Explore the RimWorld Anomaly DLC's terrifying new threats, including entities, containment, psychic rituals, and the mysterious monolith. Survive the horror!

Walkthrough
  1. 1
    The Monolith: This structure appears at the start or after the 'Strange Signal' quest. Investigating it activates it, increasing its level and allowing more dangerous entities to appear. There are 3 levels, requiring discovery of specific entities to advance.
  2. 2
    Entities: These are the primary threats. Most appear after the monolith is investigated. They can be studied by incapacitating them and placing them in containment cells, advancing the Anomaly Tech Tree.
  3. 3
    Entity Codex: Discovering entities unlocks entries in this codex. Higher monolith levels spawn more dangerous entities.
  4. 4
    Studying Entities: Incapacitate an entity and place it in a containment cell. Colonists will use the 'Dark Research' job to study them.
  5. 5
    Monolith Levels: Level 1 requires discovering 8 entities. Level 2 requires discovering 7 out of 8 level 1 entities. Level 3 requires discovering 12 out of 17 level 1 or 2 entities.
Tips
  • The 'Ambient Horror' setting allows Anomaly content without the monolith being the focus, but the monolith endgame is not possible.
  • Anomaly threat frequency can be adjusted in custom difficulty settings (default: 8% inactive, 30% active). These sliders do not affect minor incidents.
  • The DLC was released on April 11, 2024, and is inspired by horror classics.
