The first rule of Supremacy is: There are NO rules

Supremacy MMA brings the brutality of unsanctioned, amateur and unlicensed MMA fighting to your 360, favouring fast-and-furious gameplay and underground aesthetics over official branding and television-style.
The game aims to raise the bar in the MMA space by bringing an unprecedented level of fast, fluid combat, intuitive controls and true-to-the-sport brutality. It follows the rise of fighters and their individual stories as they fight their way to Supremacy.
