Record Gameplay

To record your gameplay using the Command Console, simply type in "Record" then a space and then any name you want it called. It will then record the gameplay. If you type in "Stop" in the CMD, it will stop recording. If you progress a level, the recording will stop and create a new file for the next map, adding an "_" and an integer (eg. "_02") to the end of the original file name. You can watch the recording at any time by typing in "playdemo" then a space and then the file name.

Tips

Easily Achieve Tank Achievements (With Cheats)

Would like to make a minor edit to it. I would like it to say this instead:

"Although this involves using the Command Console, it is a particularly easy way to obtain the Man Vs. Tank, Tank Buster and Towering Inferno Achievements all simlutaneously. Make sure to change the difficulty setting to Expert at first, and play on Campaign with all bots on your team. Start the first level of No Mercy, and shoot all your team mates until they are all incapacitated. Ensure that no Survivors manage to revive downed members. Afterwards, finish them off quickly. Change the difficulty back to Easy. Then, turn on cheats (sv_cheats 1) and spawn yourself a molotov (give molotov). Then, turn on noclip (noclip) and fly up to the rooftop just to the left of the door leading into the building your standing on top of. Land on that rooftop (noclip) and then spawn a tank, while looking directly onto the rooftop you started on before (z_spawn tank). WITHOUT leaving the command console just yet, turn off cheats (sv_cheats 0), then exit the command console. You should have a tank appear right in front of you by now. Quickly, throw a molotov at it and make sure it catches on fire. Then, simply walk as far as you can from the Tank while still remaining on the rooftop you're on, to ensure that the tank can't reach you or throw a piece of concrete at you. After a minute, the Tank should fall and you should receive your three acheivements!"

Get lost? Don't know where to go?

If you get lost, no idea to go anywhere, no clue at all. Simply find some crowd of zombie they will get you back on track. or find a rail truck and keep moving, and enable Full Caption on Settings to read the message from your teammates and your character.

killing the tank easily on vs ( recomended pc )

Running diagonally from the tank ( SD ) as he is charging toward you. just as he is close enough to hit, go opposite way ( WA ). you will be behind him. keep shooting and repeat. after about fifth time they get wise to it.

Pump Shotgun vs. Auto Shotgun

Basically, these two guns are the same damage wise, but the pump has a slower fire rate, so if a choice arises, go with the auto indefinitely.

Shot the Car in the First Level?

If you shot the car in the first level, the best thing you can do is take off down towards the safe point. And lock the door.

Tips on accomplishments

Couple ways to get the not so easy accomplishments:
Tank on Fire: When on the rooftop of the hospital, pick up the molotovs, and light an area around you on fire, and then attract the tanks attention.
Dead Stop: Use a shotgun and run at a Hunter hitting the melee button repeatedly.

Versus Mode: Hunter Wall Jumping

To jump off of the walls of buildings as a Hunter in Versus mode, simply crouch to charge your jump. Jump, then, as soon as you hit the wall, quickly turn your character around so that you're at least facing 180 degrees from your original point of view, before the Hunter begins to drop. Quickly click the mouse again, whilst still holding the crouch button, to propel yourself off the wall and further into the air.

This trick is useful for reaching higher places. It may take some practices to perfect.

Disfigured Zoey's Hand

On the campaign poster for No Mercy, Zoey's right hand, whilst holding the pistol, is disfigured, having formed a second hand off of it.

Fire an entire clip in 1 second

This will work with only the full auto guns, aka the Uzi submachine gun and the assault rifle. This works in 360 version and might work on PC.
  1. Equip the Handgun, hold down melee (LT) until you swing twice.
  2. While still holding down melee, switch to your full auto gun (Y) and hold down the fire button (RT).
  3. Keep holding down both LT and RT until you have held down RT for 7-10 seconds, then let go of LT only.
If done right, you will fire the entire full auto clip at once in a manner of 1 second, and the game registers as all the rounds being fired. This works really well for Tanks as long as you can hit them of course. If all 4 people can manage to do this on a Tank, he will be either dead or fairly close to dead within like 10 seconds.

Hunter Glitch - Silent and Run While Crouched

As a Hunter in "Ghost Mode" (Blue Screen), walk into an object that you can move through. ie. Crates, Doors. Press the crouch button for a a split second, and if done correctly, your view will be seemingly crouched and you fun twice as fast (while still in Ghost Mode). After you spawn, your Hunter is completely silent and will not be detected ("There's a Hunter over there!") by Survivors, as well as be able to run around. From this, you can pounce straight away without having to wait for your meter to build up. However, you can only pounce once, otherwise you will then fix up the glitch until you die and try it again in Ghost mode. The same goes for crouching again and jumping. You can still Melee, climb and walk off edges.

Reload whilst Meleeing

This trick has only been proven to work with either of the two shotguns, due to the fact that reloading cause the bullets to stack, and isn't reloaded with one single clip.
To perform the glitch, simply press the melee button as soon as you choose to reload. You character will initiate the melee action, which will knock the infected back, therefore cancelling the reload animation. Despite this, your gun will still continue reloading, making it much easier to keep yourself safe whilst reloading the shotgun.

Skip major portion of No Mercy: The Apartments

This is initiated at the very beginning of the first chapter in the first Campaign, No Mercy. Directly behind you at the start of the game is a ledge. Across the alley, on the building opposite, is an air-conditioning vent that can be reached by jumping off the ledge and landing on it. This will consumer roughly around half your character's health, but will skip a large portion of the gameplay that includes moving through the Apartments to reach the entrance.

Tank Buster Accomplishment

Sometimes, you'll run into a tank where you wouldn't usually expect it, and you can go places it can't, like vents. So, you could hide in a vent, and repeatedly shoot it, without it damaging you at all.

The Crane Survival Cheat

When you spawn in survival and look out to your left there is a truck on the road. Go down the the edge of the building behind were you spawned. Press space and hold and walk straight to the truck. You should land on the truck alive. You'll need a friend for the rest of the cheat. Your friend should start the crane and repeat what you did. He must try picking you up in mid-air. Press E when this happens. You and your friend should both be on the truck alive. Go to the edge of the truck that lead to the right of the building and jump off across the line from the closest building. If you fail you will die. If you made it go down the road in till you see the alley way. Go in and the infected shouldn't reach you. When your done with your goal in time just go outside and try getting on the truck.
