Rust Submarine Controls
Shift surfaces, Ctrl dives — and Spacebar is the mistake that drowns people.

| Spacebar | Dismount — yes, even underwater. See below. |
Before it moves
Fishing Village vendors sell both: Solo 200 Scrap, Duo 300. Low Grade Fuel — the Solo's tank is external at the rear, the Duo's is inside, reached from the passenger seat. The keys are identical between the two; the Duo adds torpedoes and a second seat.
What goes wrong
- !The classic fatal error: pressing Spacebar to go up. Spacebar EJECTS you into open water; Shift is the ascend key.
- !Submerging starts a 10-minute hull-air timer above your health bar. When the submarine icon flips to a lung icon, the hull oxygen is spent — surface or find a moon pool.
- !The Solo has no weapons at all. If you're being hunted, your options are depth and land.
