Just checked my achievement list to figure out if I was close to meeting any, and I'm positive I should have triggered at least a handful by now (almost completed Storage level, finished Flight Deck and below (except interior of Reactor).

Achievements are definitely busted.

not getting any achievements

The last post was from November 2024, but even in January 2025 the achievements don't work.
Story related achievements like using the code 451 doesn't work as to combat specific ones like blowing 3 enemies with one hand grenade. Work around as suggested here didn't work either.

Hopefully Night Dive does something.
