It's hard to believe that Half-Life was ever an unreleased and anticipated game. Still, I'm surprised how different this trailer -- packaged with You Don't Know Jack Vol. 3 in 1997 -- looks from the final game, which Valve released in 1998. That must have been one busy year for Valve.
I like how the guns just sort of float in midair, with no hands holding them. Valve was also smart enough to start with an explosion.
