I played the first level like a proper noob, firing all over the place and not using cover effectively - I have beaten this game on Elite, it's been a LONG while since I played any FPS, let alone KZ2 with it's weird delayed movement.
Anyway. Around the point where you have to take out the tanks, I rediscovered the knife. Since then I've been cut-rushing the Helghast just like I always used to, and mowing them down in their masses. It really is more effective than any gun, although it's extremely detrimental to online play and I don't want to get into the habit of being a 'beserker' - does anyone know if the knife has been knerfed in KZ3? --- Why? Because **** you is why.
