编辑“危机”

{{Version|3.3}}
'''危机'''（crisis，也通称“天灾”）是一个威胁整个银河系和其中所有生命的事件。有两种类型的危机：一种由外部实体造成的危机出现在末期事件起始年之后，以及另一种由玩家和电脑帝国（除了[[失落帝国]]）造成。

Each time a crisis conquers a planet it causes diplomatic Threat with all empires, making them more likely to cooperate against the crisis. Fallen Empires will send their fleets against a Crisis if it approaches their borders and may even awaken to help fight it.

{{iconify|Defender of the Galaxy}}飞升天赋对危机舰队获得 {{green|+50%}} {{iconify|damage}}加成，making it very useful at turning the tide if more conventional means are ineffective.

== 终末危机 ==
{{SVersion|3.3}}
终末危机（Endgame crises） have a chance to trigger every 5 years once 50 years have passed since the end-game year. If any of the following conditions are met, the crisis can instead happen as soon as the end-game year is reached:

* 没有失落或觉醒帝国
* 没有 [[失落帝国#天堂之战|天堂之战]]
* 有 [[失落帝国#天堂之战|天堂之战]]，但是它开始于 15 年以前或者已经结束

如果以上无一为真，但是任何普通帝国有 {{icon|Jump Drive tech|21px}} [[超光速#跃迁引擎|跃迁引擎]]或 {{iconify|Psi Jump Drives|21px}}科技，或者 {{icon|resolutions}} {{ruby|异次元体实验方法|Extradimensional Experimentation}}议案已通过，那么危机仍能在到达末期事件起始年后出现，不过只有破界者有机会在其他条件符合时提前出现。只有一场终末危机能发生。 

每一个危机有其自己的基础权重，其中虫群天灾有基础权重 10，异次元体入侵者 8，肃正协议 10，以及没有危机 120。对于所有危机，权重将按下列方式增长：
* 2x 在末期事件起始 35 年以后
* 2x 在末期事件起始 50 年以后
* 3x 在末期事件起始 70 年以后
* 3x 在末期事件起始 85 年以后
* 4x 在末期事件起始 100 年以后
* 2x 没有或者不能有 [[失落帝国#天堂之战|天堂之战]]

If the ''Crisis Type'' game setting has been set to a specific crisis then that crisis alone can appear, with a 20% chance to spawn every 5 years. The chance is increased by the aforementioned modifiers.

Endgame crises have a situation log entry that keeps count of the casualties on both sides and shows how close the crisis is to being defeated. During an endgame crisis an audio cue that will play in the background and grow more pronounced the more systems are controlled by the crisis.

=== 虫群天灾 ===
[[File:Alien_Swarm.png|thumb|150px|虫群天灾]]
虫群天灾危机（The Prethoryn Scourge Crisis）开始于一个关于银河系外正在逼近的亚空间回声的通知。立即添加情报日志通知，名为“{{ruby|即将到来的风暴|Coming Storm}}”。

On a MTTH (Mean Time To Happen) of 50 years, they will be close enough to get the general direction of the swarm. A system at the edge of the galaxy will be marked as the center of the Invasion. The system cannot be within or near a Fallen or Awakened Empire. It will not be an owned system either unless every rim system is claimed. 最近的 5 个恒星系被标记给先锋舰队。120 个月之后，将受到来自虫群的传送。

30 个月之后 12 支舰队的先锋就会到达。先锋之后 200–600 天，主力入侵舰队将到达中心星系。在每一个先锋恒星系将生成 3 Star Brood 和 3 {{ruby|运输虫|Transports}}舰队。此时虫群天灾出现在通讯记录但不能与之交流。如果一个帝国的主要物种有 {{iconify|Hive Mind (trait)}}或者 {{iconify|Psionic}}特质，它就能与危机交流，但是外交行动仍然不可能。如果 {{iconify|Galactic Community}}已经建立，可以用与虫群天灾战斗的星系优先事项。

