Imperium Aeterna Mod Version 2.2.2
For Endless Space Disharmony Version 1.1.58
Imperium Aeterna roughly translates to ‘Eternal Empire’. The aim of this mod is to maintain the vanilla ‘experience’ as much as possible, but to enhance our enjoyment of the game with enhancements and tweaks over time.
This was one of the most popular overhauls of Endless Space, but unfortunately the website I was hosting this on went down and I didn't realise that people could no longer download it. I therefore decided to host it on Nexus Mods instead.
Anyone is free to download, play and use the contents of this mod in their own mods – provided that credits are given accordingly and a link to this Page is added.

- A new Tech Tree, adding 5 new Technologies which each unlock a new System Improvement.
- An overhaul of the Combat Modules, which adds more depth to ship design.
- A Combat Overhaul, removing the vanilla Long/Medium/Short range mechanics and replacing it with a more logical Heavy/Normal/Light set of variants for each weapon.
- Reworked the Ship Classes, so there are now 5 distinct classes instead of minor variations.
- Added ship defense bonuses to Engine Modules – No longer included: Developers added evasion to engines in Vanilla.
- Planet Creation, a new technology near the bottom of the Expansion tree which enables you to terraform Asteroids into Barren planets.
- Planet Size Terraforming, new technologies which enable you to increase the size of planets.
- Gaia Planets and Gaia Terraformation.
- 62 New Anomalies (116 total) and 4 Tiers of Anomaly Reductions.
- A new unique planet “Aeterna”, with its own Wonder, Temple and Events.
- An overhaul of the Diplomatic AI.
- Coloured Anomalies – No longer included: Developers added this in Vanilla.
- Coloured Planet Types – making it much easier to distinguish between the different tiers.
- Coloured Exploitations – making it easier to distinguish between exploitation types.
