Dungeon Keeper is a strategy video game developed by Bullfrog Productions under Peter Molyneux and released by Electronic Arts in July 1997 for the PC in which the player attempts to build and manage a dungeon or lair while protecting it from invading 'hero' characters intent on stealing the player's accumulated treasures and killing various monsters. This was Molyneux's final project with Bullfrog before he left the company in August 1997 to form Lionhead Studios.
The player uses a mouse, represented in-game as a hand, to interact with a bar on the left-hand side of the screen, allowing them to select which rooms to build and which spells to cast. The player can also use the hand to pick up creatures and objects in the dungeon and carry them around, allowing for tactics such as gathering an assault force and dropping off the creatures en masse once a foothold has been established. The hand also allows the player to "slap" objects and thereby interact with them: creatures will hurry up when slapped, some traps will be triggered and prisoners in the Torture Chamber can be tortured.
The main game view is in isometric perspective; this view can be zoomed and rotated. The player also has the option of possessing one of their creatures, and seeing the dungeon from that creature's first-person perspective, as well as using their attacks and abilities. The map is divided into a grid of rectangles, most of which are invisible. A smaller part of the map is shown as a minimap in the top left corner of the screen.
A world map is also available, and at the beginning of the game the player is allocated one of the 20 regions of a fictional, idyllic country to destroy. As the player progresses through these regions, each of which represents a level of the game, the areas previously conquered will appear ransacked, twisted, and evil. Before starting a new level, the Mentor (voiced by Richard Ridings) will tell the player about the current region and its attributes. After completing a level, the Mentor will talk about the "improvement" of the destroyed region: "The streets run with the blood of the slain. Screams of pain and howls of anguish rip the night air like a vengeful siren's song. This really is somewhere you can take the kids for the weekend."
The Dungeon Heart represents the Dungeon Keeper's own link to the world. If it is destroyed, the player loses the level, and must restart. Along with the heart, the player begins with a small number of imps, the generic work force for all dungeon activities: they can dig tunnels into the surrounding soil, capture enemy rooms and Portals, mine gold and gems, set traps, and even attack when desperate or threatened. Slapping creatures forces them to work faster for a while, but removes some of their health and happiness.
Once the Imps are busily working, the player must then set up a basic infrastructure: Lairs for monsters, a Hatchery (where chickens, which serve as food for the minions, are bred), and a Treasury for storing gold. After connecting the dungeon to a "Portal", monsters will arrive. The types of monster that will arrive depends on the rooms possessed, and how large they are: the Bile Demon, for example, requires both a Lair and a Hatchery of at least 25 (5×5) units. As the game progresses, the player moves along a technology tree, unlocking further rooms.
Some creatures are only accessible through special means. Creating a Prison room and leaving friendly or enemy creatures in it will result in Skeletons. Having an enemy or friendly creature die in a Torture Chamber will result in a Ghost. Dead enemies taken to a Graveyard room will result in a Vampire being born (although it is possible to attract Vampires through the Portal in some levels).
The strongest creature is the Avatar (appears only on the last level) and the second strongest is the Horned Reaper. To obtain the Horned Reaper, a Dark Mistress, Bile Demon and Troll must be sacrificed in the Temple Room. If left doing nothing, Horned Reapers will become angry and start attacking the player's other creatures. This can be avoided by ensuring the Horned Reaper is busy at all times. They will only go berserk if left to their own devices. Researching, training, praying in a Temple and patrolling a guard post all keep the Horned Reaper happy. Some players like to create a separate lair, hatchery, treasure room and training room covered by a locked door in order to keep a Reaper for any length of time. They are excellent in battle and immune to lava.
The dungeon has a fleshed-out ecology: some creatures are natural enemies. Flies and Spiders are often found at odds with one another, while a Horned Reaper, if it has gone berserk, will attack all creatures in its path. The Horned Reaper does have one natural enemy though; if a lord of the land is seen by the Horned Reaper, the creature will, without any sort of regard for his allies (or his health for that matter), rush straight at him. At the same time, Warlocks find it incredibly annoying if other races wander through their library, and Warlocks above level 1 respond by attacking intruders. Warlocks particularly dislike Vampires. Skeletons and Bile Demons are also natural enemies, being opposites. Also Samurai (when controlled by the player) can cause fights with a Dark Mistress when resting in the same lair.
The goals for each level are fairly straightforward: they generally fall along the lines of eliminating the heroic force or destroying all other Dungeon Keepers on the level.
The final boss of the game, the Avatar, is the same Avatar from Ultima 8.
Sequels and expansions
The Deeper Dungeons
Dungeon Keeper Gold Edition
Dungeon Keeper Gold Edition was released 31 December 1998, in North America. It was not a sequel but a repackaging. It contained the original game, Deeper Dungeons, 3D patches, a game editor, and a novella. The book recounted the story of a hero killed while exploring the dungeons. Most of the additions were put on Bullfrog's website. The Gold Edition was discontinued but later repackaged and redistributed by EA Digital Illusions CE.
A sequel, Dungeon Keeper 2 was released in June 1999. A third game for the PC was in development but was cancelled. The series made a return in 2013, with a mobile game.

- 2001's Startopia
- 2004's Evil Genius
- 2006's Ghost Master and Dwarf Fortress
- 2007's Overlord and Holy Invasion of Privacy, Badman!

- The 2009 board game Dungeon Lords has been termed "a non-video game spiritual successor" to Dungeon Keeper.
- 2013's Impire has been called "Dungeon Keeper with a side of Dawn of War."
- 2013's War for the Overworld is a project held by its creators Subterranean Games as "a true spiritual successor to Dungeon Keeper", and has been endorsed by Peter Molyneux, creator of the original game.
- 2013's The Mighty Quest for Epic Loot has been called "A weird combination of Diablo and Dungeon Keeper".
