Dark Events are a game mechanic in XCOM 2 that represents the aliens' progress toward completion of their Avatar Project or counter-insurgency activities efforts aimed at disrupting XCOM's activities.

At any given time, the aliens can be working towards up to four Dark Events, each with an individual timer. Which ones are currently active can be viewed on the global map under the Dark Events button at the top, along with estimated timers until next Avatar facility construction and next Resistance Strike crackdown.

Dark Events can be countered by Guerilla Ops, of which typically one will be offered per month. Choosing which ones you will have to let go and which ones you can't stand seeing fire can be just as important as the reward offered for each individual Guerilla Op.

Upcoming Dark Events[]

After each monthly debriefing, the player is informed about Dark Events currently being prepared. If an event has successfully been triggered, it will be replaced with a Hidden Event in the upcoming month. The player is given a chance to invest 20-30 Intel to reveal what type of event is coming up, this cost can also be paid at any point until the event is set in motion.

These Intel costs are subject to any active Intel-cost penalties. If the player opted not to reveal the nature of any Hidden Events, it will not be until the next month that the opportunity to do so returns. In addition, each monthly report only allows for one Hidden Event to be revealed.
