RimWorld Odyssey Starting Scenario Guide

The primary starting scenario in RimWorld Odyssey, The Gravship, introduces players to the DLC’s mobile base mechanics. This scenario begins with a small spacecraft equipped with early Gravtech, limited colonists, and essential supplies. You can play it as designed, modify its parameters, or create entirely new scenarios using the built-in editor.

Default Gravship Scenario Overview

This setup provides a balanced challenge with:

A minimal crew of colonists
A functional Gravship base
Preliminary Gravtech research completed
Pre-installed ship components (engine, thrusters, fuel tank, and control console)
A compact map with salvage opportunities
An ongoing mechanoid pursuit creating time pressure

The mechanoid chase encourages strategic mobility and efficient resource management. To disable this threat, simply remove the event from the Scenario Editor while retaining other features.
