A sudden day Bill awakes cloistered inside a strange fortified building… He is told by voices on the walls that he`s hired to play a game. If he succeeds, he is free; if they succeed, he dies. Apparently he has no choice but to accept to play the game and so he does. At first all he has to do is to leave the skinner-box made to test his skills. Pick some objects, drop them on a processing machine, grab the battery generated by the components and put that battery over a energy slot to open the door. All that just to go to the next skinner-box chamber. Ok for a while, but when chamber after chamber each challenge becomes harder and military threatenings shows up everywhere… Bill understands he may never leave that place alive…