虫群天灾使用下列机制：
* 普雷索林物种自身是不朽的，所以它们的{{ruby|格式塔模型|gestalt pattern}}舰队司令永远不会死于年老。
* The Swarm gets fleets at regular intervals on any system with a spaceport.
** (monthly) If they have no planet and army they get a fleet of 20 armies
** (yearly) If their count of 感染虫 is under 4, they get a fleet of 5 感染虫
** (yearly) If their count of 感染虫 is under 4 but they still have at least 10 ships total, they get a fleet of 3 工虫
* Each fleet will take systems in a way similar to Total Wars.
* Prethoryn 工虫 will build starbases to expand their territory into unclaimed systems. Their starbases are as strong as citadels and modified by the Crisis Difficulty setting.
* The 虫群天灾 use infestors as colony ships. They will land on uncolonized habitable planets and when the colony development process is complete the planet is turned into an infested world. As with regular colony development any orbital bombardment will instantly interrupt the process.
* Prethoryn 运输虫 will invade inhabited planets using ground armies in order to occupy it and purge the Pops. During this phase the planet can be recaptured with ground armies. Once all Pops have been purged the planets will be turned into an {{iconify|infested world pc}}.
* 孵化行星不能被入侵。为了摆脱感染，孵化星球必须被轰炸，直到 {{iconify|Devastation}}达到 100，在那时它将变成一个 {{iconify|barren world}}，能被环境改造。
* If the Scourge overruns a ring world segment it will destroy it. Ring world segments destroyed by the swarm cannot be rebuilt. Overrun habitats are destroyed entirely and are likewise impossible to rebuild.

当虫群天灾被击败，每个帝国将获得 {{green|+20}} {{iconify|Happiness}}持续 10 年和 700-4000 {{iconify|Unity}}。

'''Audio Cue''': As the 虫群天灾 infests more of the galaxy soft chewing sounds will start to be heard in the background.

==== 索林原虫舰队 ====
先锋舰队包括 30 {{ruby|幼虫|Swarmlings}}，由一名带有 Void Swimmer 特质的 {{iconify|admiral}}率领。Star Brood 舰队包括 1 {{ruby|虫后|Queen}}、8 {{ruby|育母|Brood Mothers}}、10 {{ruby|战士|Warriors}}和 35 {{ruby|幼虫|Swarmlings}}，由一名有 25% 几率带有独特的 {{iconify|Hive Affinity}}特质的 {{iconify|admiral}}率领。每 2 年，如果虫群天灾有低于 2000 舰船和至少 1 个孵化行星，它将得到 2 Star Brood 舰队，在 20% 银河领土覆盖率得到第三支舰队，在 40% 领土覆盖率得到第四支舰队。它们也可以从这个增援得到{{ruby|工虫|Constructors}}和{{ruby|感染虫|Infestors}}。

索林舰船有天然装甲，尽管没有使用装甲组件。它们的武器数据由危机强度设置决定。{{ruby|天灾导弹|Scourge Missiles}}和{{ruby|虫群舰载机|Swarm Strikers}}能被逆向工程。

虫群天灾使用独特的 {{iconify|Prethoryn Army}}入侵行星。每一个{{ruby|运输虫|transport}}舰队包括 20 陆军部队而且没有 {{iconify|general}}。索林原虫部队有 400 生命值，每天造成 3-6 伤害和 6-12 士气伤害。它们造成 100% 连带伤害。 

==== 哨兵组织 ====
[[File:Sentinels.png|thumb|哨兵舰队]]
如果虫群天灾覆盖至少 20% 的银河系，哨兵组织（Sentinel Order）将生成。如果一个失落或觉醒帝国存在，它们将生成在其边境旁边，否则它将生成在一个随机帝国的边境旁边。A new black hole system will be spawned for them and they have Fallen Empire level tech although their fleets will lack strength from repeatable technologies. Every few years the Sentinels will create a fleet as long as they have below 200 ships. Sentinel fleets use the ship appearance of all species archetypes except DLC ones and use top-tier components. Their initial fleet also includes a Fallen Empire titan. Sentinel admirals have the {{iconify|Sentinel Training}} trait, giving them {{green|+20%}} damage against the 虫群天灾.

