Buy Galactic Civilizations IV: Supernova Megastructures PC key

Galactic Civilizations IV: Supernova Megastructures is an expansion for Galactic Civilizations IV that lets you build powerful structures to shape your civilization and its place in the galaxy. Each megastructure offers distinct benefits, and choosing what to construct can have major consequences for your empire. Building them requires planning and resource management as your influence attracts attention from rival empires, creating opportunities for diplomacy, alliances or conflict.

Build megastructures

Dyson Spheres draw energy from their host stars to fuel large megastructures. A star’s color determines a Dyson Sphere’s potential energy output, making energy-rich white stars valuable.

The Stellar Nexus serves as your civilization’s core and can be customized with a Nexus Augment. These upgrades give it a powerful new form, with effects determined by the color of its host star. Augments come in three tiers, which indicate the strength and range of their effects.

Stellar Gateways connect distant black holes, opening new options for military movement, rapid expansion and longer trade routes. The Open Gateways Treaty lets fleets from either faction use their respective Gateways.

Ringworlds are colossal Class 39 artificial ring planets that can house large populations. Their host stars’ colors determine their tile bonuses. They provide additional planets for your civilization to inhabit and help secure its future.

Explore new discoveries

New quests and events introduce the expansion’s features. You can discover Ruined Ringworlds and use their ancient technology to advance megastructure engineering. This technology also enables new colony Improvements, new Orbital Improvements and upgrades for existing Orbital Improvements, as well as new ship components for building larger, more powerful ships.
