Once Upon The Universe patch notes & updates

Military Overhaul - Ships, Customization & Strategic Orders

The military system has received a major overhaul, introducing new warship classes, modular ship designs, expanded combat mechanics, improved fleet management, and new...

Vassalization System

Introduced new vassalization diplomatic actions, allowing stronger civilizations to establish dominance over weaker ones. Civilizations can become vassals through diplomatic agreements or as an outcome of war.

Harbinger Civilization

Do you have a favourite civilization you'd love to see succeed in its quest for interstellar domination? This update has you covered! And who doesn't enjoy playing favourites from time to time? Introducing Harbinger Civilization mode, a whole new way to play!

Special Resources

This update introduces the foundations of the Special Resources system. Unlike raw resources and industrial goods, Special Resources are extremely rare, cannot be traded, and must be discovered and collected through entirely different means.

Civilization Cycle and Population rework

This update is mainly focused on clearing some tech debt and reworking the Population tab UI. Instead of the previous text dump it should be much clearer and easier to read now.

Politics and Vanity

With this update, the second part of the Civilizations Cultures system is being introduced: Politics. A civilization's internal politics now determine how it interacts with its different cultures, how its society is structured and how it approaches other civilizations.

Civilization Cultures

! Civilizations will now create and develop their own cultures based on their early background or colonial origins. Cultures develop additional traits over time, providing unique modifiers to civilizations.

Ice Caps, Sea Levels and Hydrology

Ice caps and water evaporation. With this update, planet land surfaces will no longer have a fixed water-to-land ratio. Instead, it is now actively affected by the level of ice caps on the planet, which will grow and melt depending on the planet’s temperature.

Roads and Ports

! It's an introduction to the planetary logistics system, and the next step toward making each planet feel like a living, breathing entity instead of just an economic data point. With this foundation in place, more planet surface changes will follow soon.

The Big One - Surface update

Time for the Big One. This update adds a new Surface system and greatly expands the early history of civilizations. It is something I wanted to release since day 1. Civilizations no longer appear directly in the Space Age.

Entropy and Megaprojects

In the end, everything drifts toward entropy. The universe slowly loses energy and matter throughout its existence. The only thing that counters entropy is Life.
