In this video Guerrilla Games' Steven Ter Heide walks us through what it's like to play Killzone 3 with the PS3's Move controller.

He also talks us through some of the design decisions for the motion-control option. Of course, if you'd rather play through the game using your Dualshock, that's supported too.

What Guerrilla Games hasn't decided yet is whether while playing online players using Move will be able to take on players using the Dualshock. They need to make sure there's no unfair advantage either way, they say.
