Throughout the galaxy are scattered Archaeology map icon.png Archaeological Sites, areas where remains of ancient civilizations have been preserved relatively intact. They can be discovered while surveying, generated at game start, or uncovered a few years after a planet is colonized.

Mechanics[edit | edit source]

Archaeological Site

Most archaeological sites are revealed by surveying, with a 1.23% chance of creating a site, if the celestial body can support one. If a site is created this way, the chance is reduced to 0.25% for 5 years. Unlike anomalies, each time a celestial body is surveyed, a archaeological site can be created. Some archaeological sites are specifically created by anomalies, origins, special projects, other archaeological sites, or events. Most archaeological sites are visible to all empires once discovered, while a few are visible only to the discovering empire. The presence of an archaeological site is visible both in the system and galaxy view with this icon: Archaeology map icon.png. If a system contains more than one archaeological site, clicking the icon on the galaxy view will cycle through the sites.

An archaeological site can have 1-6 Chapters in addition to an introduction chapter. Each chapter has its own narrative and rewards and has to be unlocked before it becomes visible. Chapters are unlocked via Excavation. As long as an archaeological site is within an empire's borders, that empire can task a Science Ship with an assigned scientist to excavate the site. Excavation proceeds in phases, each taking Time 90 days. This time is affected by the following:

Time Excavation Speed Source Modifier
Ancient Relics.png Leader trait archaeologist.png Archaeologist +25%
Leader trait percussive maintenance.png Percussive Maintainer +10%
Leader trait traumatized.png Traumatized −30%
Regular AI empires −50%

At the end of each phase, a die is rolled, resulting in a random number from 1 to 10; adding the current number of clues and the Scientist's archaeology skill (see table below) and subtracting the chapter's difficulty gives the total result, as in the following formula: .

Archaeology Skill Source Bonus
Per Scientist.png Scientist level +1
Leader trait psionic leader.png Psychic +1
Leader trait psionic chosen one.png Chosen One +2
Ancient Relics.png Tech archeology lab.png Curator Archaeology Lab +2

A result of 14 or greater completes the current chapter; a result of 11-13 adds 2 clues for the next phase, a result of 6-10 adds 1 clue, a result of 5 or less adds no clues and can trigger various events, depending on the archaeological site and chapter.

Excavation can be paused and resumed at any time with no penalty. If the system with the archaeological site is gained by another empire, that empire can continue the excavation from the current chapter, but does not gain any rewards from already completed chapters.

Many chapter rewards are a number of Minor artifacts.png minor artifacts; as these are only available with the Ancient Relics.png Ancient Relics DLC, sites which do not require that DLC may have an alternate reward or no reward for chapter without it.

If an empire is part of a Federation research.png Research Cooperative, then fully excavating any archaeology site has a 10% chance to start the event chain which reveals this site. Each member of the federation receives the site if a suitable system and planet exists within their borders, otherwise the member is given two special projects to support their federation allies with sites. Federation members can also opt not to participate.