如果虫群天灾覆盖至少 50% 的银河系，哨兵将在虫群解剖学上取得突破，给予每个帝国 {{green|+20%}} 伤害对抗虫群天灾。

Every few years, as long as the Sentinels have more than 30 ships they will offer a one time donation of ships to an empire that destroyed at least 7 Prethoryn fleets and did not attack the Sentinels. Those fleets do not use {{iconify|Naval Capacity}} and cannot be upgraded. Each fleets consist of the following:

哨兵不会扩张。在虫群天灾已被击败几周之后，他们的{{ruby|大团长|Grand Master}}将解散哨兵。

==== 俘获虫后 ====
有两只虫后能被俘获。第一只是 {{iconify|Prethoryn Brood-Queen|21px}}遗珍，which can be obtained by one of the empires in the galaxy after winning a random space battle against Prethoryn fleets. The second is an incapacitated queen that can appear in a random system inside the Prethoryn Space, if the 虫群天灾 is not defeated within a number of decades. A special project will become available there to every empire to tame the queen and the first empire that completes it will gain the domesticated queen as a fleet led by an unchangeable level 8 Fleet Consciousness admiral. Roughly every two months the queen has a 33% chance to add a Warrior to the fleet and a 66% chance to add a Swarmling to the fleet, until the fleet has 30 ships. In addition roughly 100 years later, if the queen is still alive and the main species is {{iconify|Psionic}}, the queen will reveal that the galaxy the Prethoryn species came from has been extinguished or eclipsed by something and the empire will gain 1000-5000 monthly {{iconify|Physics}}.

==== 野生索林原虫 ====
在虫群天灾已被击败 15 年以后，每年有 10% 几率在一个有之前的孵化行星的恒星系出现一个野生索林原虫恒星基地和 3 支野生索林原虫舰队。它们不会扩张但可能漫游到周围的恒星系并且与其它野生索林原虫虫群战斗。漫游舰队由 56 幼虫组成。

==== 成功击退了普雷索林虫群 ====

Prethoryn Swarm entities are heavily armored, attack enemies with missiles and strike craft, along with some acid bursts. Swarmlings possess Corvette-level evasion.

Since all their weapons either ignore or cause major damage to shields, and work equally well against armor and hull, combat fleets should protect themselves with point defense, armor, and plating.  Use energy weapons that deal bonus damage against both armor and hull to attack. Arc Emitters work well too; if you build Arc Emitter battleships, Cloud Lighting is a good support weapon for them.

Empires which lack the means to directly counter the Scourge's fleets should immediately focus on containing its expansion instead. Keeping multiple small fleets of corvettes or destroyers to hunt down their civilian ships and stopping infestations is a viable strategy to limit the spread of the Scourge, as they will send otherwise engaged fleets to try and stop your efforts.

If an important planet falls to a Prethoryn invasion, it will take much longer for them to infest it compared to uninhabited planets, as purging takes much longer than infestation. Infested planets are immediately turned into barren planets once they take enough planet damage. Since the Swarm only can infest habitable worlds, it is possible to starve them by cornering them and launching surgical strikes toward their planets to render them uninhabitable, thus widening the berth between them and any infestable territory. The Prethoryn will pull any fleets from surrounding systems to defend their planets, so fleets targeting Prethoryn planets must be prepared to face multiple swarm fleets if those have not been dealt with already. AI Empires in particular will use such hit-and-run tactics against infested planets. 

Another feasible strategy is to get a Colossus into the area where the Crisis will spawn and breaking all of the planets to starve them, putting your best fleets near the edge of the invasion zone is also helpful, stationing them at the ending for any wormholes leading out of the invasion zone is a must. Additionally, deconstructing certain starbases along the galactic rim once the galaxy has been completely filled up allows you to control where the Swarm will spawn, although you will have to make sure the AI don't try and take those otherwise unclaimed systems.

Prethoryn "Star Brood" fleets are composed of at least one Queen, escorted by Warrior and Brood Mother battleship equivalents, with Spawnling corvettes making up the bulk of the fleet combat strength. A fleet equipped with long-range weapons can expect to destroy a number of Spawnlings before the Prethoryn units are able to return fire, at which point emergency FTL can be used to avoid casualties altogether. By repairing and repeating, this guerrilla tactic can wear down Prethoryn fleets until they are small enough to defeat in a full confrontation.

Salvage should not be forgotten as it unlocks their bio-weaponry, which is most useful against them. Their starbases are equally good sources of technology while being much easier targets.

