Query: Good, But Short

I enjoyed this game immensley for the whole 2 hours or so it took to beat it. It's about an 1/8 of the size of origional HL. The new high definition weapon and model pack that comes with it is great though. It makes the scientists, security guards, and aliens look much more realistic. And it replaces some of the old weapons for instance, the glock for a beretta, and mp-5 grenade + launcher to an m16 + grenade launcher. That little upgrade enhances the game so much that I would buy it just for that. But back to the game, it was fun, with good scrpted scenes and puzzles (i got stumped a few times on em But eventually worked them out.) As I said before, fun while it lasted.
