For the Creature Spell, see Time Bomb (Creature Spell).
Time Bomb is a Keeper Spell cut from Dungeon Keeper. It still exists in the game's code, and can be added to maps or researched if files are edited to do so, and a spellbook is created as normal, labelled Time Bomb, but has the graphic for Conceal Monster. It cannot be used ingame, as there is no slot for it due to all 16 slots being used for the standard spells already.
It was unknown for a long time what Timebomb could've done, but in this interview with Simon Carter, the lead programmer of the game, he says:
"Until about 30 seconds ago I thought Timebomb was in the shipping game. Since it isn't, I'll tell you - you could turn imps into suicide bombers. Great fun!"
How this would've worked ingame is unknown. Reasons why it was cut could include it being seen as offensive (disappointingly enough, it would have fit perfectly with the game's twisted humor and atmosphere), or just it making the game unbalanced by making Imps more powerful.
