These are cheat codes that will give you non-legitimate powers. To activate a cheat code, you must simply type the letters in order directly on your keyboard, then a message will show with the effect.

  • idbeholds - free berserk pack
  • idchoppers - add chainsaw
  • iddqd - invulnerability that will not expire
