Dungeon Keeper Wiki

The Iron Door (known as the Steel Door in Dungeon Keeper 2) is the strongest door in terms of defence in Dungeon Keeper and Dungeon Keeper 2. It is also a door type in Dungeon Keeper Online.

Dungeon Keeper[]

The Iron Door is considered the best all-purpose door, and is first available to the player in Tickle. It has the highest natural defence and takes considerable time to destroy, but also requires considerable time and a relatively large Workshop to create. The Iron Door’s decent amount of protection from damage makes it one of the most suitable defences for nearly every situation, and usually allows enough time for a Keeper to gather their forces before it is destroyed.

In KeeperFX, a Ghost has a special ability that allows it to pass through the door, even if it is locked.

Dungeon Keeper 2[]

Just as it is in Dungeon Keeper, the Steel Door is the strongest door your workers can manufacture. When possible, use Steel Doors to keep your dungeon fortified and protected from any would-be intruders.

Hero Steel Door[]

In certain Campaign, Multiplayer and Skirmish maps, there will be hero fortifications guarded by their own Steel Doors. These doors look noticeably different, being of a portcullis style instead of a thick steel.
