That's right, the delayed closed-beta test of Counter-Strike: Global Offensive is now live. Valve, on the official Counter-Strike website, are billing it as a stress test that, "contains a limited set of weapons, items, game modes, and functionality" on "our servers and a variety of client hardware."
Of course, this shouldn't stop you enjoying the game, but bear in mind that if you got into the closed beta, you really should remember to report any bugs or glitches to Valve so they can sort them out as soon as possible.
So, how do you get into the closed beta? Well, if you went to any of the major game entertainment expos this year (like Eurogamer, where halflife2.net made an appearance and interviewed Chet about the GO beta), you will have gotten a key that you can redeem in Steam to add the beta to your account. If you couldn't make it to the expos, don't fret as we've got some awesome new content about the beta coming up with first impressions, followed by extensive testing of the beta, so you know what to expect when the game is fully released, whether you're a 1.6 veteran, a hardcore sourcer, or entirely new to the series.
This will be a long-running series, delving into the depths of the game, and charting how Valve are striving to improve the series, and where they'll be going in future. There's lots more to come, but in the mean-time, get downloading and enjoy the beta!
