War for the Overworld

War for the Overworld is an upcoming real-time strategy video game in development by independent game development studio Subterranean Games. Like in Dungeon Keeper, the player (in WFTO named as Underlord) builds rooms, traps and hires creatures as well as trains them to defeat adventuring heroes that enter player's dungeon.

As both of these games share similarities, War for the Overworld is considered a spiritual successor to the Dungeon Keeper series.
