This trailer, created as a teaser for the Dreamcast port of HL1, which would have featured Blue Shift as a small side mission, is very interesting.
Note the lack of any HD (or Medium Definition, as the Dreamcast models are called) models, the yellow HUD, the flashlight weapon, and most of the footage is taken from HL1 maps. Weird. Still, the later Blue Shift trailer is directly based off it. Check it out after the jump.
