Westurn is an RPG in a post-apocalyptic, action-packed world. The survivors have established themselves in the desert, far from any form of civilization. The government is made up of ruthless gangs that control the cities and the streets. In this world, the law is an abstract concept, and the police are the worst kind of lawbreaker. The only thing that unites the gangs is their common goal: to survive.

The main character is the sheriff of the town. He has a small gang of deputies that are at his disposal. His mission is to capture criminals, collect bounties, and earn the respect of the citizens.

Westurn is a block-based game, with a great emphasis on tactical combat.
