RimWorld: Odyssey introduces **gravships**, advanced technology, and nomadic survival mechanics. This guide explains starting strategies, constructing mobile bases, and thriving while exploring the planet and space.
Getting Started
Gravship Scenario (Recommended)
- Start with a small gravship, three colonists, and basic resources
- Immediate access to **Grav Engine** and gravtech research
- Gather nearby materials to expand your mobile base quickly
- Mechanoid attacks escalate over time – stay prepared to relocate
Standard Progression
- Wait ~6 days for **Mechanoid Signal** quest
- Recover Gravlite Panels and Grav Engine from wreckage
- Research **Basic Gravtech** to unlock shipbuilding
Crafting Your Gravship
- Gravity Field: Blue zone around Grav Engine determines movable structures (red = excluded)
- Substructure Tiles: Build with 1 Gravlite Panel + 4 Steel each (500-tile limit initially)
Launch Requirements
- Thrusters (exit points unobstructed)
- Fuel Tank (minimum 50 chemfuel)
- Pilot Console (assign highest-skilled colonist)
Launch quality depends on pilot skill, system completeness, and thruster alignment – poor prep risks system failures requiring component repairs.
Power Management
- Prioritize **Solar Generators** and **Batteries**
- **Chemfuel Generators** for backup power
- No wind turbines in space – plan energy reserves
- Establish **Biofuel Refineries** for fuel production
Space Survival Essentials
- Build **sealed Gravship Hull walls** for orbital travel
- Space-ready freezer: Cooler vents to vacuum, insulated storage
- **Hydroponics Basins** sustain food/fuel production anywhere
Key Research Goals
- Advanced Hydroponics
- Gravcore Integration (unlocks field extenders)
- High-Efficiency Reactors
Late-Game Expansion
- Complete **Gravcore Quest** to enable larger ships
- Use **Grav Field Extenders** for increased capacity
Nomadic Strategy
- Land briefly for resource gathering
- Optimize compact, modular ship design
- Maintain mobility-focused inventories
FAQ
Q: Fuel requirements for long flights?
200+ chemfuel recommended for interplanetary travel.
Q: Airtight walls required on planets?
Only mandatory for space travel.
Q: Increasing ship capacity?
Gravcore-driven field extenders remove 500-tile limit.
Q: Handling power in orbit?
Solar panels and chemfuel generators only – wind fails.
