RimWorld Odyssey Vacsuit & Vacuum Barrier Guide

RimWorld Odyssey Vacsuit & Vacuum Barrier Guide

Written by Alec Blackwood

Vacuum exposure in RimWorld Odyssey poses an immediate lethal threat to unprotected colonists. Survival requires either **Vacuum Barriers** to create sealed environments or **Vacsuits** for personal protection. This guide breaks down both systems and their optimal use cases.

Understanding Vacuum Mechanics

Found in space biomes like derelict stations, vacuum instantly drains oxygen from unprotected pawns. Standard armor or clothing provides no defense—colonists will collapse within seconds and die shortly after.

Essential Survival Strategies

  • **Primary Solutions**
    • Equip **Vacsuit + Vacsuit Helmet** combo
    • Construct **Vacuum Barriers** paired with Gravship Walls and Oxygen Pumps

*Most colonies use both systems: suits for mobility, barriers for base security.*

Vacuum Barrier Essentials

These structures create pressure-sealed zones for airlocks, emergency rooms, or leak repairs.

Requirements:

  • Unlocked via **Orbital Tech** research
  • Construction Skill: 6+
  • Materials:
    • 40 Steel
    • 2 Components
    • 2 Gravlite Panels

Deconstruction Returns:

  • 20 Steel
  • 1 Component
  • 1 Gravlite Panel

*Note: Barriers block vacuum but don’t generate oxygen—pair with pumps.*

Vacsuits: Mobility in the Void

These heavy suits provide universal vacuum protection at a movement cost:

  • Reduces speed by **-1.25 c/s** (scales with pawn’s Moving stat)
  • **Critical:** Helmets are mandatory—partial gear offers zero protection

Tactical Applications

  • **Vacsuits** for:
    • Salvage operations
    • Combat in vacuum zones
    • Emergency rescues
  • **Barriers** for:
    • Airlock systems
    • Permanent base structures

*Never use only one system—suits deplete during sieges, barriers can breach.*

FAQ

Q: Do I need both a Vacsuit and a Helmet?
Yes. Partial gear provides no vacuum protection.

Q: How do I unlock Vacsuits and Barriers?
Research **Orbital Tech** to access both simultaneously.

Q: Can I survive with only barriers?
Only within sealed, oxygenated zones. Outdoor work requires suits.

Q: Do Vacsuits handle extreme temperatures?
Yes—excellent cold resistance, moderate heat protection.

Q: Are barriers reusable?
Yes. Deconstructing returns partial materials.
