Still thinking a lot about how much Black Mesa's Xen feels like a complete disgusting counter to everything it's supposed to represent. How it feels much more like a portfolio-driven set of levels in terms of design rather than anything cohesive. How, despite being on a completely alien majestic world, the way you actually interact with said world is obscenely familiar, trivial. You do the same sort of puzzles you did in stuff like Office Complex or earlier. Even in space, you cannot escape 30+ minutes of connect power cord, walk to area, shoot 2-3 enemies, connect power cord. Xen is not Alien. It isn't an apotheosis either. You are empowered to enact a simulacra of other games instead, like later half-life games with the elevator and chase sequence. I do not hold Xen in HL1 in the highest regard possible (nor do I for HL1 much in general anymore, honestly :/), but it was at its core a fervent 'betrayal' of the familiar. It's reviled for this decision but it is altogether fitting, how platforming is a disgusting poor feeling challenge because, well, this planet was not built for the likes of you. You're simply fighting through a world that was never expecting you to be here. But in Black Mesa it doesn't even bother to truly be dangerous. Granted, that's true of Black Mesa in general the more I mull over it. There's a lot to dissect on how Marines function both as an aesthetic issue and a mechanical one here vs all of the other HL's enemies. In a way, Black Mesa is a betrayal in of itself to me because it seeks not to conserve any spirit of what it's remaking as much as it pushes it through a meat grinder (albeit, with soft hands working the parts, I won't say crowbar's effort was exactly soulless) of HL2 and later design. And to that it breaks down most of those foundations until you have something almost unrecognizable for those who played HL1 and Opposing Force in terms of feel and play and understanding. The aesthetic, on a technical and story lens, is conserved to some degree, in grander majesty. But at what cost?
