Keep in mind that if building a Gateway you can’t build it in a gravity well, you’ll need to choose a spot outside it, something you can’t do using the method above. Select he Build megastructure option that appears on the pop-up, then click on the megastructure you want to build.Īnother method, and one that you’ll need to use if building a Gateway, is to select a construction ship, zoom into the system and right-click, then chose build megastructure from the option list that appears. Probably the easiest way to build one is to select a construction ship, zoom into the system you want to build in, then right-click on the planetary body or star that you want to build at. There are a couple of ways to build megastructures. Habitats cannot be built around a star or minor planetary body. Choose a spot outside the red zone and left click. The gravity well will be highlighted in red, indicating the Gateway can’t be built in that area. Instead, after selecting a construction ship, click on the Build Megastructure icon, choose Gateway, then zoom into the system you want to build it in. If you select a construction ship then right click on a planet or star you won’t be able to build one, the tool tip says you can’t build it in a gravity well. Gateways can’t be built in gravity wells so building one is a little different from the other ones. They can’t build at an unsurveyed or habitable planets, at a star of any type, and they can’t be built at an asteroid or moon. The exact opposite is true for a Matter Decompressor when it comes to stars, they can only be built around black holes.Ī Science Nexus, Sentry Array, Mega Art Installation, Strategic Coordination Center, and Interstellar Assembly must be built at an unhabitable planet. They both render any planetary bodies in the system worthless, either by turning them into frozen wastelands or by pulverizing them. They must be built in systems with a single star (no black holes). Ringworlds and Dyson Spheres need to be built in systems without any habitable planets and there can be no mining or research stations. Where to build megastructures depends on what you want to build.
Megastructures can’t be built at small planetary bodies like moons or asteroids, and if there are research or mining stations in the system they will generally need to be dismantled first.įor more on how to play Stellaris check out our 101 Beginner’s Tips page. Generally, you can only build one megastructure per system unless it’s a Gateway or Habitat. You can only have one megastructure of each type with some exceptions that are discussed later on this page. There are also some things to keep in mind when it comes to requirements. The Gateway Activation Technology must be completely researched before you can build or reactivate a Gateway.
For example, Habitats require Orbital Habitats Technology to be completely researched. What’s needed is the technology researched by the same name for each megastructure.
Initially you can only have one of each type plus you can only have one per system unless it is a Gateway or Habitat. You must use a construction ship to build one. Unfortunately, any planets in that system turn into frozen wastelands. For example, a Dyson Sphere is constructed around a star to tap all its energy for your empire’s use. Ever wonder what the requirements are to build a megastructure? Stellaris megastructures are titanic structures that give an empire specific bonuses.