=== 异次元体入侵者 ===
[[File:Alien_extradimensional_01.png|right|thumb|150px|异次元破界者]]
异次元体入侵者危机（The Extradimensional Invaders Crisis）begins with a note about a massive power surge somewhere in the galaxy (the formal event title is "Galactic Power Surge"). Immediately somewhere in the galaxy a {{ruby|位面传送门|Dimensional Portal}}, a portal starbase and the main Unbidden fleet will emerge. If the system lies within the borders of an empire the starbase is instantly destroyed. If the Galactic Community was formed a Galactic Priority to fight 异次元体入侵者 becomes available. 15 days later a second fleet will emerge. Another 15 days later a third fleet will emerge, contact with the Unbidden will open and the location of the Dimensional Portal will be added to the Situation Log. Fleets will take systems from empires in a way similar to total wars, while constructors will build starbases in unclaimed systems.

The Dimensional Portal cannot be destroyed until all Dimensional Anchors are destroyed. These are located in systems highlighted in the Galaxy Map. The portal will remain guarded by the main Extradimensional fleet. If the portal system is attacked, then the invaders will recall all of their ships to aid in its defense. If the starbase in the portal system is destroyed, all fleets will remain to guard the system until it is rebuilt, halting their expansion. The empire that destroys the last Dimensional Portal will gain the [[File:R unbidden warlock.png|24px]] Extradimensional Warlock Relic as well as a temporary {{iconify|opinion}} bonus from everyone.

如果一支异次元舰队到达一个不设防的行星，它将从轨道上收割生命。当该行星达到 100 {{iconify|devastation}}，它就变成了一个 {{iconify|barren world}}带有 {{iconify|Terraforming Candidate}}修正。{{iconify|Ring world}}区段被它们摧毁后不能重建。Overrun habitats are destroyed entirely and cannot be rebuilt.

异次元体入侵者在传送门生成之后的 55、90、180、265、340、425 和 550 天得到额外的舰队。Afterwards, unless they have more than 2000 ships, they will receive smaller reinforcement fleets through the portal at regular intervals, with the interval being lower if they have more starbases:
* 0 恒星基地：1500 天，±200
* 1 恒星基地：1300 天，±200
* 2 恒星基地：1100 天，200
* 3 恒星基地：900 天，±200
* 4 恒星基地：600 天，±200
* 5 恒星基地：400 天，±200 
* 6 恒星基地：400 天，±200
* 7 恒星基地：300 天，±100
* 8 恒星基地：250 天，±50
* 9 恒星基地：200 天，±50
* 10+ 恒星基地：150 天，±50

It should be noted that unlike the other crises, which provide warning several years in advance, 异次元体入侵者 will arrive instantly and with no indication where the portal will open.

从 [[3.1 版本]]，异次元舰队无视 [[超光速#超光速抑制器|超光速抑制器]]。

破界者、背道者和狂热者舰船使用不同的名称，但是除了颜色完全相同。所有组件都可以进行逆向工程，包括其独特的武器。

Initial fleets consist of 8 battleships, 12 cruisers and 20 escorts led by an admiral which may get the Dimensional Stutter or Ethereal traits.

Reinforcement fleets consist of 5 battleships, 8 cruisers and 15 escorts led by an Admiral which may get the Dimensional Stutter or Ethereal traits.

Portal fleets consist of 20 battleships, 30 cruisers and 45 escorts led by an admiral with the Ethereal trait.

==== 背道者与狂热者 ====
When the Unbidden border covers at least 15% of the galaxy a second extradimensional portal will open, bringing up another faction called the Aberrant. A few years later a third portal bringing a third faction called the Vehement will open. While all three factions will be hostile towards life, they are also hostile towards each other.

The new factions have a far shorter delay for the Initial Fleet spawns (1, 5, 15, 30, 45, 60, 150, 350) in order to bring them on even ground with the Unbidden.

==== 成功击退了异次元体入侵者 ====
Unbidden ships are heavily shielded and have no armor, so using fleets with only kinetic weapons is very effective. In terms of fleet composition, focus on artillery Battleships combined with Titans using the shield dampening aura, as the L and X weapons have more range than any Invaders weaponry. In terms of defense the Invaders solely use energy weapons so a focus on shield modules is ideal.

