You are Killer Bean, a rogue assassin who takes out the trash in this world, one bullet at a time. The procedurally generated story changes every time you start a new campaign in this third person, roguelike shooter.

After being betrayed by the Shadow Agency and learning the truth about their evil ways, Killer Bean has made it his life goal to destroy them. Yet this is easier said than done, as Killer Bean will face armies of enemies, and mysterious Shadow Beans who are better trained and more powerful than him.
