Dungeon Keeper 2

Dungeon Keeper 2 is a strategy game developed by Bullfrog Productions and published by Electronic Arts in 1999 for Microsoft Windows. In the sequel to Dungeon Keeper, the player takes the role of a 'dungeon keeper', building and defending an underground dungeon from the would-be heroes that would invade it, as well as from other keepers. In the campaign mode, the player is charged with recovering the portal gems from each area in order to open a portal to the surface. The player can also construct a dungeon without strict objectives, and multiplayer is supported over a network.
