At CES, I played Killzone 3 with Sony’s PlayStation Move gun attachment. After you plug in a PlayStation Move and a Navigation controller, the Sharp Shooter remaps buttons so you can fire bullets by pressing the trigger. The controls sounded simple enough – move the gun to look or aim, analog stick moves your character, and L2 to zoom in.
Partially due to sensitivity, there is a bit of an adjustment period since you have to gently move the gun to target the approaching Helghast army. Targeting snipers was easier. After zooming in with L2, you can fire blindly with your character’s machine gun. When you’re out of bullets you can reload by hitting the bottom of the gun (as if you were loading a clip in) or tilting the controller. A Sony representative suggested titling was the easiest way to reload. I’m inclined to agree.
What’s interesting about Killzone 3’s Sharp Shooter controls is the game doesn’t use all of the features on the gun. There’s a pump action (think shotgun) trigger, which a rep said developers could use for secondary fire. The Sharp Shooter also has three fire settings: single shot, burst, and automatic. Killzone 3 doesn’t utilize this feature, so the switch isn’t mechanical and a player using the Sharp Shooter won’t have an advantage online.
Right now Kilzone 3 is the only game that supports the Sharp Shooter, but a Sony rep said there will "likely" be more PlayStation 3 games compatible with the accessory.
