Released in 2012, Black Mesa is a fan-made recreation of Valve Corporation's 1998 debut Half-Life.

Developed in an updated Source Engine, Black Mesa features enhanced graphics, physics simulation and level design - notably including the omission of several of the original game's notoriously frustrating first-person platformingsequences.

The recreation also includes new original voice work which strongly echoes the original cast, and a full original score composed by Joel Nielson.

Famous among gamers for its lengthy, extended development period, the title was widely regarded as vaporware until the developers decided to release its first installment, containing the chapters of the game up to and including "Lambda Core".

The recreation was eventually added to the Steam Greenlight program where it was approved for distribution on the popular digital download service. As of 5th May 2015 the game is available for purchase through Steam's Early Access programme. This new version of the remake features further graphical improvements, including the replacement of some Source engine assets with unique models and a further improved lighting system. However, the developers are still completing the game, and while the rudimentary multiplayer component of the title is now available, further development is planned, along with the addition of the Xen chapters of the game.
