Counter-Strike: Global Offensive is launching on PC in a few hours after an extensive beta period.
Just in time for that, a patch hit yesterday for the game which added a training mode ("Weapons Course"), and also some love for Zombie Mod. For CS newbies like myself (I know, shameful), the mode should ease the learning curve some, while Zombie Mod will alleviate your primal zombie crushing urges.
The patch also tweaked the UI and fixed yet more bugs, so there's further polish to look forward to, as well.
Hit the source if you want the full notes.
