Somber Echoes is a sci-fi Metroidvania that developer Rock Pocket Games, Lav Games, and publisher Bonus Stage call a “love letter” to the genre. It’s set aboard the Greco-Roman spaceship called Atromitos, where “infested horrors from another dimension” now run rampant. It features seven visually distinct districts and is powered by Unreal Engine 5.
I haven’t played it, but I hear really good things about this retro-3D metroidvania called Pseudoregalia
Looks very inspired by Ocarina of Time, down to the N64-ish graphics. Actually, a few screenshots on Steam could easily be mistaken for Castlevania 64.
