DOOM 3 Hints
Codes for Health and Items
NOTES: The word "spawn" can be used in place of "give" in most of the following codes. "Spawn" puts the item on the floor in front of you, and "give" puts it directly into your inventory. To give yourself more ammo for a particular weapon, just give yourself that weapon again.
* give all - get full health and armor plus all weapons with full ammo * give berserk - berserk mode * give ammo - max ammo * give health - max health * give armor - max armor * give weapons - get all weapons with zero ammo * give weapon_chainsaw - chainsaw * give weapon_flashlight - flashlight * give weapon_pistol - pistol * give weapon_shotgun - shotgun * give weapon_machinegun - machine gun * give weapon_chaingun - chaingun * give weapon_handgrenade - grenades * give weapon_plasmagun - plasma gun * give weapon_rocketlauncher - rocket launcher * give weapon_bfg - BFG * give weapon_soulcube - soulcube
The "spawn" command can also be used to give yourself adrenaline stims plus the megahealth and invisibility items that only exist in multiplayer. The megahealth works fine in single player, setting your health to 200, but the invisibility doesn't seem to work at all except to make what little you can see of yourself on-screen look hazy and transparent -- monsters will see you and attack just the same.
