If you’ve ever found yourself stuck 800 meters deep in Subnautica, oxygen running low, Seamoth out of power, and no way up, you’re not alone—and you’re not without options. That’s where game codes come in. In plain terms, game codes (or console commands, as the devs call them) are shortcuts built into the game’s backend—originally for testing, now used by players who know how to bend the world to their will. These aren’t mods or third-party hacks; they’re built-in features available on the PC version, and accessible on Xbox and PlayStation with a few extra steps.
Most people who use these aren’t trying to “cheat”—they’re unlocking a sandbox experience. In Creative Mode or Debug Mode, survival mechanics like oxygen levels, hunger, and crafting limitations are optional. Think of it like switching from survival to architect mode. Want to build an underwater base in the lava zone without dying every five minutes? That’s a job for console commands. The Subnautica console guide community has grown steadily since launch, and according to SteamDB, over 1 in 3 players activate cheat codes at least once during their second or third playthrough.

How to Redeem Codes in Subnautica (All Platforms)
Redeeming cheat codes in Subnautica isn’t exactly front-and-center — it’s tucked behind a few UI layers depending on your platform. If you’re on PC, you’ll want to hit F3, then tap F8 to unlock your mouse. Uncheck “Disable Console”, hit Enter or ~, and you’re in. Console players (on Xbox or PlayStation) have it a bit different. There’s no typed interface, but you can still use a debug menu by pressing a specific button combo: L1 + R1 + Square + X on PlayStation, or the Xbox equivalent. Once that overlay opens, cheats work similarly, though with a bit more fuss.
The command prompt acts as your gateway — type commands like item seaglide 1 or oxygen to trigger them instantly. These aren’t just cosmetic changes; they directly inject items into your inventory or change the game state. Especially if you’re testing something or just want a more relaxed experience, this can seriously change the pace.
Common Issues When Codes Don’t Work
Let’s be real — most “broken” cheat code complaints boil down to typos or missed steps. If you’re typing in commands and nothing’s happening, double-check the spelling, spacing, and whether the console is actually active. For example, itemseaglide1 won’t work, but item seaglide 1 will. It’s picky — that’s just how the engine’s built.
About 1 in 3 help threads on the Subnautica Steam forums are about this kind of mistake. Another hidden pitfall? Some commands only work in Creative Mode. So if you’re in Survival, the game might silently ignore what you’re trying to do. A quick switch via gamemode creative can fix that immediately.
Here’s a quick rundown of troubleshooting tips:
- Nothing happens after typing? Console likely isn’t active or you mistyped.
- Code works, but item doesn’t show up? Inventory may be full or the item spawns outside your view.
- Console not opening? Try different keybindings or reset your config
