Work together to fight your way to the depths of a mystical well known as “Callous’ Lab.” Callous, an indestructible being suddenly facing his own mortality, has been luring unwilling subjects into his well to test his experimental cures. You’ll have to survive his labyrinth of illusions and mind games to reach his final gauntlet. Will you defeat Callous and send him back to the darkness he came from? Or will you fail and become a rat in his twisted maze forever?
