巨型结构

Humanoid Empire constructing a Dyson Sphere

!此wiki中文部分基于3.12!

巨型建筑是在反重力条件下建造的建筑。建造或维修这些非凡的工程杰作既昂贵又耗时，但它们是重要的奇迹，能提供大量收益，显示建造者帝国的技术和经济优势。巨型建筑不能建造在有未调查异常的天体轨道上。

建造

建造任何巨型建筑的第一阶段(基址)都需要一艘工程船。如果巨型建筑有多个阶段，后面的阶段则不需要建造飞船。所有巨型建筑都有不同的纹理，这取决于建造或修复它们的帝国。

建造速度提升

有一些方法可以提升巨型建筑的建造速度。考虑到此类工程需要大量时间，这些方法非常可取：

•  建筑大师（Master Builders） 飞升会可提高 +50%的建造速度
• 活体金属巨构工程法令可提高 +50%的建造速度
• "野望: 建筑复兴"可提高 +50%的建造速度
• 独立的肃正核心遗珍可在启用 10 年内提高 +300% 建造速度

超光速巨型结构

Real scale of a Hyper Relay

超光速巨型建筑只能建造在星系的边缘，允许舰队穿越到相同的巨型建筑，大大方便了银河系的旅行。它们将与另一个帝国的超光速巨型建筑协同工作，除非关闭边境或帝国之间发生战争。超光速巨型建筑可以在任何还没有这种巨型建筑的星系中建造。与其他超大型建筑不同的是，它们也可以在附属国的星系中建造。

星门

在探索银河系时，帝国可能会发现废弃的星门，这些星门曾经是横跨银河系的庞大网络的一部分。废弃星门的数量可以通过galaxy settings来调整。<ref>将废弃星门设置为 0 会阻止星门技术的使用，因为帝国必须发现至少一个星门才能解锁研究。如果设置为 0，繁星门阶起源仍会产生一对废弃星门。

一旦发现废弃星门， 星门激活（Gateway Activation）技术就会一直有机会出现，从而修复废弃星门。修复废弃星门需要花费 2 年时间和   6000 能量币（Energy Credits）、  2500 合金（Alloys）。当银河系中的一个网关首次重新启动时，另一个随机网关也会随之重新启动。

一旦 星门激活（Gateway Activation）技术被研究出来，{ 星门建造（Gateway Construction）技术就会一直有机会出现，从而可以建造新的网关。建造网关需要花费  6000 能量币（Energy Credits）和 Template:红色 合金（Alloys），耗时3年。升级为全功能网关需要 3 年时间，耗费   2500 合金（Alloys） 和   6000 能量币（Energy Credits）}。

只要边界是开放的，目的地不受敌方帝国控制，星门就可以立即前往任何其他网关。星门通常就像系统之间的超空间航道，战争和贸易可以通过网关进行，但星域不能通过星门进行。

L-Gate是一种特殊类型的星门，拥有与普通星门不同的独立网络。L-星门不是从任何星门跳转到任何星门，而是全部跳转到 L-星团的终端出口系统，然后再从终端出口系统跳转到任何其他 L-星门，只要其边界是开放的，或者你们正在交战。L-星门是通过特殊项目打开的，在此之前，需要研究7个L-星门线索和而且无法建造新的 L-星门。

超空间中继器

一旦(unrecognized string “hyper relays” for Template:Icon) Hyper Relays技术被研究出来，就可以建造超级中继器，让飞船跳转到邻近星系的超空间中继器，而不是使用现有的超光速航道，从而避免以亚光速穿越星系。超空间中继器的建造只需一个阶段，耗时一年，花费   25 影响力（Influence）、  500 合金（Alloys）和  100 稀有水晶（Rare Crystals）。超空间中继器链接在星系地图上显示为较粗的超线段。潜在（非活动）链接在星系图上显示为黄色连接。由于边界关闭、战争或中继站被毁，链接可能处于非激活状态。被毁坏的超级中继站可以通过  500 能量币（Energy Credits）、  500 合金（Alloys）和  100 稀有水晶（Rare Crystals）}进行修复，修复时间为6个月。

超级中继器可以根据 法令（Edict）和附属国赋予额外效果。超空间中继器法令要求帝国的首都系统是网络的一部分。包括网道主导、网道迁移、网道娱乐，都需要稀有资源和{iconify|unity}作为维护费。而附属国专业化所带来的好处则要求宗主国的首都与附属国的首都之间存在连接。附属国无法从宗主国的网络效应中获益。

