Yes, submissions for this year's Eurogamer Expo Indie Arcade are open, and the final batch will be judged by the Hivemind of Rock, Paper, Shotgun. It's true! This year's event, as last year, will be officiated by the men of this website, which will result in LIFE CHANGING PRIZES (tbc) for the winners. The details are here, but basically you need to get in touch with David Hayward with the details if your game before the 19th of August, and it would need to be in some kind of playable state for the event on 22nd of September. So if you are making in indie game and want awesome coverage, applying is a good idea. A very good idea. A mandatory idea.
Speaking of Expo stuff: the early entry tickets are now all gone, but there are some day tickets still available for the event, which will feature games, Games, GAMES! And we'll be there doing hi-fiving and PC stuff. So you should come along.
