The Portal 2 Blog announces the winners of the Portal 2 summer mapping initiative. They spent 140 man-hours playing through 280 entries to select the three best user-created maps for the puzzle/platformer sequel: "Patent Pending was the overall winner with Infinifling grabbing second place. The voting was so close, we added an honorable mention for Edifice." They offer instructions on how to play these maps, and outline the prizes the winners are getting, also taking the opportunity to re-pimp their Portal 2 music video contest.
