The Black Mesa mod is a remarkable accomplishment, remaking Half-Life in the Source engine, and now a mapper building upon their work has remade another slice of Valve history. Black Mesa: Uplink remakes HL's classic Uplink demo, which curiously for a demo was a new slice based upon levels cut from the game during development. And now that's available in shiny Source-o-vision.

Black Mesa: Uplink is out now on its ModDB page and here on Shacknews. To play, you'll need to own a modern Source game on Steam and have the Black Mesa mod installed. Mapper Michael 'Hezus' Jansen made Uplink over three months, building upon the assets and eight years of work from Black Mesa.

Set roughly around Half-Life's Lambda Core chapter, Uplink sees Gordon Freeman on a mission to activate a radio antenna so people can escape, only an awful lot of soldiers, mutants, aliens, radiation leaks and jumping puzzles are in his way.

"I've recreated something people played 13 years ago, that means it's intertwined with nostalgic feelings," Jansen said in the release announcement.
