Dungeon Keeper 2 is a strategy game developed by Bullfrog Productions and published by Electronic Arts in 1999 for Microsoft Windows. 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 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. The game carries over many ideas from the original and adds new elements including units, rooms, and objectives. Development was carried out by a team of around fifty people, who focused on the graphics on multiplayer. A PlayStation version, and a sequel, Dungeon Keeper 3, were in development but cancelled. Dungeon Keeper 2 received positive reviews: reviewers lauded the graphics and artificial intelligence, although some reviewers criticized its similarity to the original. The game was later released on GOG.com and Origin.

An evil warrior known as the Horned Reaper (or "Horny") believes he has the ability to remove Portal Gems from Harmonia, and has enlisted the player's assistance in conquering its realms so he can claim the Portal Gems.

The kingdom itself takes the form of a large table containing a 3D map where the player selects where to attack from the highlighted regions. There are twenty main levels in the campaign.
