Guerrilla Games boss Hermen Hulst believes Killzone 3 pushes the PlayStation 3 hardware to capacity.
"We're pushing 100 per cent right now," Hulst told VG247. "You see, there's steam coming out of the machine, almost. All the stuff that we're squeezing, it's got everything to do with the scale and the environments and the action that you're seeing on the screen right now.
"As I was talking about earlier in the presentation, we're having a footprint of a level that's ten times bigger than the average Killzone 2 level. Killzone 2 was not a small game, but that was as far as we could push it back then.
"We're going way overboard this time around," he added, "and I think we're reaching the kind of maximum that we can do. But we always do that. We always find a way to go above and beyond."
Guerrilla Games will benefit from PS3 developer tools used by other first-party Sony studios Sony Santa Monica (God of War III) and Naughty Dog (Uncharted 2).
Killzone 3 will be released sometime next year and was unveiled to the world yesterday. Read Eurogamer's preview to find out more.
