Counter-Strike: Global Offensive is officially available as of today. But if you haven't touched the beta or purchased the game retail, feel free to get familiar with some of the old-school maps and new(ish) school modes right here.
This video gives you a glimpse at what the first-person shooting action in CS: GO is like, game skills courtesy of our own Chris Person. It's not unlike Valve's immensely popular Source, full of tightly wound maps and Counter-Terrorist versus Terrorist objectives (plant the bomb, defuse the bomb, save the hostages, kill your opponents as much as you can).
The video features a glance at the Bank and Dust maps. We'll have more on the new Arms Race mode, modelled after the Gun Game mod for Counter-Strike: Source that rewards kills with a new weapon later.
Oh, and, for Chris's sake: keep in mind this was his first time playing GO. And it's been years since either of us played Source.
