I've heard that there are a variety of cheat codes in both DOOM and DOOM 2, to allow things like all weapons, all keycards, walking through walls (no clipping) etc.

What are all of the cheat codes in DOOM?

Below are the cheat codes for DOOM (all versions) and DOOM 2

Godmode IDDQD
All weapons + key cards IDKFA
All weapons, no key cards IDFA
No clipping IDSPISPOPD (DOOM 1/Ultimate DOOM only)
No clipping (DOOM2) IDCLIP
Show all map IDDT
Warp to Level XX IDCLEVxx (In DOOM 1, this is (E)pisode,(M)ission ie 18 for episode 1 mission 8)

Use these codes to get specific items:

Give me a chainsaw! IDCHOPPERS
Give item X IDBEHOLDx (Where x = item code)
Give beserker IDBEHOLDS
Give invisibility IDBEHOLDI
Give invulnerability IDBEHOLDV
Give computer map IDBEHOLDA
Give radiation suit IDBEHOLDR
Give light amp goggles IDBEHOLDL

Most of the cheat codes between DOOM and DOOM 2 are the same, the only real difference is for the no clip code which is IDSPISPOPD in DOOM and IDCLIP in DOOM 2 and Final DOOM.
