EA Partners, a division of Electronic Arts has announced an agreement with Valve to distribute Portal 2 to stores nationwide on it's release date of April 21st, 2011.

“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 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.
