As for 3D itself, Hulst is adamant that it is an option, not a requirement, for Killzone 3. "3D is a great feature, but it's an option to the game. I don't want people who don't have 3D to have a suboptimal experience," said Hulst. "But we don't want to alienate the core audience. The same with Move. These things are options. They're great options. I think they're here to stay."
Unfortunately, the game will not boost itself up to 60 frames-per-second when running in 2D and is locked to 30 FPS regardless of what dimension you're playing the game in.
Killzone 3 will be released for the PlayStation 3 on February 22, 2011.
