The public beta of Counter-Strike: Global Offensive has been delayed after professional players of Counter-Strike 1.6 provided feedback to developer Valve.

The professional players were asked to play the game first, as they are able to give constructive feedback, something that can be hard to come by from regular gamers, estimates Valve's Chet Faliszek.

“They gave us a lot of feedback on things we should get in the game before we release it, otherwise we're going to be getting a lot of bug reports or a lot of feedback and it would just be redundant.”

There's going to be things we're going to release it with knowing we need to add more, to do more,” he continued. “But just knowing there's some feel and some just operating the game issues that need to be resolved first. We want to get those done first.”

The Counter-Strike: GO beta was originally scheduled for October. When it does open, it will include only one or two maps. As to when it ends, Faliszek says, “When it’s ready.”

“We have no mandate from anybody of when we have to ship this. So we're more than happy to just keep working on this 'til it's ready to ship.

“By the end of this, everyone will be playing the game – it will be the released game that you're just playing. Then, at some point, we'll say, “’OK we're going to release it.’”

Counter-Strike: GO was originally estimated for release in early 2012 on PC, PlayStation 3 and Xbox 360.
