Subnautica Free to Play Until April 6

Steam users have the chance to try the iconic survival game Subnautica for free until April 6. This limited-time offer marks the first time the game is available to play for free on Steam. This unique opportunity comes years after Subnautica established itself as one of the most well-known survival games on the platform.

Development and Original Launch

Subnautica was developed by Unknown Worlds Entertainment, a game developer based in San Francisco. The game was first launched in January 2018, after more than three years in early access. Since its launch, the game has gained immense popularity, as evidenced by nearly 175,000 reviews on Steam, with an immersive 96.03% favorable rating. Valve classifies this rating as 'Overwhelmingly Positive'.

The game combines elements of exploration, crafting, and survival in a vast, unknown ocean, where vulnerability, curiosity, and fear are the main themes. Reviewers praise the game's ability to find a unique balance between joy and fear, with an underwater world that can shift from serene, colorful reefs to panic-inducing depths.

Timeline

• Jan 2018: Subnautica launches after more than three years in early access.
• April 4, 2026: Subnautica is available for free on Steam for the first time until April 6.
• March 2026: A Delaware Court of Chancery judge recommends that former CEO Ted Gill be reinstated in the context of Subnautica 2's development.

Promo and Discounts on Steam

Playing Subnautica for free is part of a broader promotion on Steam. The game itself is discounted by 75%, bringing the price down to $7.49, which equals a savings of $22.50. This benefits not only new players but also existing fans of the franchise. The Sub-Sonic Edition, which bundles Subnautica with the original soundtrack, is also discounted by 75% and can now be purchased for $8.98. The sequel, Subnautica: Below Zero, also enjoys the same discount and is now available for $7.49.

This promotion is an opportunity for players who have yet to try Subnautica to experience what makes the game so special within the survival-crafting genre. With its unique approach to world interaction, Subnautica attracts not only gamers interested in survival games but also those looking to immerse themselves in a captivating narrative experience.

Subnautica 2 and Development Issues

In related news, Subnautica 2 is expected to enter early access in 2026. Unknown Worlds initially announced that the delay from 2025 would allow them to respond to feedback from playtesters and further improve the launch. However, the delay is also tied to a broader legal battle between the publisher Krafton and the former leadership of the studio.

In a recent turn of events, a Delaware Court of Chancery judge ordered that former CEO Ted Gill be reinstated and regain full authority over the early access release in March 2026. Krafton previously claimed that Gill, along with game director Charlie Cleveland and studio co-founder Max McGuire, neglected their responsibilities on the project, leading to their dismissal. The ousted executives have disputed that claim and have complained, stating that the publisher dismissed them to avoid a $250 million bonus tied to performance criteria agreed upon during Krafton's acquisition of Unknown Worlds in 2021.

Conclusion

With the free weekend on Steam and the upcoming launch of Subnautica 2, it is an exciting time for fans and newcomers to the franchise. The combination of the current limited-time offer, along with attractive discounts, provides an excellent opportunity for gamers to explore the underwater world of Subnautica. These developments also highlight the growing impact of the franchise within the gaming community and the expectations for future content.
