Finally "finished" it. Actually, I don't mind that Xen is missing. Xen is horrible, and Questionable Ethics had that little habitat thing, so we know what it looks like
Black Mesa is an awesome thing to behold. I was surprised to see all those little (and sometimes not so little) expansions to the areas. The BM team, fittingly, made a great Black Mesa Research Facility
But what the hell did they do with the soldiers? I don't know if it's their aim, their fire rate, their health or what, but they make this game brutal. I finished HL:S last year or so (it's on youtube!) and didn't have nearly as many problems dealing with the enemies. In fact, for shits and giggles, I whacked the Black Ops gals in the face with the crowbar! [http://www.youtube.com/watch?v=iMqD3BZhKSA]
I tried replicating that in BM. All I got was 7 quick deaths.
Know that part where you shoot down the VTOL(?) with the Grunts around? Fun in HL:S, pure rape in BM. In HL:S you come out some corridor, in BM you drop down a hole and are stuck in a dead end with virtually no cover - and that's before you even get to the damn plane! I'll admit, I just cheated at that point. That was ridiculous.
