Top 5 underwater exploration games
From fishing games with a satisfying bite to exploration games where you swim through coral reefs and shipwrecks: only games set on and under the sea. · Updated 2026-10-30
#1 · Underwater survival & exploration
Subnautica: Below Zero
The follow-up to Subnautica, where you explore an ice-covered ocean and follow the story. Shorter and more story-driven than the original, it also works well as a starting point.
#3 · Ocean exploration adventure
Beyond Blue
An exploration game where you become a marine scientist observing whales and sea life. Made with advice from the team behind a real ocean documentary, it makes learning about the sea fun.
#4 · Alien ocean exploration
In Other Waters
A unique game where you guide a biologist stranded alone in an alien ocean, uncovering its ecosystem using only maps and notes. Exploring the sea through text and imagination feels special.
