This will get you into the alpha/beta, as well as the final game. Thanks to Valve’s generousity, this version will also get you a Steam key in addition to the stand alone key. The stand alone version currently does not have a working multiplayer, only the Steam version does. We will send you a link to the Steam key claim page along with the stand alone key once the preorder payment goes through. Sometimes the email might end up in spam, so please check there as well. If you’re having trouble receiving the key(s) in your email, please use this link here to resend.
