1 or 2 player co-op survival game. You were out on a mission to find a new base for you and the other survivors to call home for a little while. Upon your arrival you were ambushed by a hoard and lost all your supplies. You must now use whatever you can find to clear your way through each section of the Prison before it is safe for your company to set up camp. Look for instructions along the way and locate the Bomb to set off in the Watch Tower to complete the game successfully.
