Deal | Subnautica just got its biggest ever discount on Steam
You don’t need to know all the deep-sea lore to get into this game. Subnautica is an action-adventure survival game from 2018 that drops players onto an alien ocean planet after their spaceship crashes. You play as Ryley Robinson, diving into underwater landscapes full of strange creatures, lush biomes, and hidden secrets. Your goal? To gather resources, build tools and bases - including submersibles - and figure out how to get off the planet alive. Managing food, water, and oxygen adds an element of stress and tension to every dive, and while the game is more about survival, it keeps things open-ended and immersive rather than mission-driven.
Now for the deal: Steam has Subnautica listed at 75% off, bringing the price down to just $7.49 - and that’s the lowest it’s ever been on the platform. There's a bundle deal as well, the "Sub‑Sonic Edition," which includes the game plus its soundtrack - also slashed by 75 percent off.
If you’re new to the game or thinking twice, here’s why so many players rave about it. It’s earned praise for its atmosphere and exploration. One Steam reviewer put it simply: "It is really immersive and illustrates the feeling of being stranded by yourself, in an alien planet, perfectly." They also added that encountering a silhouette of a giant sea creature in the pitch-black depths "really rattled my bones". On Reddit, fans gush over its replay value all the time. In the words of one user: "Replayability is above average as you're sure to find new things in second, third even fourth playthrough."
Critics were just as positive. PC Gamer described Subnautica as an "underwater Minecraft". MeriStation described how the ocean feels alive, thanks to its vibrant flora and fauna and the thrill of discovery, even if there are some optimization hiccups (that are mostly fixed now).
Beyond reviews, Subnautica also impressed the awards circuit. It won PC Game of the Year in the 2018 Golden Joystick Awards, took home Breakthrough Award for developer Unknown Worlds, and was named Fan Favorite Indie Game at the Gamers’ Choice Awards. It racked up several other nominations too, from visual and audio design to game design challenges
If you’re after a game where exploration feels thrilling, survival mechanics keep things grounded, and the environment tells a story without constant hand-holding, this is a perfect time to dive in (pun intended). Check it out here. Additionally, there's a 75% discount running on Subnautica Below Zero as well - read more about that here.
