Today, the Black Mesa Team released an impressive trailer for their remake of Half-Life . The remake is a total-conversion mod for Half-Life 2, bringing the updated graphics and AI of the Source engine to the original game. The team has been dropping hints lately that the project, which began in 2004, is almost done, and the trailer confirms that it will be out in 2009. They also recently announced that they've "dropped Counter-Strike: Source as a requirement for Black Mesa, and from now on, the only thing you'll need to play the mod is a Steam account with any Source engine game installed! Black Mesa is now running completely off of our own content and base Source shared content, and we felt the vastly increased user base more then [sic] justified creating all the extra assets needed to make this switch."
