You are a team of federal marshals, who find themselves on the "Shutter Island". A mental hospital for psycho killers is located here. Everything wouldn't be so bad, only if not the unstoppable rain and the electricity shutdown. Not more than 90 minutes is left until you run out of the backup power, and the only thing separating psychos from you is electricity. You have to restore the beacon electricity supply and get out. but the only way to get out is through the dock. Good luck!
