well, since it got deleted or something, I'm remaking this thread. When the game has been selected, got to options, then go to cheats, their type "i feel like s h i t" (no spaces in between the letters of that last word) this will unlock a zombie costume which, when equipped, will give you immortality. if you want immortality without the costume, type "king christian" this only works one time so you have to continuously type in the code
