one stage till death

When twenty strangers wake up in a box, with no memory of the past, they will encounter the man who's voice echoes through the box telling them what they have to do. If you do not complete the stage blood will spill. If you deviate from the rules of the stage blood will spill. The stages will inflict physical pain, but the real challenge is staying sane. (Mature rating due to violence that might make some uncomfortable)
