Great game, was originally a student project at DigiPen Institute of Technology called "Nitronic Rush" - they visited my middle school when I was a kid, nice to see the full game come to fruition - and it's workshop support for tracks, this game is great!
Black Mesa is a work of art, and it's because of this game that Half Life 1 is able to live on with future generations, yes the original is great but this is PERFECTION.
