So after killing more soldiers than I can count, and frankly getting sick of them, I find one of those nuclear warheads, like in Opposing Force. Upon approaching it to disarm, it goes off, but instead of dying, I get teleported to Xen. Only now, I come across some ancient ruins...

It's a mod. That's what the maker included in it.

Residual Life. It's pretty good overall.
If you thought HL Xen was bad, this is sooo much worse. You just run around through caves. It's just dark and wet. Basically a spelunking simulator. Barely any enemies to kill. But... you start finding more weird... ancient alien ruins?
