Dungeon Keeper was developed by
Bullfrog Productions under
Peter Molyneux, who wrote the game design, testbed, and the computer players and assistant. Programmers Simon and Dene Carter also said
Dungeon Keeper is a parody. Development began in November 1994 by the lead programmer, Simon Carter, and took two and a half years to develop. The navigation system proved difficult to develop because computers of the time lacked power. Artificial intelligence was considered crucial, as the navigation and other aspects relied on it. According to co-designer Jonty Barnes, the team wanted the creatures complex without high computational costs. Healey came up with the idea of slapping creatures to make them work faster, and Barnes considered it a "great game decision".
Dungeon Keeper uses lighting
algorithms used in
Magic Carpet, which provided effects such as fireballs lighting corridors. According to Molyneux, in May 1995 publisher
Electronic Arts told him he had to ship
Dungeon Keeper in six and a half weeks. Though he satisfied their demands by producing another game,
Hi-Octane, in the required time frame, his relationship with the publisher was strained. Development on the level editor began in May 1995. The first-person view was developed in September 1995, and the creatures had shadows added, which was believed impossible at the time. He explained that it was mostly complete, but wanted to make sure that it was "absolutely brilliant". In February 1996, Molyneux decided to focus on the project full-time. In July 1996, Alex Peters joined the project and ported the game to Windows 95.
Dungeon Keeper was shown at the
European Computer Trade Show in September 1996,
Sega Saturn and
Sony PlayStation versions were in development and due for release in 1997, but cancelled. An internet version was in development, and would have supported up to 250 players. Carter wrote and organised 800,000 lines of code. The music was composed by
Russell Shaw and, according to Healey, this came late in development. Healey produced 90 per cent of the graphics. Most of the creatures were the team members' ideas, although Molyneux was involved with the Imps. who ultimately become the game's mascot. Before the redesign, instead of having Imps dig the gold and minions entering through portals, the game had the player dig gold and use it and
mana to create minions. Molyneux also liked the fact that the game adapts to the player, enabling the choice of the preferred methods and strategies, He stated that he was proud of
Dungeon Keepers concept, but remarked that doing original things takes time. He also liked that people were unable to describe
Dungeon Keeper in any particular way. Molyneux also disliked the lack of opponent personality, and some features being hidden too well, including (according to him) a cheat code that made the mistress creature naked.
Dungeon Keeper was Molyneux's final project with Bullfrog before he left in July 1997 to form
Lionhead Studios, and after completion, he stated that he wanted to make "
the coolest game ever". and his departure was one reason he wanted to make the game good. A sequel,
Dungeon Keeper 2 was released in 1999, and the series was rebooted by
Mythic Entertainment with the release of a remake (also titled
Dungeon Keeper) for
iOS and
Android on 30 January 2014.
SoundFont support The game uses SoundFonts to provide additional ambient sound effects. A
Sound Blaster AWE32 or
AWE64 is required to use this feature. The player can load a SoundFont and use it for ambient sound effects. Customised SoundFonts can be created to personalise the dungeon. The game features three SoundFonts, one of which is loaded at game startup,
Expansions An
expansion pack,
The Deeper Dungeons, was released on 26 November 1997. It features fifteen new levels each for single player and multiplayer, and an improved
artificial intelligence for the enemies. The Avatar also reappears in the final level.
Re-releases The game was re-released in 1998 as
Dungeon Keeper Gold Edition, which included the
Deeper Dungeons expansion as well as a
Dungeon Keeper-based
desktop theme. In Japan, a similar edition was released as
Dungeon Keeper Premium, under the EA Best Selection brand. This version included the content from the
Gold release, as well as both Japanese and English text and audio options. GOG.com launched a
macOS version in October 2012. The game was available there free of charge for a few days in February 2014. In October 2016,
Dungeon Keeper was released free of charge on
Origin, via its "On The House" programme. ==Reception==
