This may not exactly be co-op news, but Sony's latest ad campaign for the PlayStation 3, called Long Live Play, is certainly worth watching. Not to give too much away, but the idea is how a player impacts the lives of the characters they play in modern day games.
As you can imagine there are plenty of Sony franchise characters on display, including some co-op favorites like Sack Boy, Nathan Drake, and characters from the Resistance franchise. What's more surprising is the amount of 3rd party characters on display in the two minute ad.
