This article has been verified for the current PC version (3.2) of the game.

An anomaly is represented by survey readings that deviate from what is normal. When a science ship surveys a celestial body it may identify an anomaly that needs further investigation. Anomalies have their own tab in the Situation Log.

When the investigation of an anomaly is complete, an event will pop up that can give various bonuses, such as research points, resources on a planet, or even a special project which requires further research investment to unlock benefits. Certain Ethics occasionally have additional options.

Each surveyed celestial body has a 5% chance of spawning an anomaly, which is increased by 0.5% for every surveyed planet with no anomaly before being reset. The Leader trait meticulous.png Meticulous trait and Menu icon edicts.png Map The Stars edict also increase the chance of finding anomalies by 10%.

Level[edit | edit source]

To investigate an anomaly, a science ship with a scientist on board must be present at the celestial body where the anomaly is located. Investigating them takes time, which is determined by the level of the scientist minus the difficulty level of the anomaly. As such, anomalies of higher levels are often best left off until a skilled scientist can study them faster.

Anomaly list[edit | edit source]

Each anomaly outcome can only take place once. Once each outcome of an anomaly has taken place the anomaly can no longer be found again.

Heavy Readings[edit | edit source]

If an anomaly is randomly discovered on a star and the system contains a Gateway the anomaly will always be the level 2 anomaly Heavy Readings. Investigating the anomaly will issue a special project on the Gateway. Finishing the special project will grant 90-250 Physics Research Physics Research and the investigating scientist will gain 2 skill levels and the Leader trait paranoid.png Paranoid trait.

Repeatable anomalies[edit | edit source]

There are two types of repeatable anomalies. The first is the Ancient Signs of Life anomaly, which can only be found on Planet barren.png Barren worlds and will add the Pm planet from space.pngPm frame 1.png Terraforming Candidate planet modifier once investigated.

The second are anomalies with the name randomized based on the planet class which will reveal a pre-sapient species on the planet once investigated. Such an anomaly can be triggered once for each planet class, including Trait pc gaia preference.png Gaia and Trait pc nuked preference.png Tomb worlds. Civic fanatic purifiers.pngCivic devouring swarm.pngCivic machine terminator.png Genocidal empires cannot discover these anomalies.

Human anomalies[edit | edit source]

If the Sol system is present in the galaxy two special anomalies can spawn. If a human empire investigates them it will gain 40-100 Influence.png Influence.

  • Debris Field anomaly can spawn on a random asteroid. Investigating it will discover the Pioneer 11 probe. If the empire is not human it will bring the following options:
    • Decipher the data disk and gain 500 Engineering research Engineering Research while the science ship leader gains 200 Experience. The location of the Sol system is added to the situation log. Entering the system will grant 80-175 Influence.png Influence.
    • Sell the data disk and gain 500 Engineering research Engineering Research.
    • Use the data disk as furniture and gain 40-100 Influence.png Influence if Xenophobe.png Xenophobe or Fanatic Xenophobe.png Fanatic Xenophobe.
  • A Lush Planet anomaly can spawn on a random Continental or Tropical planet. Investigating it will discover the Voager golden record. If the empire is not human it will gain 350 Engineering research Engineering.
