Ark is the leading protagonist who begins the game with a case of amnesia. Plagued by a severe headache and nausea, he realised his memory was gone after helicopter crash shown in the introductory sequence. For Ark, the past is shut tightly in the darkness. Thinking about it is like grabbing at fog. It dissipates and is simply...gone. Left alone on a run-down street, the smell of death on the wind, he hopes for someone to come by. There is somebody nearby, but is it friend or foe? His only safeguard is a gun. And it seems that the gun is guiding him. But will it be enough to save him?
