ADVENT Blacksite Assault is a key plot mission in XCOM 2.
Background[]
The Spokesman contacts the Commander and informs them that increasing numbers of missing civilians are disappearing around the globe, and he suspects they are being taken to a nearby ADVENT Blacksite whose exact location is unknown. The Spokesman tells XCOM to establish contact with resistance cells, take charge of resistance operations, and shut down the Blacksite. The player must research Resistance Communications, fly to the Blacksite region, and make contact with the region to reveal the Blacksite's location. XCOM can then send a squad to investigate the Blacksite.
Mission[]
The deployed squad starts in concealment. The map contains a facility and a predefined EVAC zone. Fighting their way through the enemies patrolling the area, the soldiers discover piles of containers containing humans preserved in stasis, confirming ADVENT has been behind the disappearances.
Within the facility, they discover humans being processed or refined. They take a vial containing a sample from the facility. After they take the vial, an ADVENT dropship deploys more forces on the map. The mission is successfully completed when all surviving XCOM soldiers reach the EVAC zone and evacuate.
Outcome[]
The rewards for this mission are:
- 125 Supplies (all difficulties)
- Reduced Avatar Project progress by 1 (2 on Legend)
- Blacksite Vial
Completing this mission triggers a cutscene where the Spokesman reveals his discovery that the Blacksite is part of a clandestine ADVENT operation called the Avatar Project. ADVENT is diverting resources and personnel to covert facilities worldwide. The Spokesman tells the Commander to disrupt the Avatar Project's progress, uncover the truth of its purpose, locate its source and destroy it.
The Doom Counter is activated by completion of this mission.
Once the Shadow Chamber is built, the Blacksite Vial research project can be completed, making the ADVENT Forge Facility Assault mission available.