超空间中继器可以在星系视图中建造，并会半随机地放置在星系中。在有wormholes或现有星门的系统中，建议进入星系视图，手动将超级中继器放置在wormholes或星门附近，以方便旅行。不过，超级中继器无法通过wormholes或星门进行连接。

Orbital megastructures

Orbital megastructures can only be constructed in orbit of a planet. Unlike other megastructures, orbital ones do not require a construction site and are finished in a single stage by the construction ship. Each planet can only have one orbital megastructure, which can be further upgraded. Their appearance is dependent on the builder empire's ship set.

Habitats

Plantoid size 4 habitat

Artificial planets in all but name, habitats have a 70%  base 宜居性（Habitability） for all species and can be built above planets. Habitats have a unique set of districts distinct from normal planetary ones. Up to 4 district types are available on all habitats, with a fifth one being available if the habitat is built above a planet with a resource deposit. Building a habitat above such a planet leaves you unable to exploit its resource directly, destroying any mining or research station if one was present; however,  战略资源（Strategic Resources） are added to the habitat as a special deposit, so they are not lost. Habitats still require colonization, but the colony develops twice as fast on a habitat. Habitats start at (unrecognized string “size” for Template:Icon) size 4, which means they can hold up to 4 districts. They can be upgraded twice via decisions once all district slots are filled, up to size 8.

Habitats can be researched and built by any empire if the  乌托邦（Utopia） DLC is enabled. Otherwise, they are only available to empires with the  虚空居者（Void Dwellers） origin, which requires the  纵横捭阖（Federations） DLC.

(unrecognized string “size” for Template:Icon) Size	Cost	Time	Housing buildings	Required technology
4	150 1500	1800 days	格式塔意识（Gestalt Consciousness） only	轨道居住站（Orbital Habitats）
6	1000	720 days		居住站扩建（Habitat Expansion）
8	1500	1440 days		高级太空居住站（Advanced Space Habitation）

The  太空子民（Voidborne） ascension perk adds   +20% 宜居性（Habitability） to habitats (resulting in 90% habitability without other modifiers) and unlocks   +2 建筑槽位（Building Slots）.

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

If the  启示录（Apocalypse） DLC is enabled, empires created by the Horde breaking up start with the technology to construct habitats even if neither of the required DLCs is enabled. These habitats can be captured by other empires.

Orbital Rings

Half megastructure and half starbase, Orbital Rings require the planet to be colonized before they can be built. They protect the planet from being invaded and can do everything a starbase can.

In addition to the regular starbase buildings, Orbital Rings can construct a set of buildings that improve the planet's output. All of them take one year to build.

Multi-stage megastructures

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 which 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.

Only one multi-stage megastructure may be built in each system. Multi-stage megastructures must be built either over an uninhabitable planet or the central star of the system (with the exception of the Quantum Catapult). There must not be an anomaly present on the planet or star, but an anomaly on another planet or star in the system will not block construction (even for the Ring World).

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

•  建筑大师（Master Builders） ascension perk
• Architectural Renaissance ambition edict
•  Level 5 研究合作组织（Research Cooperative） president

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 or destroyed. 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 this limit. A conquered incomplete megastructure can still be upgraded as long as the new owner has the requisite technology.

Ring Worlds can have their habitable segments overrun by a Colossus as well as Crisis factions and cannot be repaired again. All multi-stage megastructures can be permanently ruined if the system is destroyed by a Star Eater.

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 Mega-Engineering to appear.

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
Science Nexus	4800	15000
Sentry Array	4800	15000	Contains a Tomb World

Empires with the File:Origins slingshot to the stars.png Slingshot to the Stars origin can repair the special Quantum Catapult without the  巨型结构工程（Mega-Engineering） technology.

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 the  乌托邦（Utopia） DLC is enabled. It is completely ruined and each section requires repairing. If the  遥远繁星故事包（Distant Stars Story Pack） DLC is enabled as well, the system has a 50% chance to contain a unique anomaly.
• 3 in the systems of the Ancient Caretakers if the  智械黎明故事包（Synthetic Dawn Story Pack） DLC is enabled. 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.
