Subnautica 2 – Best Controller Settings

Subnautica 2 had a massive Early Access launch in May 2026, reportedly selling millions of copies within hours. This impressive launch came from Unknown Worlds Entertainment when Subnautica 2 hit Early Access in mid-May 2026. However, sales figures alone won't help players survive the dangers of the deep water, dodge the aggressive Hammerheads, and manufacture an oxygen tank efficiently. Mastering the controller layout is what really matters.

This guide will walk you through everything there is to know about the controller layout for Subnautica 2, updated based on Hotfix 2, along with tips for rebinding and optimizing PC play with a controller.

According to the most recent early access documentation, Subnautica 2 follows a standard shooter layout with specific survival actions mapped to the shoulder buttons. Below is the verified default scheme, noting that some keys (like "Interact" and "Tertiary Tool Use") share the same button depending on context.

While the button layout remains stable, the game world itself has shifted. On May 25, 2026, Unknown Worlds released Early Access Hotfix 2, which changes how players interact with the game using a controller.

One of the first changes controller players will notice is the resource allocation. The developers clearly heard the complaints from gamers about limited access to key resources and added several silver resource nodes to the game's starting area. Troilite is also more common in later areas. Players can now use the Secondary Tool (X/Square) more confidently for scanning and collecting.

Perhaps one of the most aggravating bugs was with regard to the Hammerheads. In previous patches, the Hammerheads had an unnatural affinity for the Tadpole's lights, causing aggressive fish to follow the player to their base camp and not leave.

Strategic Implication: Now the player doesn't have to keep turning around to constantly look behind them (Right Stick). Instead, the Ping (R3/Right Stick) is much more effective for scouting missions without getting stalked.

For players on high-end PCs using "Epic" visual settings, the patch notes confirm a performance boost. This reduces input lag on wireless controllers, making the Primary Tool (RT/R2) response feel snappier.

• Sensitivity: Medium-High
• Aim Acceleration: Off
• Invert Y-Axis: Personal preference
• Vibration: Reduced or off for longer sessions
• Swap Ascend/Descend buttons for comfort
• Disable Steam Input on PS5 controllers
• Enable VRR if supported

The default layout is solid, but Subnautica 2 allows for full customization. A player shouldn't settle for awkward binds.

Because most movement relies on the Left Stick to move forward while using RB/R1 for rising, players may suffer from fatigue. You can rebind buttons in the game's settings menu. Most experienced players suggest swapping the Jump/Ascend (RB/R1) key with the Descend (LB/L1) key, which gives the feeling of crouching, similar to other shooters.

A common issue for DualSense users is seeing Xbox button prompts (A, B, X, Y) in the UI instead of PlayStation symbols (Cross, Circle, Square, Triangle). To fix this:

1. Ensure Subnautica 2 is not running.
2. Open Steam, go to Library, and right-click Subnautica 2.
3. Select Properties, then Controller.
4. Under "Override for Subnautica 2," select "Disable Steam Input."

This forces the game to use the developer's native controller profile, providing accurate button icons.

These controls are only the tip of the iceberg. Unknown Worlds has published its roadmap for summer 2026. Update EA 1.1 is focused on quality of life, including vehicle docking changes (no more issues pressing B/Circle to stop piloting) and a new Sprint button.

EA 1.2 will focus on multiplayer, featuring Voice Chat, Emotes, and Player Reviving. For cooperative divers, learning how to use the Ping system (RS/R3) will be key to planning attacks and resource collection.

Subnautica 2 already offers one of the best controller setups in the survival game category. Thanks to the performance boost from Hotfix 2, the corrected Hammerhead behavior, and easier resource collection, controller gameplay feels better than before. Depending on whether you use an Xbox controller or the PS5 DualSense, you can optimize your ascend/descend bindings and turn off Steam Input. These small adjustments can make underwater exploration, combat, and base-building much more comfortable during long survival sessions.
