巨型结构

Humanoid Empire constructing a Dyson Sphere

Megastructures are colossal constructions. Expensive and time-consuming to build or repair, these remarkable feats of engineering are nonetheless important wonders that provide large bonuses, demonstrating the technological and economic primacy of the builders' empire.

Construction

A construction ship is required to build the first stage (construction site) of any megastructure. If it has multiple stages, the following stages do not require a construction ship. All megastructures have a different texture depending on the empire that built or repaired them.

Requirements

All megastructures except for Gateways have a DLC prerequisite:

• Ring worlds, Dyson Spheres, Science Nexus, and Sentry Arrays require the  乌托邦（Utopia） DLC
• Matter Decompressors, Mega Art Installations, Strategic Coordination Centers, and Interstellar Assemblies requires the  寰宇企业（Megacorp） DLC
• Mega Shipyards require the  纵横捭阖（Federations） DLC
• Habitats require the  乌托邦（Utopia） DLC unless you're using the  虚空居者（Void Dwellers） origin from the  纵横捭阖（Federations） DLC

With the relevant DLC enabled, each type of megastructure first requires researching its corresponding technology. Except for habitats, all of these technologies have  巨型结构工程（Mega-Engineering） as a prerequisite. Additionally, the  星河奇迹（Galactic Wonders） ascension perk is required to unlock the technologies for Ring worlds, Dyson Spheres, and Matter Decompressors as research options.

Each megastructure also has placement and solar system related requirements. Those are listed in the relevant subsections below.

Megastructure	DLC	Field	Technology	Other requirements0
Habitat	乌托邦（Utopia）	宇航技术（Voidcraft） 3	轨道居住站（Orbital Habitats）

Construction speed bonuses

A few bonuses affect megastructure construction speed. These are highly desirable considering the great time requirements of such projects:

• Master Builders ascension perk increases the build speed by +50%
• Living Metal Mega-Construction edict increases the build speed by +50%
• Architectural Renaissance unity ambition also increases the build speed by +50%
• Using the Isolated Contingency Core relic greatly increases the build speed by +300% for 10 years

Gateways

Real scale of a Gateway

While exploring the galaxy, empires can find abandoned gateways that were once part of a massive, galaxy-spanning network. The number of abandoned gateways can be scaled by galaxy settings. Owning a system with an inactive Gateway drastically increases the chance for the  星门激活（Gateway Activation） technology to appear, which is required to reactivate them.

Reactivation of an abandoned gateway takes 2 years and costs 6000  能量币（Energy Credits） and 2500  合金（Alloys）. When a Gateway is reactivated for the first time in the galaxy, another random Gateway will also reactivate along with it.

Empires can build their own Gateways by researching the  星门建造（Gateway Construction） technology, which requires the Empire to have encountered any pre-existing Gateways, so if Gateways were disabled during galaxy creation, it is impossible to build any new ones.

Each system can only have one Gateway. They can be constructed even in a system with an L-Gate or a wormhole. The construction site must be built outside the system gravity well and is built in 3 years and costs 75  影响力（Influence） and 2500  合金（Alloys）. Upgrading it into a fully functional Gateway takes 3 years and costs 6000  能量币（Energy Credits） and 2500  合金（Alloys）.

Gateways can travel to any other gateway, so long as the empire that owns the gateway has its borders open and is not at war with the traveling fleet's empire. Due to the unique system of the L-Gate, you can jump through one to the L-Cluster, then onto another L-gate so long as its borders are open, or you are at war. Regular empires cannot close their borders to Fallen Empires, therefore regular empires' Gateways can always be accessed by the Fallen Empires, except while at war with them. Claims can be extended through gateways, however only if the borders are open on the side that's getting claimed. Sectors don't extend through gateways.

Gateways are able to greatly enhance and simplify trade routes.

Gateways can't be deactivated or destroyed once they are fully activated or constructed.

Habitats

Plantoid size 4 habitat

Artificial planets in all but name, habitats have 70% Base Habitability for all species regardless of climate preference and can be built orbiting planets. Habitats have a unique set of Districts distinct from normal planetary ones. Habitats have up to 4 district types depending on the owner's government, with a fifth type available if the habitat is built above a planet with certain kinds of resource deposits. Its appearance depends on the builders' ship graphics. They still require colonization but the colony develops 3 times faster on a habitat.

Habitats can be researched and built by any empire if the  乌托邦（Utopia） DLC is installed. Otherwise, habitat construction is only available to empires with the  虚空居者（Void Dwellers） origin, which requires the  纵横捭阖（Federations） DLC. If the  启示录（Apocalypse） DLC is installed, empires created by the Horde breaking up start with the technology to construct habitats even if neither of the required DLCs is installed. These habitats can be captured by other empires.

Habitats can be destroyed by a Colossus as well as by Crisis factions and cannot be rebuilt once destroyed.

