Killzone 2 Graphics Only Possible on PS3, says Sony

Since its release, Killzone 2 has garnered critical praise for its intense gameplay, refined multiplayer and detailed graphics; indeed, the game was awarded a nine-out-of-10 by GameDaily. Speaking to GameDaily BIZ, SCEA's VP of Product Marketing Scott Steinberg proudly proclaims that Killzone 2 shows off the true power of the PS3.

"No question about it, Killzone 2 is definitely one of the PS3's top visual showcase games as a single player and multiplayer experience," said Steinberg. "It's not just us; media response to the visuals has been overwhelming, with many outlets claiming that Killzone 2 is the most graphically stunning FPS game to date."

"This type of graphical presentation could only be reached with the advanced game engine and deferred rendering techniques that Guerrilla Games implemented as well as paring that with the horsepower of the PS3's Cell processor," he added.
