In an attempt to cease the insane flooding of fanboys to all the major Half-Life 2 sites and causing several web servers to burst into flames, Doug Lombardi has issued a press release.
If you have purchased a copy of Half-Life 2, we are sorry you are still waiting to play. This is not Valve's choice. Vivendi is insisting that the game has not yet been released, and has threatened that Valve would be in violation of its contract if we activate the Half-Life 2 Steam authentication servers at this time.
Thanks for your patience and we will update you when we have more news to share.
There you go folks youre all waiting until the 16th. Its not too long to wait now is it? Now dont go out and start rallying outside Vivendis offices with pitch forks. The game was never meant to be available until the release date so go blame the retailers for breaking the agreement.
