Dungeon Keeper is a real-time strategy game with an isometric view in the medieval genre. The game has several modes. In addition to training and multiplayer play, as in any strategy, there is a story campaign, which consists of suppressing the opposition of good heroes and other Guardians to the aggressive ambitions of the player, whose task is to achieve the cherished goal of every Evil Overlord: to capture and enslave everything around him.
The campaign is divided into missions, the transition between which is carried out using the world map. Unpassed areas are displayed as blooming green areas (when focusing on an area, you can hear the singing of birds), while the captured ones are drenched in blood and engulfed in fires (you can hear the howling of dogs and bells), in addition, the adviser (voice-over) sarcastically comments on the well-being of the unconquered areas, and then The passage of the mission triumphantly describes the devastation and devastation of the area.
In some areas, it is possible to complete additional (secret) missions, usually of a comic nature.
