Plan your next Barotrauma session

Our guide helps players master Barotrauma’s layered systems without relying on hidden tricks or paid upgrades. By focusing on core mechanics—crew coordination, resource handling, and strategic choices—you’ll improve survivability and enjoy the game’s rich sandbox potential.

01 / THE GUIDE

Optimizing Crew Composition

Compare runs with different class mixes, noting how the presence of a dedicated Engineer or Medic changes repair speed and injury recovery. Record outcomes to identify the most resilient setups for varied mission types.

  • Coordinate roles early to maximize efficiency.
  • Use bots to maintain crew numbers when friends are unavailable.

02 / THE GUIDE

Resource Prioritization Drills

Run short missions focusing on collecting specific materials first, then crafting essential tools. Track how early resource stockpiles affect your ability to handle unexpected hull breaches or monster attacks.

  • Assign a dedicated Engineer to monitor power and pumps.
  • Let the Medic focus on treating injuries during monster attacks.

03 / THE GUIDE

Faction Alignment Experiments

Play multiple dives aligning with each of the four factions, observing changes in mission rewards, NPC interactions, and overall difficulty. Use the data to decide which alliance best fits your playstyle.

  • Prioritize gathering raw materials early in a mission.
  • Craft spare parts to quickly fix critical system failures.

04 / THE GUIDE

Mod Integration Tests

Install a community submarine mod and a monster mod, then run a standard mission. Note how the new assets influence navigation, combat, and crew workload, helping you gauge the value of specific mods.

  • Explore the Steam Workshop for community‑made submarines.
  • Use the XML files to fine‑tune balance for custom scenarios.

05 / THE GUIDE

Communication Efficiency Practice

Conduct a timed drill where the crew must relay system statuses every minute. Measure how quickly issues are resolved compared to a baseline without structured communication.

  • Maintain good standing with a faction to receive better supplies.
  • Consider the long‑term impact before betraying an ally.
