War for the Overworld is a real time strategy "God game" that includes FPS and RPG elements. The game is set in a medieval fantasy world where the forces of good oppose the evil underground keepers.

In War for the Overworld you have the power to create vast dungeons filled with hordes of evil minions who share a common goal: to crush the bones of the goodly heroes that dare to enter your unhallowed halls. You will command mighty armies, create vicious traps and cast dastardly spells to overcome the pitifully gallant armies that defend foolish principles such as "honour" and "righteousness" - it's going to be more fun than taking candy from a baby..

War for the Overworld is currently in development by Subterranean Games, who have many past and present Nexus mod authors among their ranks. Considering their modding background they have every intention of making War for the Overworld an extremely mod friendly game.
