Usurper Battle System: Titans of Tartarus

From the triangular game pieces to the diamond shaped game board you'll have trouble finding anything like what the Usurper Battle System has to offer. You'll have an even harder time putting this game down once you've learned the rules.

In this campaign (Titans of Tartarus) You'll choose one of the four banished Olympian Gods. You'll build a team of specialized Mortal units and together you'll use them to unleash a Titan's power and escape the prison you've been banished to.

This campaign comes with the Core Rule Set, a game board (Battleboard), 2 full sets of Battle Tokens including 8 Gods, 12 Mortals and 2 Titans.
