Point Apocalypse

He enters a prison world. A place of no return harboring the death of the universe. No proper food or drinking water, no modern technologies. He doesn't know who he is. He can't tell friend from foe. He has no idea what brought him here. He has no time to think. He lives from one objective to the next. The Earth's laws end here. No one to turn to for help. The lives of thousands of people now depend on him alone.
