Grimcave
Dive site
Verification status
This entry comes from community-observed gameplay footage and has not been confirmed by the developer. Its exact name or stats may differ in-game.
Overview
Grimcave is the dive site added with the Grimcave update, announced live on the official Discord on 2026-09-22 ("GRIMCAVE UPDATE IS LIVE NOW! ... One? new map!"). The community wiki describes a spacious cave filled with tall rock pillars and lightly glowing blue material, with light poles that flash red every few seconds — and multiple symbols written on its walls and floors, hints that intelligent beings used to live here. Watch the pillars: Crownspines can hide behind them, and the site is prone to Grimreefs and the Dread Whale. A hidden item somewhere in the cave leads to a secret area called The Drop-off. No official depth has been published; since the September 23 patch, all maps can be unlocked before level 10.
