In a world, (By world I mean the UK) where zombies run amok, they're ugly as hell, they don't like you, and they express violence by clawing, vomiting, shredding, screaming, shooting, igniting, biting, and killing you. But there's a lady who goes by "The Trader" who'll give you ♥♥♥♥ to blast the living spirits out of those suckers. There's gore, guns, money, but sometimes that's not enough. Since it's a UK game what would The Doctor do? Absolutely nothing. You're there, bored as hell. Then I descend from the heavens (my bed) to help you. My last guides for Team Fortress 2's MVM (Big success) and Left 4 Dead (A lot of dumb and negative feedback, still over 1,000 views), has helped, now for a non Valve game, one by Tripwire Studios, we're going into Killing Floor.

First off, you access the console with `.
Since this isn't a Valve game, the console works a bit differently, not using similar command words for TF2 or L4D.
THIS IS THE MOST IMPORTANT COMMAND Type "EnableCheats"
Incase you're the biggest wuss in the world and give up, type "Suicide" into console, Scaredypants.
"Behindview 1" will let you enter Thirdperson, and if you played 3D platformers, you should know what that means. You can turn it off with "Behindview 0"
"God" will make you invincible.
Wanna feel like you're on the moon, or in the vacuum of space, or getting slowly crushed by a trash compactor? "SetGravity *number*" will alter the gravity of everything.
Wanna turn a murderous funhouse into a murderous BOUNCE HOUSE? "Setjump *number*" will make you jump as high or as low as you want.
"Teleport" will make you teleport to where your crosshair is pointing.
You are very lonely. "backup" will spawn a bot, HOWEVER, it will not do anything, so toss him around if you'd like.
"loaded" will give you max ammo for all weapons. (Highest is 999)
"Phil" is godmode, don't know why, but it is. Phil must be powerful whoever he is.
"WinMatch" will make the match over, and make you winner for doing absolutely nothing, you lazy bum.
"Ghost" will enable Noclip.
"Fly" Will enable flight mode.
"Walk" will disable noclip/flight.

Wanna rob the seductive gun shop owner of everything? She's annoying, and says too many sexual things to get you to buy her things when you REALLY need them to survive UK's zombie apocalypse. So screw the Trader, the console gives away free stuff!

NOTE: Doing some of these commands will give you DLC weapons, even if you didn't buy the DLC, the items are still not purchasable from the Trader.

SMG: gives you all sub-machine guns
bombs: Gives all explosive weapons
Rifleme: Gives all Rifle weapons
Shotty: Gives all shotguns
Assaultme: Gives all Assault Rifles
Meds: Gives all Medic weapons
Pistols: Gives all Pistols
Meleeme: Gives all Melee weapons
Flameup: Gives all Fire weapons
Arsenal: Gives ALL the weapons. NOTE: This makes it very difficult to browse weapons.
