In 2007 Gabe Newell, co-founder and managing director of Valve Software, described the PlayStation 3 as “a total disaster on so many levels”. Four years later, he seems to have changed his mind. Not only is Portal 2 an absolutely incredible game, the definitive console version is most definitely only available on PlayStation 3, featuring Steam integration and a free copy of the PC version! Chell and GLaDOS are back for yet another brain-teasing portal-based adventure, battling deep within the depths of the decaying Aperture Science facility. Plus, players can now team up with a friend via split-screen or online to take on an entirely separate two-player co-operative campaign!
