Classic cheat code
from the ID software
. Typing it gives the player all key
s and full ammo
There are several proposed meanings for KFA, such as "Keys Full Ammo" or "Kick Fucking Ass". Personally I doubt any suggestion that does not interpret the K as "Key", since the code idfa
has the same effect, except that it does not give the player the keys.
The code has the same effect in Doom II. Using it in the follow-up game Heretic gives the response "cheater - you don't deserve weapons" and disarms the player. If you really want to cheat in Heretic you should use "rambo" instead.
