The Skirmish screen
Skirmish is a game mode in Dungeon Keeper 2 in which the player goes up against computer-controlled enemy Keepers.
Many things about the game can be customised, including toggling Fog of War, availability of rooms, traps, doors, and spells, game duration, what happens when a Dungeon Heart is destroyed, the Creature Pool and maximum number of creatures, game speed, mana regeneration rate, and gold density.[1] Also customisable is the intelligence of the enemy Keepers.
Dungeon Keeper also has a Skirmish mode, enabling players to play multiplayer levels in single player mode, although it's hidden. It also doesn't allow the customisation of game rules. It is accessed by using the -1player parameter when launching the game.[2]
