Hopefully it'll be more killzone 2 than 3. 2 had great gun recoil and an awesome last boss fight. KZ3 had a horrible ending sequence (on rail shooter! are you serious?) and a bad ending in general. Online, hopefully it'll be more like KZ2 also, choosing servers, having spawn grenades, no stupid mines that everyone used for easy kills.
Yeah the Radec fight in KZ2 was all sorts of awesome! He was a badass
