Everyone's been waiting for Black Mesa Source since who-knows-when, and it's finally here after years of working on it. I think it's really amazing and FREE so download it here: http://www.blackmesasource.com/download.html Pick the "AtomicGamer" mirror for one single download, the others have two or more, so it's just simpler.
