The guy who made this knows what makes Half-Life good. Claustrophobic level design, vent crawling and puzzles. He managed to keep the level design fresh even after all we've seen in the expansions and other mods. The ending was something I think we expected but the journey is what counts. I would love to see more from this guy, even if its not for HL.
