Dungeons of DUSK has been announced from New Blood Interactive. It's a retro dungeon crawler set canonically between the episodes of the classic FPS DUSK. How exactly does it fit in? According to New Blood it "starts right after the end of Episode 1 of DUSK. Literally".

It's a "proper RPG" too with skills to unlock, passive bonuses, NPCs to help you along the way and multiple different game modes to crawl through. Interestingly, they also confirmed that the inspiration behind the game was DOOM RPG, a 2005 mobile game from Fountainhead Entertainment.
