Subnautica

Worth buying? What 300 Steam reviews say.

Overwhelmingly Positive2018

The verdict

A landmark underwater survival game with gorgeous biomes, tense thalassophobic horror and addictive exploration. Skip it if you hate grind, vague direction, or having no autosave and no map.

Great for

Players who love atmospheric exploration, discovery with little hand-holding, and a bit of deep-sea horror

Main risk

Vague direction, no map and late-game fetch grind can feel tedious, with save-losing bugs

What players love

Terrifying leviathans and thalassophobia

Late-game grind and tedious travel

Mentioned in ~1 in 5 negative reviews

“The mid to late game, once you have to cover bigger distances, is absolutely horrible. The vehicles are *sooo* slow, and you have to go back and forth soo much.”
