Large Caves

I would love caves like the lost river where its a gigantic cave with a celing. Even if some places in subnautica 2 is deep they dont feel scary because they are not dark and has just alot of visual space. If you instead would make a cave like that lost river but even bigger and darker like the beginning area of subnautica 2 that is really dark and empty. the thought of not seeing the walls, floor and celing is scaring me and i want it.

This is the one thing I’m hoping is NOT in Subnautica 2. I always liked the deep dark ocean and not some cave :(