The player has multiple strategic choices when faced with these Extradimensional Invaders:
* A quick rush after the portal opening might be possible. However, one needs to be able to quickly dispatch the portal guards and initial fleets as they spawn, which requires very powerful fleets.
* Unlike other crises, their initial invasion fleets are much stronger than reinforcements.  If the player can effectively clear their initial fleets, reinforcements shouldn't be a problem since they're much weaker than initial ones.
* Salvage should not be forgotten as it unlocks their unique weapons. The starbases are equally good sources of technology as the fleets while being much easier targets. However, the 物质分解器 weapons are anti-armour and hull, and the extradimensionals use no armor on their ships, so replacing your weaponry with these is generally a bad idea to fight the invaders.
* If extradimensional invaders claimed lots of systems before normal empires can strike back, player should focus on destroying their starbases and construction ships, since starbases will reduce reinforcement interval.

The arrival of the other extradimensionals are a mixed blessing. On one hand, they might appear in the rear of a large empire or alliance, threatening important worlds and thus the defense against the existing Factions. On the other, all extradimensional factions will begin to fight each other, potentially causing major damage to one another. Once engaged in combat there, the enemy fleets will have difficulty defending any of their starbases and even the portal itself making this a crucial opening to strike at such critical targets.

=== 肃正协议 ===
[[File:The_Contingency.png|thumb|肃正协议]]
肃正协议危机（The Contingency Crisis）begins with a signal dubbed the Ghost Signal bouncing across every empire. Every year each empire will be affected by an event, in the following order:
# Every biological empire that uses synthetic pops will lose one synthetic pop and every machine empire will lose a machine pop in one of two special events.
# Every biological empire that uses synthetic pops will lose another synthetic pop mysteriously.
# Every empire will get a notification about galaxy-wide synthetic disappearances.
# Every empire will get a notification about the Ghost Signal growing stronger and how it affects machines and synthetic pops differently.

A year after the final event the Contingency will activate. Every 50 days one of 4 random uninhabitable planets located in systems with Strategic Resources will transform into Sterilization Hub AI world and spawn a defense station, 3 attack fleets, and 3 construction ships and an army fleet. The planets are determined at galaxy generation so reloading a save will not alter the result. If the Galactic Community was formed a Galactic Priority to fight the Contingency becomes available. The hubs can not be invaded and must instead be bombed until they reach 50 {{iconify|Devastation}}, at which point they turn into broken planets with a deposit of {{iconify|Energy}}, {{iconify|Minerals}} and {{iconify|Living Metal}} and may unlock the technology to harvest it. Colossus owners can also use a World Cracker, Global Pacifier or Divine Enforcer on sterilization hubs but the worlds will not gain a deposit that way.

When a planet is captured by the Contingency it immediately starts the process by purging all pops - biological, synthetic and machine alike. If the planet is recaptured the purges will stop and the planet returns to the original owner. If the purge is completed the planet changes control over to the Contingency. 3 {{iconify|Mechanical}} pops called Custodian Bots are spawned but the planets will not reinforce the Contingency. Unlike Sterilization Hubs, purged planets can be captured in ground combat. Unlike other crises the Contingency does not ruin ring world segments or habitats.

在所有灭绝中心被摧毁后，一个新的恒星系将出现在星系尽头。该恒星系包含第五个也是最后一个 {{iconify|AI world}}——Nexus Zero-One——由 1 Final Core 和 4 AI Core 空间站守卫。当 Nexus Zero-One 被摧毁，肃正协议失效，所有其舰船自毁，渗透事件和特殊项目终结并且幽灵信号被移除。摧毁 Nexus Zero-One 的帝国将获得 {{iconify|Isolated Contingency Core}}遗珍（只给人类玩家，不确定这是有意的）。当该行星被摧毁，不创建任何矿藏。

从 [[3.1 版本]]，肃正协议舰队无视 [[超光速#超光速抑制器|超光速抑制器]]。

'''Audio Cue''': As the Contingency sterilizes more of the galaxy a mainframe will start to be heard in the background.

==== 幽灵信号 ====
肃正协议生效之后，幽灵信号（the Ghost Signal）将开始影响每个合成人人口甚至带有{{ruby|智慧战斗电脑|Sapient Combat Computer}}的舰船。It is measured in 5 levels and starts at 5. The Ghost Signal will lose strength each time a Sterilization Hub is destroyed, lessening its effects.

{{expansion|utp|snd}}
Autonomous Ship Intellects used by {{iconify|Gestalt Consciousness}} are immune to the ghost signal.

