RimWorld Odyssey Map Size Guide

In RimWorld Odyssey, map size is set during world/map generation and applies to where your gravship lands. You can’t change it mid-game for your current tile, but there are a few ways to control or modify it before landing.

How Map Size Works in Odyssey

By default, Odyssey uses the same map size settings as the base game. When you create a new world or start a new colony, you’ll be able to choose map size under the Advanced options. The standard options are generally:

• 200x200 (small)

• 250x250 (medium, default)

• 300x300 (large)

• 325x325 or 350x350 (custom, if allowed by mods or manual config)

For gravship playthroughs, every map your ship lands on will use the default map size unless changed.

How to Change Map Size for Odyssey

1. At World Creation
   Use the Advanced options when starting a new game. This will affect every map tile your gravship enters.

2. Mod Tools (If Available)
   Mods like Rocketman or Map Designer allow you to set map size for future tiles. As of now, Rocketman may not be updated for 1.6, so check compatibility before using it.

3. Custom XML Editing (Advanced Users)
   You can manually edit RimWorld’s defaultMapSize in the ModSettings XML files, but this affects all saves and may break compatibility with Odyssey or gravship-specific features.

4. No In-Game Option Mid-Run
   There’s no way to resize a map you’ve already landed on. Only the next map tile you enter will reflect any size change if you’re using a mod that supports it.

Best Size for Gravship Play

• Medium (250x250) works well for most landings

• Large (300x300+) gives more salvage space, but increases lag

• Smaller sizes are faster to load but limit room for building around large POIs

Landing on asteroids, derelict bases, or orbital stations uses preset sizes. You can’t customize those maps.

Final Blurb

Map size in RimWorld Odyssey is locked in at world creation. If you want more space for your gravship landings, pick a larger map size before you begin. Mods may help tweak it later, but you won’t be changing your current tile.
