Section 8 Euro Beta Sign Up
Right, it looks like I was a bit confused on this front: the next stage of Section 8's testing is a European beta, since the first lot was North American, and it does have limited places. You can sign up here. That European beta will start on the 10th. For my recent impressions take a look here. Kristan at Eurogamer was also pretty positive. As I understand it, an open beta, presumably for both continents, is to follow. The game is scheduled for release worldwide on August 28th.
