Last night, Sony threw a mini-bash in downtown San Francisco to celebrate the PlayStation 3 turning two. Killzone 2 played on one TV, Flower on another, and Resistance: Retribution was on a third. At first glance, the PSP station looked like folks were playing the same level the world was introduced to at E3, but upon closer inspection, it became clear that this was Resistance: Retribution running with Resistance 2 and PSP Plus functionality.
