About Cosmoteer: Starship Architect & Commander

Cosmoteer lets players design and command starships in a physics‑driven universe. Using intuitive ship‑creation tools you can shape hulls, place modules, and manage crew whose efficiency affects combat performance. The game features a procedurally‑generated galaxy where you take contracts, earn loot, and upgrade your vessels.

Play solo, with friends in co‑op, or test creations against others in PvP. Creative Mode offers unlimited resources for unrestricted building, while a robust modding framework and Steam Workshop keep content fresh. The Windows‑only title supports a range of accessibility and quality‑of‑life features.

01 / THE GUIDE

Ship Design Tools

The builder lets you fully customize a ship’s shape and floor plan, placing individual modules such as weapons, engines, hallways, and crew quarters. Design choices directly influence performance in battle, making each ship unique.

Modules are arranged on a grid, and the system is described as easy to learn but hard to master, encouraging experimentation and iteration.

  • Start with a balanced layout of power and thrust before adding heavy weaponry.
  • Use the workshop to view community designs for inspiration.

02 / THE GUIDE

Crew Simulation

Each ship houses from a few dozen to over a thousand individually‑simulated crew members who pilot, operate weapons, and handle munitions. Their efficiency determines how well the ship performs in combat.

Crew behavior can be customized with specific roles and job priorities, though they also act autonomously.

  • Assign roles that match module functions to improve overall efficiency.
  • Monitor crew performance during battles to adjust priorities.

Combat Mechanics

Battles are real‑time and physics‑driven, with each module individually targetable and destructible. Ships can break apart into multiple pieces when critical components are destroyed.

Tactics include targeting enemy weapons, shields, or reactors to reduce offensive capability, defenses, or to finish the fight.

  • Focus fire on enemy weapons first to limit retaliation.
  • Watch for structural damage that could cause a ship to split.

04 / THE GUIDE

Game Modes

Players can explore a procedurally‑generated galaxy solo, take contracts for factions, or team up in online or LAN co‑op. Multiple PvP battle modes let you test ships against other players.

Creative Mode provides unlimited resources for unrestricted building, allowing experimentation without resource constraints.

  • Try co‑op first to learn ship strengths before entering PvP.
  • Use Creative Mode to prototype designs before committing resources.

05 / THE GUIDE

Community & Modding

Cosmoteer supports a powerful modding framework and Steam Workshop, enabling player‑created weapons, modules, and enhancements. The community is active on Discord with over 20 k members.

Designs can be shared through the Workshop, Forums, and Discord, keeping the game fresh with new content.

  • Browse the Workshop for balance‑tested modules before installing.
  • Join the Discord to get feedback on your ship designs.
