Haha! Mine finished last night! I dunno what they changed, but it definitely plays like 2k4! I miss playing this game and now I have a legitament install!
Yeah I'm still not sure EXACTLY how they changed the game to make it feel better. There are a few things that I did notice as being different. Run speed seems a bit faster, its not nearly as easy to kill yourself with the rocket launcher or flak cannon, easier to hit people with the shock, stinger has a tighter spread at longer ranges.. and various other minuscule changes that seems to have made a substantial difference overall.
Oh and lets not forget the slew of new graphical options to check on and off. I unchecked the bloom and depth of field option. It feels a whole lot brighter now and closer to 2k4. Plus the bloom was making my eyes bug out.
