It's somewhat disappointing that the demos will be games that will have been on the shelves for weeks; in Killzone 3's case, months. Some had hoped the disc would have demos for Uncharted 3: Drake's Deception or Twisted Metal.
Resistance 3 is the third game in the shooter series, the first of which, Fall of Man, was a launch title for Sony's console. The game will be released September 6 in NA, September 9 in EU.