Synthetically Ascended species are also immune to the Ghost Signal, however any mechanical pops built by these empires that aren't considered part of their main species of synths will be affected.

Machine Intelligence Empires are affected differently as the Contingency attempts to breach their core and take over the central AI. And as such the bulk of processing resources is redirected to the Firewall to prevent that, significantly reducing the efficiency of their drone workers. While a lower penalty per pop, given the demographic nature of these Empires it might be a much bigger penalty. As they are much more heavily affected, Machine Intelligence Empires will get the special project "Blocking the Ghost Signal". The cost is 600 + 100 * Pop count {{iconify|Engineering|24px}}. Finishing it will remove its effects.

==== 合成人的渗透 ====
While the war rages among the stars, organic, machine and syntheticallly-ascended empires might have issues at home as well.

The first infiltration attempt will invariably fail. The second infiltration will happen 120 days afterwards and will make every organic and synthetic empire targetable for infiltration events. It will also grant the Synth Detection project within a year. Completing this project grants the Voight-Kampff [[achievement]] and a large amount of unity. Until completed every year each organic and synthetic empire has a 30% chance to get the Terror Gatekeeper event, which will trigger a damaging infiltration event. Aside from Synth Bombing each event can only happen once. The weights are the following:
* 40% Synth Bombing: On a random planet three worked buildings are ruined and the pops working them killed. The empire will then get {{red|-10%}} {{iconify|Unity}} for 6 years.
* 10% Spaceport Scuttled: A random starbase is destroyed.
* 10% Fear and Suspicion: A random planet gets {{red|-20}} {{iconify|Stability}} for 20 years.
* 10% Ruler Assassination Attempt: 70% chance the ruler escapes and gain some {{iconify|Influence}}, 30% chance the ruler is killed.
* 10% Scientist Exposed as Synth: A scientist leader is killed.
* 10% Admiral Exposed as Synth: An admiral leader is killed.

{{expansion|utp}}
{{iconify|Hive Mind}} and {{iconify|Psionic}} empires cannot be infiltrated. Instead, the first infiltration event will describe how their population cannot be infiltrated and how the Contingency will not try further infiltration on them. Infiltrated empires that take the [[File:ap transcendence.png|21px]] Transcendence ascension perk will also become immune to infiltration. {{iconify|Machine Intelligence}} empires also cannot be infiltrated, and will instead receive the "Blocking the Ghost Signal" project.

==== 警告信号 ====
{{expansion|snd}}
Instead of infiltrations, {{iconify|Machine Intelligence}}s are attacked more directly by the Ghost Signal. They will get a security breach event that will make every machine empire targetable. Until the "Blocking the Ghost Signal" project is completed or the Ghost Signal strength drops below 4 each year every machine empire has a 30% chance to get the Terror Gatekeeper event, which will trigger a damaging subversion event. Aside from Unit Stack Error each event can only happen once. Chances are equal for each event.
* Spaceport Scuttled: A random starbase is destroyed.
* Science Unit Terminated: A scientist leader is terminated.
* Military Unit Terminated: An admiral leader is terminated.
* Power Grid Malfunction: Three Power Plants or Power Hubs and the pops working them are destroyed.
* Contingency Intrusion Averted: Contingency sabotage fails, 无效果.
* Unit Stack Error: Errors are detected in a unit stack, which may be caused by the Ghost Signal. You are given the option to either terminate the units (no pop is actually terminated) or wait. If you choose the latter after 120 it will turn out to be either:
** 65% A false alarm. Nothing happens.
** 35% A true alarm. A random planet gets {{red|+10%}} Devastation and loses 4 Pops.

==== 赛博勒克斯 ====
Originally one of the Precursor empires, the Cybrex will resurface to help fight the Contingency if it sterilizes over 20% of the Galaxy. At the edge of the galaxy the Cybrex Beta ringworld system will spawn. All Empires will be contacted immediately. The Cybrex will construct a new fleet every few years as long as they have below 300 ships. The Cybrex function analogous to the Sentinels of the Swarm Crisis, except they will only donate ships after 100 destroyed fleets and will take them back a month after the crisis ends.

Cybrex ships are identical to the Contingency's save for the color. Each fleet is led by an admiral with the Cybrex Databases trait, giving it +10% Evasion and Fire Rate and +20% Damage to the Contingency.

