In RimWorld Odyssey, your chosen map size determines the playable area when landing a gravship. This setting is locked during world/map generation and cannot be altered for existing colonies mid-session, though adjustments can be made before deployment.

Map Size Mechanics

The expansion uses the base game’s map size system. During world creation or colony setup, select from these options under Advanced settings:

• 200×200 (compact)
• 250×250 (balanced, default)
• 300×300 (spacious)
• 325×325 / 350×350 (modded/custom configuration)

Every gravship landing adheres to this preset size unless modified by external tools.

Adjusting Map Sizes

1. Pre-Game Configuration
   Set your preferred size in Advanced options before starting a new game. Affects all subsequent landings.
2. Mod Support
   Modifications like Map Designer can override future landing zones. Verify compatibility with version 1.6 before installation.
3. Manual XML Edits
   Advanced users may alter the defaultMapSize value in game files, though this risks compatibility issues.
4. No Mid-Campaign Changes
   Current maps remain fixed. Mods can only adjust upcoming landing zones.

Optimal Map Sizes

• Medium (250×250): Ideal for performance and base-building flexibility.
• Large (300×300+): Expansive for salvage operations, but may cause lag.
• Small (200×200): Faster loading at the cost of limited space near Points of Interest.

Note: Orbital stations, asteroids, and derelict sites have fixed, unalterable map sizes.

FAQ

Q: Can I resize maps mid-campaign?

No—existing maps remain static. Adjustments apply only to new landings.

Use the Advanced tab during world creation.

Q: Does Odyssey introduce unique map sizes?

Only for specific locations like space stations, which are preset.

Q: Recommended mods?

Mods like Rocketman (if updated) enable post-launch adjustments.

Q: Ideal size for gravship builds?

250×250 balances space and performance. Larger maps require robust hardware.
