Literally every time someone says the words “Cheat Codes”, my brain says to me “IDDQD”. Then I answer it back with “IDKFA”. Cause I talk to my brain. Those are in there forever. Rent free.
Its more fun to use IDDQD and then IDCHOPPERS. you still have to play and find the keys/weapons but you get a chainsaw immediately. Running around invincible with a chainsaw is a good memory of that game for me.
