A coworker showed me a trailer some years back. It was first person view, maybe horror, sci-fi setting like a ship/space station with flesh the colour and texture of an eye socket growing over everything. There were other elements modeled after body parts, like bones, teeth, intestines, etc.
not really a ship, but otherwise a “closed ecosystem” in Stray, https://static.wikia.nocookie.net/stray/images/0/04/Sewer_Zurk_Substance.png/revision/latest?cb=20220728192618 , maybe?
edit: some more pics here https://stray.fandom.com/wiki/Fleshy_Walls#Gallery
edit2: not really first person, but topdown adventure/scifihorror: stasis, cayne and stasis: bone totem? IIRC all deal with space-stations being infected by something that merges peopleparts to walls and such
edit3: also, Warframe’s infested missions have spaceships infested with “eyes”/dangly things - not really first-person but it fits the timeframe better
