This article is timeless and should be accurate for any version of the game.
- Said Ancient Relics: Collect and acquire valuable relics in your adventures as rewards for overcoming major crises or after completing a dig at an archaeological site and solving the chapters. Each relic gives significant benefits to your empire to aid in your interstellar escapades
- Those Who Came Before: Encounter two new extinct Precursor civilizations, each with their own anomalies. Players can investigate these to understand who they were and, more importantly, what one can learn from their demise.
- Relic Worlds: Once teeming with life, these Relic worlds now lie dead, covered with desolate ruins and dormant mysteries. Players can create archaeological sites to explore these remains and bring to light powerful relics and artifacts.
- Matter of Artifacts: Utilizing archaeological research, discover Minor Artifacts, a new resource type which can help empower one's empire.
- Dig In: Hit the dirt on a variety of enigmatic and alien worlds with more archaeology sites available for your empire to study... or plunder. Each site begins a story with between one and six chapters to investigate. Retrace the history to discover artifacts and relics that can be boons to your empire.
- Prior Content Relic Rework: Many things from previous game content have been reworked to use the new Relics system. Among several others, you can gain the Isolated Contingency Core or the Prethoryn Brood Queen as symbols of your triumph.
- Sector Redesign and Automation: Sectors have been greatly improved in 2.3, allowing the player more control over how and where they are formed, as well as giving more robust automation tools to let them run themselves if you want to focus on the bigger picture.
- Planet Designation: You can now choose to manually set a planet designation (Agri-World, Forge World, etc.), focusing production on different resource outputs. There is now a shared automated development stockpile that you can pay in to and allow planets to set their own build orders.
- Megastructure Improvements: Habitats gain different effects based on the type of celestial body they inhabit. Ring Worlds gain specialized, highly efficient districts.
- 2.3 is now a 64 Bit application. Support for 32 Bits is deprecated, but you can roll back to 2.2.7 if you want to play on such hardware.
- Precursors no longer spawn in a pre-selected pie slice of the galaxy
- Added a menu option at game start to disable Caravaneer fleets if you don't want those sweet, sweet deals
- Added a randomize button when renaming planets
- Rogue Servitors can now build a variant of leisure districts on habitats to entertain their bio-trophies in space
