idkfa 

A well-known cheat code for the computer games Doom and Doom 2. Entering the code gives the player all keys, all weapons, and full ammunition. It can be entered an unlimited number of times per level to refill ammo.

The cheat code most likely means:

id = id Software
k = keys
fa = full ammo

I can't believe they left the classic Doom cheat codes like idkfa and iddqd out of Doom 3!
