So a few days ago Valve released proof that Counter Strike: Global Offensive is in development. Apparently they had been showcasing (read: testing) their new game to some of the professional players on the CS tour. For once, NDA's actually worked, because honestly, I hadn't heard jack about it til Friday. Sure, maybe a whisper of a sequel, but nothing substantial.
However, if you're looking for a pure sequel, this is definitely not it. Testers have said that it wasn't like 1.6, nor was it like CS:S, but still very good. And some little quirks here and there were added, one in particular, every player starts with a kevlar vest. To most, it won't be a bother, but it does shake things up a bit, since kevlar was traditionally purchased, and not just given.
