Sonic.EXE

In Sonic.EXE, you start as Tails and move through a level. But things don't look right. All the little animals have been slaughtered. Then you find Sonic. But Sonic doesn't look right, either. He tells you he wants to play but losing this game can be fatal. After Tails, you play as Knuckles the Echidna then as Dr. Robotnic. Sonic gets no nicer, however.
