http://www.gamersbook.com/scene/beta/ravaged/ Post apocalyptic FPS, looks a little like rage, to be honost I dont know much about the game but ^^^^^^^ 1500 beta keys if you sign up for a gamersbook account.
says visit steam to activate key. I have searched steam and looked at support. I cant see where to activate the key.
Open Steam, go to Library tab. In bottom left corner click "add a game", then "activate a product on steam"
