If you took part in the promotion to get the game on Steam, you will need to register and contact the Running With Scissors team and request your key. Here are the instructions: http://steamcommunit...50398919161255/
They cross-check your information, so don't bother trying if you didn't contribute to getting the game on Steam. I don't seem to have the game on Desura, so here you go.
I took part in the promotion, registered and PM'ed Toploader on the RWS forums, got a key, and it's already been redeemed. Super cool. Now I have to PM him back and try to get another. Always my luck.