Habitat construction

Habitats can be built by a construction ship around any planet without an anomaly. Unlike other megastructures, habitats do not require a construction site and are finished in one go by the construction ship. Habitats start from size 4, which means they can hold up to 4 districts. They can be upgraded via  决议（Decisions）s once all district slots are filled, and go up to size 8.

Placement rules

• Planet must be surveyed
• Planet can't have an anomaly
• Must be a full planet, not a moon or asteroid

Additional placement rules for AI empires

• Planet must have a resource deposit
• System must have an upgraded starbase
• System can't already have an uncolonized habitat

Building a habitat above a planet with a resource deposit leaves you unable to exploit its resource, destroying your mining or research station if one was present. In exchange, the habitat gains a district type and/or planetary feature depending on the type of resource deposit.

Orbital deposit effects

Deposit type	Added district type	Added habitat feature
能量币（Energy Credits）	Reactor District	None
矿物（Minerals）	Astro-Mining Bay

Multi-stage megastructures

 请帮助核对或更新这个段落，最近核对为3.3版本。

Multi-stage megastructures are constructed in multiple stages that require the technology of the same name before they can be constructed. Empires lacking the technology can make use of a multi-stage megastructure they conquered from another Empire, but they cannot upgrade it before they research the technology.

Multi-stage megastructures start with a construction site that provides no benefit. However, each subsequent construction phase will bring increasing bonuses, culminating with the end of the megastructure construction.

Habitats and gateways can be built in the same system as multi-stage megastructures.

It is only possible to build, upgrade, or restore one multi-stage megastructures at a time. The limit can be increased by +1 for each of the following:

• Master Builders ascension perk
• Architectural Renaissance ambition edict
• Level 5 Research Cooperative president

A system can also only host one multi-stage megastructures.

Apart from the Ring World, each multi-stage megastructure can only be built once per Empire, and cannot be rebuilt if the existing one is lost control of, except for the Ring World. However, multi-stage megastructures obtained through conquest, as well as ruined ones that were found in the galaxy and then restored, do not count against the limit. A conquered incomplete megastructure can still be upgraded.

Ring Worlds can have their habitable segments overrun by a Colossus as well as Crisis factions and cannot be repaired again. All megastructures with the exception of Gateways are destroyed by Star Eater firing upon the system's star and become unrepairable.

Ruined megastructures

Ruined Dyson Sphere

A ruined version of a multi-stage megastructure can be found while exploring the galaxy, with larger galaxies having a chance to spawn more ruined megastructures. Repairing them only requires the  巨型结构工程（Mega-Engineering） technology. If not yet researched, owning a system with a ruined megastructure also grants a ×20 weight for  巨型结构工程（Mega-Engineering） to appear as a researchable technology.

While they upgrade from their broken to a fully functional state in one step, they do not count for any achievements. However, they do not count against any build limit for that particular megastructure, either.

Ruined Megastructure	（）	合金（Alloys）	System notes
Dyson Sphere	7200	20000

Conquerable Ringworlds

Up to 8 ringworlds can spawn naturally in a game in various states. Damaged segments can be repaired with the  巨型结构工程（Mega-Engineering） technology for the same cost as finishing a new segment.

• 1 in the Sanctuary system. All 4 habitable sections are intact and each contains one pre-FTL civilization, none advanced beyond Steam Age. The system was abandoned by an Enigmatic Observer Fallen Empire but contains automated defense platforms totaling over 50k fleet power.
• 1 in the Cybrex Alpha system. It requires completing the Cybrex precursor event chain. The ringworld is completely ruined and requires repairs on each section.
• 1 in the Cybrex Beta system. It will only be revealed if the Contingency sterilizes 20% of the galaxy. A short time after the Contingency is defeated, the Cybrex will leave the galaxy, leaving the ringworld free for the taking.
• 1 in a random empty system if  乌托邦（Utopia） DLC is activated. It is completely ruined and each section requires repairing. If the  遥远繁星故事包（Distant Stars Story Pack） DLC is activated as well the system has a 50% chance to contain a unique anomaly.
• 3 in the systems of the Ancient Caretakers if  智械黎明故事包（Synthetic Dawn Story Pack） DLC is activated. The ringworld in the home system has 3 intact and one ruined section while the other two ringworlds are completely ruined and require each section to be repaired separately. If the Contingency appears and the Ancient Caretakers awaken to defend the galaxy, they will also disappear like the Cybrex once the Contingency is defeated, leaving their systems free for the taking.
• Each empire with the  破碎之环（Shattered Ring） origin starts in a ringworld system with an intact segment and two damaged ones. By default only one empire with the origin can be generated but force-spawning will ignore the limit.

Aetherophasic Engine

The Aetherophasic Engine is a megastructure that will appear in the capital system of every empire that reaches the final crisis level. Each stage of the megastructure requires gargantuan amounts of  暗物质（Dark Matter） as well as 10 years to upgrade. If the system is conquered by another empire the megastructure is ruined and can be repaired if the original empire reclaims it.
