At the first event for Killzone 3 in the US Hermen Hulst wanted to make it clear that Naughty Dog have nothing to do with the graphics development in Killzone 3. Recently there were rumors circulating that Naughty Dog would be helping with the development of Killzone 3, which lead to speculation that they were working on the snow environments.
Although Hermen shot down rumors of Naughty Dog working on the graphics, he did not deny that Naughty Dog is indeed lending a helping hand. Like A.B Frasier said on this week’s episode of The Co-op Podcast, outsourcing to other developers is common in the industry.
