This Barotrauma tier list ranks every major option by overall effectiveness. Rankings factor in damage output, survivability, versatility, gear requirements, and how well each option scales.
Tier definitions: S = best in class, always a strong pick. A = strong and competitive, minor weaknesses. B = solid but clearly outperformed in most situations. C = viable only for players who enjoy the playstyle.
Builds Rankings
| Tier | Build | Rating | Playstyle |
|---|---|---|---|
| S | Captain | 9.5/10 | Stay at the navigation terminal, chart safe routes through cave systems, call out threats on sonar, and coordinate crew during emergencies. |
| S | Engineer | 9.5/10 | Monitor reactor output constantly, adjust for power demand, repair electrical systems, and prevent meltdowns during combat. |
| S | Medic | 9.5/10 | Craft medical supplies between missions, treat injuries immediately during combat, and manage drug interactions to avoid overdoses. |
| A | Security Officer | 8.5/10 | Man turrets during creature encounters, grab weapons during boarder events, and patrol the submarine for threats. |
| A | Mechanic | 8.5/10 | Respond to hull breaches immediately, weld repairs under pressure (sometimes while the compartment floods), and maintain mechanical systems between emergencies. |
Detailed Builds Analysis
Captain (S-Tier)
The Captain navigates, sets heading, and commands the crew. Good Captains know the cave systems, avoid creature spawns, and manage crew morale. The Captain's navigation directly determines mission success — bad pathing leads to monster encounters and dead ends.
Best with: Navigation terminal, sonar, Captain's uniform (authority bonus) Stat focus: Helm skill, navigation knowledge, leadership
Engineer (S-Tier)
Engineers manage the reactor — the submarine's heart. Reactor output must match power demand: too low and systems fail, too high and the reactor overloads (meltdown). Wiring knowledge lets Engineers fix electrical systems and create custom circuits.
Best with: Wrench, welding tool, wire cutters, diving suit Stat focus: Electrical skill, Mechanical skill, reactor management
Medic (S-Tier)
Medics treat injuries (bleeding, bone fractures, organ damage), cure diseases, and craft medical supplies. The medical system is detailed — wrong drugs cause overdoses, and untreated injuries worsen. A good Medic keeps the crew alive through extended missions.
Best with: Medical supplies, Fabricator access, surgical tools, morphine/antibiotics Stat focus: Medical skill, chemistry knowledge, triage speed
Security Officer (A-Tier)
Security Officers man turrets, fight creatures that board the sub, and handle hostile crew in multiplayer. The Railgun (submarine turret) deals massive damage to creatures. Personal weapons (Revolver, SMG) handle boarders inside the sub.
Best with: Revolver, SMG, Harpoon Gun, Body armor, Stun Baton Stat focus: Weapons skill, reaction time, turret accuracy
Mechanic (A-Tier)
Mechanics repair hull breaches, fix mechanical systems, and maintain the submarine's physical integrity. Hull breaches cause flooding that cascades through the sub. Quick welding repair is often the difference between sinking and surviving.
Best with: Welding tool, wrench, diving suit, hull repair materials Stat focus: Mechanical skill, welding speed, diving ability
Equipment Rankings
| Equipment | Best With | Notes |
|---|---|---|
| Revolver | Security Officer | The standard sidearm for Security Officers. |
| SMG | Security Officer | A rapid-fire weapon with a large magazine. |
| Stun Baton | Security Officer | A melee weapon that stuns creatures and hostile crew. |
| Harpoon Gun | Security Officer | An underwater weapon effective in diving encounters. |
| Railgun | Security Officer | The submarine's mounted turret weapon dealing massive damage to large creatures. |
Equipment Analysis
Revolver: The standard sidearm for Security Officers. Reliable damage against Mudraptors and boarders. Six shots before reloading. The Revolver is the most common personal weapon found at outposts.
SMG: A rapid-fire weapon with a large magazine. Less damage per shot than the Revolver but higher sustained fire rate. Effective against multiple boarders. Ammo consumption is the main downside.
Stun Baton: A melee weapon that stuns creatures and hostile crew. Non-lethal option for subduing infected crew members. The stun effect prevents actions for several seconds, creating windows for injection or restraint.
Harpoon Gun: An underwater weapon effective in diving encounters. The Harpoon Gun works outside the submarine where other weapons don't. Essential for defending divers during exterior repairs or ruin exploration.
Railgun: The submarine's mounted turret weapon dealing massive damage to large creatures. The Railgun requires a dedicated operator and uses the sub's power supply. One well-placed Railgun shot kills Mudraptors and damages Molochs significantly.
Meta Analysis
The current meta in Barotrauma centers on submarine management and crew roles. Builds that leverage both systems outperform those that focus on only one.
What's strong right now:
- Captain with Revolver is the benchmark. Everything else is measured against it.
- crafting builds are gaining ground as players find new synergies.
- Medic remains essential for learning hard content.
What's underrated:
- Engineer is consistently overlooked despite being the most flexible option.
- Stun Baton offers excellent performance for its investment level.
What's overhyped:
- Pure Mechanic builds. High ceiling but the consistency isn't there for most players.
Quick Picks by Situation
| Situation | Best Build | Best Gear | Why |
|---|---|---|---|
| Overall best | Captain | Revolver | Highest consistent performance |
| New player | Engineer | SMG | Most forgiving, teaches mechanics |
| Hard content | Medic | Stun Baton | Survivability when you need it |
| Group play | Security Officer | Harpoon Gun | Utility and team support |
| Experienced player | Mechanic | Railgun | Unique challenge and high ceiling |
