Valve will release Portal 2 on April 21st, 2011. Partnering with Electronic Arts to publish the game, in retail channels. Aside from recently being announced as the most anticipated game of 2011 at the Spike VGA’s, Portal 2 already has a huge following and will likely be one of the best games of 2011 if Valve’s track record is to be believed. Which at this point is a near certainty.
Portal 2 will see players introduced to a host of fresh new puzzles, devious new test chambers in never before seen areas of Aperture Science Labs and be reunited with GLaDOS, the occasionally murderous computer companion from the original Portal. The game’s all new co-operative mode will feature its own unique campaign and characters, and will force players to both act and think together. – EA
