If you loved FEAR or the newer Wolfenstein games like I did, you'll likely enjoy Selaco too. It takes after those games the most (and even bits of other 2000s FPSs like Half-Life 2) despite getting labelled as a "boomer shooter", being chock-full of secrets/references and running on GZDoom.
The base price of 25 USD might seem a bit steep for an indie title and the game is still in EA, but this is the rare case where you'll get your money's worth in my opinion. The now-released first act (pre-update) is clearly an indicator that the overall design, gameplay loop and vision for the game has been nailed down to a T even if they still semi-regularly update it to tweak it further. From the updates, it also seems they actually have a plan for the next two acts to be released by this century (2025 and 2026 respectively).
That all being said, the story elements (beyond visual story-telling and logs/emails) have been left out for now and there's a big story update coming in by the end of the year so you can also hold off until then.

Fucking amazing, it's FEAR meets DOOM taking place in a massive interconnected space station with tons of secrets all over the place and a bunch of interesting and fun to use weapons
Gross, that's just what I didn't need to hear to protect my wallet
At least right now I have
to play, and then 
before I jump into Selaco
