- Dark Events are randomly generated actions of the aliens - just as in the core version of XCOM 2. Their goal is to diminish player's efficiency and improve that of the aliens, or just end the game for the player. Every month, along with the provisions from the Council, the player will also receive a report on possible alien activities - the Dark Events - that will activate during the following weeks.
- In the War of the Chosen expansion, the player can also control these events and either prevent them or mitigate the effects of those he hadn't managed to prevent. One particular type of missions, the Guerilla Ops, are focused precisely on this - finishing such missions will let you to discard one Dark Event. You will be regularly informed about such missions, since they're one of the most important activities in the game.
- Every Guerilla Ops mission should be your absolute priority, demanding immediate attention - otherwise you risk the aftermath of Dark Events spinning out of control, which can be very damaging for your whole performance. Among them are also mission that allow you to impair the progress of the AVATAR program. The table below contains all Dark Events available in the game, along with their effects on the game.
