If you were not aware, aka perhaps you were still hiding under a rock somewhere, Portal 2 launched today. Yes, Portal 2, with both the original single-player mode and the co-op mode where you’re controlling two robots for the greater good of trans-dimensional cruising. There has been just a little bit of excitement leading up to the launch, and all kinds of craziness popping up around the web regarding the game. Legos, aliens, and disappointments. Pity the poor college students who couldn't afford to buy the game. See our favorites after the cut.
