The original release date for the project was set for 2009, but was delayed for 3 years. Originally requiring Source SDK 2007, Black Mesa is now considered standalone and now available at Steam. The ultimate goal of the mod is to recreate the original Half-Life from the ground up, using the advanced capabilities of the Source engine to create a new and more engrossing in-game world with more varied, complex environments and more challenging, realistic gameplay. Black Mesa, previously known as Black Mesa: Source, is a fan-made remake of the original Half-Life.
