I know a lot of you have been waiting for this one, at least I was, now going through the game in 'Realistic' mode, this great game sure has kept me entertained for the last month or so.
The long awaited 1.2 release adds quicksave support, increases run speeds and sprint lengths, fixes some Punkbuster problems, addresses a large number of gameplay issues, applies various optimizations and weapon tweaks, and squashes more bugs.
UPDATE By Per: We have received an alarming number of complaints from ATi card owners that are experiencing crashes after installing the 1.2 patch. The issue is being looked. At this time we suggest re-installing your game without the 1.2 patch.
