Gamerevolution: Best DLC Add-On 2011
What’s better than wracking your brain to come up with solutions to the most elaborate spatial puzzles ever thought up by the most deranged, egotistical, and homicidal AI this side of HAL 9000? Doing it with a friend, of course! Portal 2 gave us more than just a fantastic new single-player installment, which probably would have been enough to satisfy most fans in its own right. The multi-player portion represents an evolution of the original’s ingenious gameplay, allowing for even more complex puzzles with two players working in tandem.
