The community developed recreation of Valve's original Half-Life.
The sci-fi shooter that put Valve's name of the map is brought up-to-code thanks to fans who have meticulously reworked the original Half-Life to run on modern systems with all the features of Steam. Much of the game's original audio has been remastered as well as all-new additions to expand the cult classic. Currently the single-player campaign is missing the final Xen level to be complete, which is due sometime around summer 2017.
