Wow, getting the last key was a downright pain. I felt I would never do it! but ty for the game, and thanks for including an option to turn the music off!
Lol how could anyone find this hard? :/ Search for weapons untill you get the magnum... Then use that as your main untill you get the sniper rifle.. After that forget new weapons concentrate on finding survivors.. After you have seven only send your time rebuilding your base and instawin.
