played through the black mesa blue shift mod, up through the xen chapter since that's all they've released so far. the mod aims to remake the entirety of blue shift in the style of black mesa, and boy howdy does it deliver on that, for better and for worse.
they actually establish a couple supporting characters, more security guards and scientists, which is nice. in the original game it was basically just dr rosenberg, so more named characters is a good change imo. feels like you're actually rallying people together to fight your way out of black mesa.
a weird thing this mod does is take away player control sometimes. i can understand it for specific sequences, like when the elevator crashes at the beginning or when you first teleport into xen, but it also does it for some mundane things too, like inserting a keycard into a switch. why? half-life's whole thing is letting the player be in control the whole time.
the first few chapters are well paced, but it starts feeling like its padding a bit when you go off to find dr rosenberg. you have to do this whole song and dance moving a train back and forth and turning it around properly on turntables to bust him out. they could have cut out some of the tedium there a little.
my problems really start when it comes to the xen chapter. the original blue shift xen chapter lasts for roughly 30-40 minutes for a first time player, though someone like me was able to speed through it in under 15. with the black mesa mod, they have stretched out the runtime of this chapter to 3 hours.
it starts off pretty strong, you're making your way through xen, taking in the sights and finding all the stuff the previous science teams have left behind. about 90 minutes in i was wondering when i'm gonna get to the focal point relay thing, the whole reason calhoun goes to xen in the first place.
but instead you keep detouring through black mesa outposts and alien factory things and it just gets so long in the tooth. it'd be one thing if you get to one of these places and you're there for 5-10 minutes at most, but you typically spend over 20, sometimes even 30 minutes at these places.
there's one bit where you inexplicably decide to jump on the back of one of the giant flying manta rays and it flies around for like 15 minutes like an autoscroller section until it gets shot down by alien railguns, and then you spend 30 minutes making your way over to and destroying the railguns. and the whole time i'm just like... when are we getting to the focal point thing.
so finally you get to the focal point relay and turn it on but it gets jammed by a signal so you spend another 40 minutes blazing through ANOTHER alien factory so you can blow it up and you make your way back to the focal point thing and the portal's open but alien controllers keep telekinetically grabbing you and yanking you away from it... and it's just so exhausting. i got burned out.
not to mention the weirdness with how they handle vortigaunts. so in black mesa they do this whole thing in xen to show that the vorts are slaves and don't actually want to fight you, but calhoun never encounters any of that stuff. for the first 2/3rds of xen in this mod, vortigaunts are constantly trying to kill you non-stop. then all of a sudden they don't attack you anymore. why? because i, the player know they're not really bad? why would calhoun know that? it doesn't really make sense to me.
xen is cool. i like xen. if you told me "we're adding more xen to blue shift" i'd be like alright that's cool. but 6-8 times more? that's way too much. xen in blue shift was never meant to be a long trip. calhoun was supposed to get in, find the focal point relay, align it, and leave, not go on a grand alien gallivanting adventure. that's for gordon to do.
