There’s a rumor on the net that Valve is giving out keys to some unknown game. We just wanted to clear it all out, you just have to go here (http://myzerogear.com/beta/invite.php) and get your free beta key for Zero Gear – a funny racing game (similar to Mario Kart). So don’t listen to some morons on the Internet and don’t think of buying this key either when someone wants to sell them – those keys are totally free and temporary.

After you receive a key enter it in the Steam client and download the free beta while you can! The game takes around 240MB.
Have fun!
