This is some codes for doom I have found out.

Just type them any time during the game

IDKFA----------Gives you all the wepons and cards

IDDQD----------Makes you invonerable.

IDSPISPOPD-----Makes you able to walk through walls and stuff

Heres one more to let you do alot more just play with it.

IDBEHOLD------ Gives you a menu at top with several choices.
