As of now, this is possibly the most realistic 3D shooter I've ever played.  No kids allowed here!  (There's a Wal-mart (censored) version, but it's not as fun)  The graphics are excellent, and everything could have  happened.  Your objective is to destroy 4 nukes that were stolen.  No  aliens, zombies, plasma guns, or super death rays are in here!  The weapons  are even modeled after real-life ones, for crying out loud!  Of course, the  funniest thing is the "gore-zones."  Depending on where you shoot  a guy, a gun shot or a knife mark will appear there.  Blowing off half of a  guy's head with a shotgun can be the UNTIMATE stress reliever.  Sure, it's  more violent that even Kingpin, but in SoF, an F-word isn't inserted  casually into every conversation.  However, SoF is not perfect.  The AI can  be quite stupid at times, with people running in circles, or ignoring you  entirely.  Plus, in the later winter stages, there is a fog which can get  really annoying when the AI can see you, but you can't see them.  Other  than those problems, I think SoF is an otherwise flawless game.
