I bought this game because of the sharpshooter controller (which I HAD to have). I agree with the review above pertaining the the single player campaign. The campaign just isn't very fun. I always buy games because of the single player element, and sometimes play online. On Killzone 3, I have stopped playing single player and moved to multiplayer (which is great). The only part I disagree with is the move control useability. I am playing with the sharpshooter and it is great. It's not accurate enough to have a controller with a site, but it is still a lot of fun.
