Portal 2 official release date announced, April 21, 2011

Recently named the most anticipated game of 2011 at the Spike TV Video Game Awards, and releasing worldwide in April 21, 2011, Portal 2 will see players introduced to a host of fresh 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.

“Portal 2 is Valve's most innovative title in the company's history and will be launched with a first-class launch campaign this April," said Doug Lombardi, vice president of marketing at Valve. "We're excited to be working with Electronic Arts to deliver this title as we expand our platform strategy to include the Mac and PlayStation 3 platforms.”

Portal 2 will be available for the PlayStation3, Xbox 360, PC and Mac on April 21, 2011.
