Named Game of the Year by over 50 publications, Valve's début title blends action and adventure with award-winning technology to create a frighteningly realistic world where players must think to survive. Also includes an exciting multiplayer mode that allows you to play against friends and enemies around the world.
This is one of the two demos released for Half-Life. The first one, called Day One, was just shipped with certain video cards and never released to the public. It contained the first day of Half-Life's story, from "Black Mesa Inbound" to "We've got Hostiles". Half-Life Uplink was the official demo released in 1999, and it contained a few unique levels that didn't appear in Half-Life. This is the original installer, it may have some problems with newer OSs and it doesn't have some features of the Steam version like 32-bit color mode. This installer doesn't require Half-Life (Original or Steam version).