The Cybrex do not expand. A few weeks after the Contingency was defeated they will depart from the galaxy, leaving Cybrex Beta free for the taking.

==== 上古看护者 ====
{{expansion|snd}}
A few days after the first sterilization hub is revealed if the Ancient Caretakers are present in the galaxy they will awaken and the Contingency will attempt to corrupt their civic. The Ancient Caretakers have a 66% chance of gaining the [[File:Civic final defense protocols.png|24px]] Final Defense Directives civic (Guardians of the Galaxy awakening) and a 33% chance of gaining the [[File:Civic malfunctioning custodian.png|24px]] Corrupted Defense Directives civic and start attacking every other empire (Berserkers). Whether they will awaken as Custodians or Berserkers is rolled at the start of the game so reloading a previous save will not alter the result.

5 years later other Fallen Empire may awaken as a Guardians of the Galaxy as usual, allowing up to 3 Guardian empires against the Crisis.

Once the Contingency is defeated if the Ancient Caretakers awakened as Guardians they will shut down, leaving their ringworlds free for the taking.

Roaming fleets consist of 10 euthanizers and 20 sterilizers led by an Admiral with random skill.

Hub fleets consist of 25 euthanizers and 50 sterilizers led by an Admiral with random skill.

'''Special Weapons:''' The Contingency uses stock weapons, with only one exception - 搜寻者无人机:
* 10 Units per Hangar
* 100 HP, 50 Armor, 50 Shield, 80% Evasion per Unit
* 19-21 Damage with 100% accuracy and no tracking, 20 Range, 8 CD, 100% Shield Penetration, 66% Armor Penetration

Contingency uses Android Assault Army to invade worlds.  Each transport fleet consist of 20 Android Assault Army and do not have a general.

==== 成功击退了肃正协议 ====
肃正协议{{ruby|战体|warforms}}使用大量的护盾和装甲去保护它们相对脆弱的船体，所以穿透性武器（电弧发射器、裂解炮等）可以很好地对付它们。However, due to the lack of effective L sized piercing weaponry, using Battleships or Titans with 50/50 kinetic and energy weaponry works well too. Defensively, attackers should stack as many shields as they can to counter their pure energy weaponry.

The initial Fleet spawned with the hub systems is considerable and planets in the Hub Systems will often have fallen before the first fleet has mobilised. Colonies in the Hub Systems are generally a writeoff until the roaming fleets have been dealt with.

Even if identified beforehand, hubs normally cannot be prevented from awakening. If the planet is destroyed through the World Cracker Colossus, the shattered world will simply reform into the sterilization hub. Military starbases on the star will be abandoned if there are no colonies there, rendering any resources spent moot. If fleets are parked in the system, the Contingency will spawn an armada of much greater power than standard. The only known method of preempting them is to build at least a ringworld frame in the system, although this also eliminates all other planets.

The first order is generally to destroy any roaming fleets (if they attack one's planets). The Contingency fleets already spawned are generally not likely to rush to the aid of a planet or hub. They are more likely to attack another target than defend. 

Destroying the hubs is the ultimate goal. Their hub fleets will always stay with the Hub, making it a hard target together with the AI Core and the starbase. While destroying one of the hubs does reduce the reinforcement intervals, the reduction in spawn cycles running in parallel should be a net advantage.

{{expansion|nem}}
有 {{iconify|Become the Crisis}}飞升天赋的普通帝国也能成为危机。Empires that pick the ascension perk will be able to acquire {{iconify|menace|21px}} and complete expensive crisis special projects to gain various perks. It should be noted that only upon reaching the fifth crisis level is the empire treated as any other crisis: full war with every other empire (the declare crisis resolution). This means that through levels 1-4, the "crisis" empire acts as normal, save for not being able to become the Custodian. Level 5 and only level 5 crisis is the "point of no return", gated by the Special Project to level up, so to speak. This gives the ascension perk far more value for empires who don't want to take the final step, with its various bonuses. The crisis tab is located under the traditions tab.

威慑力通过完成危机目标获得。每一个目标的获得量取决于游戏开局出现的帝国数量。当前威慑力能在危机标签页找到。

Once enough {{iconify|menace|21px}} and special projects are completed the empire will gain a new crisis level, unlocking additional perks. The last crisis level requires the empire to be independent.
