Default scenario choosing window, with one custom-set scenario.

The scenario system allows you to choose, randomize, and customize special situations to play in. Determine starting situation, type of community (tribe, colony), permanent map conditions, starting items, animals, health conditions, traits, and change special rules. There are 4 built-in scenarios in the game, one of which is the default experience from versions before A14. In the image on the right, you can see the window for choosing scenarios and the "Open Steam Workshop" button (if you are using the steam version of the game).

Default Scenarios

These four scenarios are in the base game. Each offer a different set of challenges, and encourages different playstyles to a certain extent. For example: you could start off as a 'rich explorer' who came from a high-tech glitterworld but yearned to explore the universe, or you could also start as a desperate tribe that's on the brink of starvation after fleeing from a devastating group of 'blood machines'. On the other hand, you could be managing a few crashlanded civilians who barely escaped an assaulted passenger liner with their lives.

Here are the four scenarios listed in order as shown in game:


Summary: Three crashlanded survivors - the classic RimWorld experience.
Description: The three of you awake in your cryptosleep sarcophagi to the sound of sirens and ripping metal. You barely get to the escape pods before the ship is torn apart. Some time later, you land on this unknown rimworld.

Lost Tribe

Summary: Five lost tribespeople attempt to rebuild. Difficult.
Description: Your tribe was destroyed by the great blood machines sent by the gods. Five of you managed to escape. Now, it's time to build up a new home. Note: Since you'll start poor and research slowly, this is a difficult scenario.

  • Start with five people, chosen from eight
    • They will be a 'New tribe'
    • They have a 50% chance of starting with malnutrition
      • Severity ranges from 20% (minor) to 40% (moderate)
    • They have a 100% chance of having a less satisfied 'food' need
      • Satisfaction is set to 0-10%
  • Start with 3 random pets
    • Has a 100% chance of being bonded with random colonists
  • Start with 6 weapons
  • Start with basic supplies
  • Start near basic building materials
    • 500 wood

The Rich Explorer

Summary: One rich explorer out to experience the universe. Extra difficult.
Description: People called you crazy for leaving your glitterworld home, but you always yearned to explore the stars - outside the neurosimulator. Now you're at the end of your long journey in cryptosleep, landing on an unknown rimworld to see what it's like. Note: Since your starting character will lack some skills, this is an especially difficult scenario in the early game.

  • Start with one person, chosen from eight
    • They will be 'New arrivals'
    • Arrive in drop pods
  • Start with one random pet
    • Has a 100% chance of being bonded with the starting colonist
  • Start with technology already researched
  • Start with a high-tech weapon
  • Start with advanced supplies
  • Start near basic building materials
    • 450 steel
    • 300 wood

Naked Brutality

Summary: Naked, alone and utterly unprepared. Can you survive?
Description: You went under anaesthetic for a minor surgery. Now you've awoken in a drop pod crashing into a distant planet. You're naked, alone and utterly unprepared. Can you survive?

  • Start with one person, chosen from eight
    • They will be 'New Arrivals'
  • Start with no items (except for 1 to 2 metal slag chunks from the drop pod)
  • Colonist arrives naked

Scenario editor

Scenario edit mode

The scenario editor looks somewhat like the default scenario choosing window except the left side of the page has changed, there are now three buttons: Load, which you can use to load your previously saved custom scenarios. Save, which is used to save your custom scenarios. And randomize seed, which is used to randomize the scenario. Under these buttons is the Edit mode, which you can toggle to open a window like the one on the bottom-right.
