The Half-Life 25th anniversary has brought us a deluge of new material. We've seen cut characters restored, additional maps for Half-Life Deathmatch, and a full-length documentary about Valve and the creation of the epochal FPS game.

Half-Life 3 might never happen, but after a quarter of a century, the original game is still getting love from its creators.
