That page has all the info on the update, which has been in the planning for almost 3 years now! And a co-op gametype will be very interesting to see, there's been a pretty basic bot AI in the game for a while now, so it'll be interesting to see if it is up to the task. Then again, Valve wouldn't be releasing it if they weren't happy. Even though the ARG that was supposed to be leading up to this should have taken weeks to figure out, and not the ~12 hours that it was actually solved in.
ROS has a pretty good summary of what had happened up to this point.
So, anyone looking forward to this? I still love that despite how old the game is, it is massively popular and still gets massive updates, and its free as well.
