What is Barotrauma?
Check the opening Campaign of the normal PC game through equipment, AI orders, missions and power, drainage and oxygen displays. Uses the standard Dugong to explain preparation separately for solo and co-op play.
Edition: Normal PC Steam base game, app 602960, without mods. Covers the opening Campaign and basic/job tutorials. Uses the standard Dugong, approximately Normal difficulty and Jovian Radiation off. Distinguishes solo AI from co-op; individual talents, Workshop submarines, the late game and special modes are treated separately.
Verification scope: Public sources compared on 2026-10-04. The latest base-game patch confirmed through official Steam was v1.13.4.0, dated 2026-06-18. Home & Harbor is an upcoming, unreleased expansion. The game has not been launched; the current Japanese UI and reproduction of all wiring have not been checked.

Start with the opening Campaign in the normal game
Barotrauma is a 2D survival game where a submarine travels Europa's ocean and crew handle steering, repairs, defense and treatment. Assigning who will restore which device makes recovery easier to follow than having everyone rush toward the same fault.

| What to check | This article's reference conditions | If yours differ |
|---|---|---|
| Base game and updates | Normal Steam base game; latest confirmed announcement was v1.13.4.0 | Do not mix test-branch, Legacy or mod rules. Match the host's and players' versions too |
| Submarine | Uses the standard Dugong | On Workshop modifications or other submarines, check doors, wiring and backup-power switches |
| Difficulty | Approximately Normal, with Jovian Radiation off | Different oxygen capacity, fuel or failed-repair multipliers change required amounts |
| Progression | Opening Campaign and tutorials | Standalone Missions, PvP and Traitor modes differ in acceptance, carryover and recovery |
| Expansion | Does not assume Home & Harbor | Unreleased on the official store as of 2026-10-04. Do not turn announced outpost ownership into current instructions |

Choose the first display to inspect based on the problem
Wide tables scroll horizontally.
| Problem | Current situation | Check first | Article to read |
|---|---|---|---|
| Cannot breathe even with a suit on | Equipment is visible but you cannot breathe | Tank name and remaining contents inside the suit | Beginners: breathing equipment |
| Cannot repair a wall | Aiming the tool does not make progress | Welder fuel and whether the target is hull or machinery | Beginners: choosing the repair method |
| AI does not repair | The order is displayed | Order priority, tools, access route and chat | Beginners: AI orders |
| Mission does not begin on departure | You heard about it at the outpost | Route and checked mission entries | Campaign: acceptance and selection |
| Devices stop all at once | Stopped in multiple compartments | Reactor Power, fuel and connected equipment state | Systems: submarine-wide power loss |
| Submarine will not rise | Sinks despite steering | Water levels outside ballast compartments and hull damage | Systems: drainage and buoyancy |
| Water will not drain | You thought you fixed the hole | Other holes, open doors and the pump's Power light | Systems: pump displays |
| Turret moves but will not fire | Only the aiming works | Ammo in the corresponding Loader and Supercapacitor charge | Systems: defense chain |
| Results differ after returning to port | You reached the destination | Incomplete mission display and the actual target item | Campaign: completion and return |

Jobs are specialties; other jobs can take over normal repairs
Jobs change starting skills, gear and talents, but the job title alone does not make all normal repair or steering impossible. Consider required tools, skills and access permissions separately.
Wide tables scroll horizontally.
| Example main role | Routine assignment | Check when someone is absent |
|---|---|---|
| Captain | Manage route and position at the Navigation Terminal | Assign a replacement helmsman rather than adding people who steer independently |
| Engineer | Maintain the reactor and electrical systems | Check the Screwdriver, Electrical skill and power system |
| Mechanic | Hull breaches and pump/machinery maintenance | Prepare a Welding Tool and Wrench separately |
| Security Officer | Turrets and intruders inside the submarine | Check turret assignment, firing arc and ammunition. Do not fire at allies outside |
| Medical Doctor | Diagnose and rescue injured crew | Report the condition and choose a treatment lead before stacking medicines |
| Assistant | Help with unfilled tasks | Start by carrying supplies and checking quantities, then bring the necessary tools to support specialists |

Talent-unlocked recipes and unique effects are not treated as shared by everyone. Co-op requires player assignments; solo requires AI order settings.
For your first trip, prepare a submarine that can depart and equipment that can bring you back
- Try selecting devices, repairing and replacing breathing tanks in basic/job tutorials. Enabling Tutorial at the start of a solo Campaign also introduces accepting missions
- Walk through the Dugong to locate the command room, reactor, junction boxes, oxygen generator, suit lockers, airlock and turret periscopes
- Open each person's tools and tanks and check remaining contents. Supplies in a crate and a usable item currently equipped are separate checks
- Assign steering, repairs and defense. In solo, check the order beside each crew name; in co-op, confirm a response
- Read the selected route and missions. If work outside is needed, decide who goes and who stays. Reduce the mission count before departure if underprepared
The Dugong normally has no Fabricator, Medical Fabricator or Deconstructor. Prepare at outpost facilities or shops instead of assuming you can always craft missing supplies underway.
Combine alarms, the Status Monitor and crew reports
There are clues to faults. Check the Dugong's alarms, reactor warning lights, Status Monitor and AI chat, then communicate who should go to which compartment. A single alarm may not identify the cause.
Wide tables scroll horizontally.
| Clue | What to read | Example report |
|---|---|---|
| Status Monitor／General Status | Compartment name, water level, hull damage and any available oxygen reading | "Engine room flooding. Mechanic: check the hole. Engineer: check electrical equipment." |
| Electrical View | Fault locations and electrical condition | "The upstream junction box is stopped, rather than just the pump." |
| Reactor warning | Check heat and output separately | "Temperature is high. Do not add fuel rods on your own." |
| AI chat | Missing tools, unreachable destinations or no target | "Return the spare Welding Tool to the shared locker." |
| Crew outside the submarine | Position, oxygen remaining and return route | "Returning to the airlock. Keep the turret's line of fire clear." |

Available readings depend on the submarine's sensors and connections. Missing numbers do not mean safety has been confirmed. These example callouts were written for this guide.
When older guides look different
Wide tables scroll horizontally.
| Topic | Checked difference or caution | This guide's approach |
|---|---|---|
| Standard submarine layout | Tier 1 submarines and five other submarines were revised in 2026 | Do not treat old room locations or wiring diagrams as correct for every submarine |
| Sending crew outside | An older personal guide forbids it across the board; a newer guide distinguishes Wait and Follow | Check routes, equipment and who remains aboard. AI success is not guaranteed |
| Supply sources | Onboard crafting facilities vary by submarine | Do not require crafting underway on the Dugong |
| Existing warning explanations | The game does not automatically handle every danger, but alarms exist | Replace this with specific monitoring and communication methods |
| Future expansion | Home & Harbor is unreleased on the official store | No instructions for unlocking outpost management or new factions |

These four articles cover early controls and diagnosis. They do not comprehensively cover every mission, every submarine's wiring, the ending or optimal talents.
