New Megastructures DLC is now available for Galactic Civilizations IV, adding the chance to go all Francis Ford Coppala on some structures in the sci-fi 4X strategy game. The DLC is available on the Official Website, the Epic Games Store, and Steam, though care should be taken not to purchase this a second time, as it's part of the Season Pass. It adds endgame content, including Dyson Spheres, Stellar Gateways, Ringworlds, and other fantastic theoretical structures. There's news for owners of the base game as well, as this gets a free version 2.92 update with new content for all, adding improved Galaxy Map generation, a simplified Galaxy View, updated lighting effects, and more. Here's the Megastructures Expansion Trailer with a look, and here's more:

The pinnacle of technology, Megastructures are powerful structures capable of tipping the cosmic scales in your favor. Each Megastructure has something unique to offer and your decision on which to build can have drastic implications.

Dyson Spheres are the ultimate energy engines that drive your civilization’s evolution through fueling massive Megastructures that redefine your empire. The color of a Dyson Sphere’s host star dictates its potential Energy Output making Energy-rich white stars a valuable resource.

The Stellar Nexus will be the core of your civilization and can be customized to become a Megastructure with many possible powerful benefits. A Stellar Nexus can be upgraded into a powerful new form by installing a Nexus Augment. These Nexus Augments provide various potent effects based on the color of the Nexus' host star and are divided into three tiers denoting the strength and range of their effects. Which Augment will you build?
