Turtle Rock is now inviting gamers to sign up for the Evolve PC alpha, but you won't be able to participate.

In a decision that we assume has something to do with latency, the alpha is only open to players in mainland North America (Hey, Hawaii: one of us!).

If you do happen to be based in North America and wish to participate, you'll also need a valid Steam account and be prepared to sign a "Game Demo Participation Agreement".

Fill those criteria? Head here and enter the password "happyhunting", you lucky...

If it weren't already obvious, Evolve is very good. The four-versus-one shooter just won the E3 Critics Award 'Best of Show'.
