We're back again to make you feel old with another anniversary, as Valve's outstanding puzzle sequel Portal 2 officially celebrated its 10th anniversary over the weekend, first releasing back on April 18, 2011.
The game came out for PC, Xbox 360 and PlayStation 3 at launch. and quickly went on to receive glowing reviews from critics and the public alike, becoming one of the highest rated Metacritic titles of all time in the process.
If you've somehow never had the chance to check out Portal 2 over the past ten years, don't forget that Portal 2 is available with Xbox backwards compatibility on modern systems, with the original also available via The Orange Box.
"The highly anticipated sequel to 2007's Game of the Year, Portal 2 is a hilariously mind-bending adventure that challenges you to use wits over weaponry in a funhouse of diabolical science. Using a highly experimental portal device, you’ll once again face off against a lethally inventive, power-mad A.I. named GLaDOS. Break the laws of spatial physics in ways you never thought possible, with a wider variety of portal puzzles and an expansive story that spans a single player and co-op game mode."
