On the 17th of November, Valve Software celebrated the 10th anniversary of the game that pretty-much made the company what it is, Half Life. Valve used the simple 3D first-person shooter genre, focused heavily on the gameplay elements to churn out an awesome game of its time. With the introduction of the Source game engine, Valve made additions to the franchise with Half Life 2 (HL2), HL2: Episode 1 and HL2: Episode 2. While the company itself could be working on another addition, an independent community-driven group sought to commemorate the 10th anniversary, by remaking the original Half Life using the Source engine. This is not to be confused with the simple Source-engine port Valve created in the form of Half Life: Source. The game is to be called Black Mesa: Source, which is comes in the form of a Half Life 2 modification. The levels, characters, graphics and physics get a refresh to the latest Source has to offer. The game is set for release in 2009. The Black Mesa: Source team has released its official trailer that has been posted on YouTube here. To know more about Black Mesa: Source, visit its home page.
