Subject 15 wakes up in a science lab after getting hit by a car. A scientist comes in and informs him that nothing that he knows is real. His world was just one of many false universes created to test out. In the real world, there is never ending war, and the scientists hope that by creating many universes with different circumstances, they can turn their world into a utopia. Subject 15's only options after exiting the test are to work with the scientists, or to have his memory wiped and to try out a new world.
