Kingdom Under Fire: Circle of Doom is the fourth video game in the Kingdom Under Fire series and it continues the story from Kingdom Under Fire: The Crusaders. Unlike all previous games in the series this title does not feature any strategic games elements. Instead it is entirely presented as a Diablo-style single-character hack-and-slash RPG.
The game features a random map generator and semi-destructible environments. Players can damage most things but not to destroy them completely. There are six playable heroes to choose from. Some were already featured in previous games while other are entirely new. Each character has different story quests, but identical level sequences and bosses.
