get pissed and file complaints on you.

GLITCHIN SOME PILLS HERE!!!

I tried this on offline multiplayer with a friend.

First, make sure you have pills, and your friend doesn't. Now, give them the pills. They have to hit the left shoulder button really fast, and so do you. After about 2-3 minutes of extremely fast pill swapping, stop. You and your friend should each be holding pills. Free pills! Now go get slaughtered by a Witch.

Infinite Pipe Bombs/Molotovs

Step 1: Have one pipe bomb in your inventory.
Step 2: Look at another pipe bomb.
Step 3: Take your pipe bomb out and press R.
Step 4: Before you let go of the pipe bomb pick up a new one.
Step 5: Throw pipe bomb.
Step 6: Pick up new pipe bomb(new one will respawn).
Step 7: Repeat step 5 and 6.
Note: You have to do this constantly. If you don't pick it up almost 2 seconds after you have thrown one the glitch will stop working.

Go up to a down surviver, and hold (X) and look at him. You should see a progress bar like you would when you pick up a fellow survivor like yourself. It should pick him up.

Safe

On survival mode on Blood Harvest the warehouse if you go into the middle of the room you start on and go to the right you will see a air conditioner and by it is boxes. Jump onto the boxes by jumping on the medal bar that holds them and then jump again. Then go to the corner of the boxes (upper right) and their should be a small gap and if you jump in that nothing can get you except for the occasional smoker.

Team Fortress 2 Teaser

In the apartment of the first level on No Mercy, look around the entire apartment. You will eventually find a box of "Chocobites" cereal. On the back of the box, it promises a free six-inch Team Fortress 2 action figure. That's pretty neat. The teaser, however, is where it says "Collect All 10!" at the bottom of the box. If you have ever played Team Fortress 2 then you know there are only 9 classes in TF2. Valve's Robin Walker has hinted towards adding another class to Team Fortress 2 in the past. After finding this Easter Egg, perhaps it could be coming a lot sooner then people think.
