When an unstoppable force meets an indestructible object... You are a robot with impenetrable armour, and you wield a gun that fires bullets which cannot be stopped. You fight lesser robots on a looping map – the only danger is yourself as the map becomes ever more filled with your unstoppable shots. Clear each level of its robotic denizens before moving to the next, and eventually face up against the lethal Rogue AI. Source: The Game Website.
