be careful with which game you download, if you copy it from a friend then you must install punkbuster (punkbuster.com installer, no need to reinstall) but if you download Skulluptura RIP from internet then it has no good multiplayer...i downloaded it an believe me, it doesnt work....if you wanna download look for Razor or Procyon rip they work
be sure to contact me to give you fast, no wait links...anyway...
Hawk (and other cracked owner's): if you want a cracked list i suggest download KQuery..
here's a great list plus instructions on KQuery (which i recmmend)
