It follows Sam "Serious" Stone travelling to the future in search of his nemesis, Mental, teaming up with mercenaries on the way. The player controls Sam and his accomplices through confined levels, engaging in battles through random encounters. These pit the player characters against large waves of enemies, and the player controls the weapons and items each character uses against them in five-second turns.
