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.
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.
