Endgame crises have a chance to trigger every 5 years once 25 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:
There are no Fallen or Awakened Empires
There won't be a War in Heaven
There was a War in Heaven, but it either started over 15 years ago or has finished
If none of the above are true but any regular empire has either the Jump Drives or Psi Jump Drives technologies or the Extradimensional Experimentation resolution is passed, then the crisis can still appear upon reaching the end-game year, but only the Unbidden will have a chance to appear early until one of the other conditions is met. Only one endgame crisis can take place.
Each crisis has its own base weight, with the Prethoryn Scourge having a base weight of 10, the Extradimensional Invaders 8, the Contingency 10, and no crisis 120. For all crises the weight will increase the following way:
2x after 35 endgame years
2x after 50 endgame years
3x after 70 endgame years
3x after 85 endgame years
4x after 100 endgame years
2x if there won't be or can't be any War in Heaven
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.
The Endgame crisis multiplier increases the hull, shield, armour, damage respectively, but not the ship fire rate.
