This Subnautica 2 Xbox Game Pass guide covers exactly which tiers include the game, how cross-save works between Xbox and Windows PC, the download size for Xbox Game Pass users, and how to play Subnautica 2 Xbox Game Pass co-op with friends who own the game on different platforms. Understanding Subnautica 2 Xbox Game Pass details helps you maximize your subscription value.

Which Game Pass tiers include Subnautica 2?

Subnautica 2 Xbox Game Pass is available on three tiers: Game Pass Ultimate ($19.99/month), Game Pass Console ($11.99/month), and PC Game Pass ($11.99/month). The Subnautica 2 Xbox Game Pass inclusion on Ultimate provides the most flexibility since it covers both console and PC play along with Xbox Cloud Gaming (xCloud) access. If you subscribe to the Console tier only, Subnautica 2 Xbox Game Pass access is limited to the Xbox Series X|S version. PC Game Pass subscribers get Subnautica 2 Xbox Game Pass access through the Microsoft Store version on Windows 10 and 11. The Subnautica 2 Xbox Game Pass deal does not require a Core tier subscription — the base Game Pass Console tier is sufficient on Xbox, though multiplayer requires an active Xbox Game Pass Core or Ultimate subscription for online play on console. On PC, Subnautica 2 Xbox Game Pass multiplayer does not require additional fees.

Cross-save and progression

Subnautica 2 Xbox Game Pass supports cross-save between Xbox Series X|S and Windows PC when using the same Microsoft account. Your Subnautica 2 Xbox Game Pass save files sync automatically through Xbox cloud saves, allowing you to continue your base and story progression on either platform. This cross-save feature for Subnautica 2 Xbox Game Pass works seamlessly for Ultimate subscribers who switch between console and PC. The save file size for Subnautica 2 is approximately 50–200 MB depending on base size and exploration progress, and Xbox cloud save storage has a 10 GB limit per account that is unlikely to be reached. Note that Subnautica 2 Xbox Game Pass save files are not compatible with the Steam version — the Subnautica 2 Xbox Game Pass ecosystem is separate from the Steam ecosystem. If you start on Subnautica 2 Xbox Game Pass and later buy the Steam version, you will have to start fresh.

Playing with friends on Game Pass

Subnautica 2 Xbox Game Pass co-op works between any players on the Microsoft ecosystem. A player on Subnautica 2 Xbox Game Pass (Xbox console) can invite a friend on PC Game Pass and vice versa. However, Subnautica 2 Xbox Game Pass players cannot play with Steam owners — the Subnautica 2 Xbox Game Pass network is isolated from the Steam network. If your co-op group includes both Subnautica 2 Xbox Game Pass users and Steam users, the simplest solution is for all players to use Subnautica 2 Xbox Game Pass on the Microsoft store. Inviting friends in Subnautica 2 Xbox Game Pass uses the standard Xbox Live friends list and party system. The Subnautica 2 Xbox Game Pass version also supports Xbox Play Anywhere, meaning a single purchase (or subscription) gives you both the Xbox and PC versions. Since Subnautica 2 Xbox Game Pass is included with the subscription, this effectively gives you both versions at no extra cost.
