Dungeon Keeper

Dungeon Keeper is a strategy video game developed by Bullfrog Productions and released by Electronic Arts in June 1997 for MS-DOS and Windows 95. In Dungeon Keeper, the player builds and manages a dungeon and protects it from invading "hero" characters intent on to steal. collected treasures, killing monsters and ultimately the player's demise. The ultimate goal is to conquer the world by destroying the heroic forces and rival dungeon guardians in each realm. A character known as the Avatar (similar to the Avatar from Ultima VIII: Pagan) appears as the final hero. Dungeon Keeper uses Creative Technology's SoundFont technology to enhance the atmosphere. Multiplayer with up to four players is supported using a modem or over a local network.

Dungeon Keeper took over two years to develop and an expansion pack, a Direct3D version and a level editor were released. Midway through development, lead developer Peter Molyneux decided to leave Bullfrog when the game was completed, which was the motivation for its success. Versions for the Sega Saturn and Sony PlayStation were in development but were cancelled. The game received critical acclaim, with reviewers praising its uniqueness and depth. Dungeon Keeper was re-released on GOG.com in 2011 and on Origin in 2016. A fan-made mod, KeeperFX, has been released, which fixes bugs and adds features. Dungeon Keeper was followed by a sequel, Dungeon Keeper 2, in 1999, and influenced games such as Lego Rock Raiders and Ghost Master.
