Last week, Ubisoft teased a Ghost Recon Wildlands crossover with Rainbow Six Siege coming with the launch of Special Operation 2, the second of four free updates planned for Wildlands' Year 2. Today it revealed which Rainbow Six operators will be joining the party in Bolivia: The Navy SEAL Valkyrie, GIGN's Twitch, and Caveira of BOPE, who's gone off the grid and on a homicidal rampage. 

Valkyrie, you see, is an old friend of Karen Bowman, the CIA shot-caller working with Ghost Recon in its war against the Santa Blanca Cartel. So when Caveira goes missing in Bolivia, she enlists their aid to join her and Twitch in the search. There is a narrative to untangle—"The Ghosts will follow a trail of clues, to learn more about why Caveira is in Bolivia, and also about her troubled past"—but the real attraction for most players will be the practical rewards: Finishing the two-part Operation Archangel PvE mission before August 14 will get you Caveira's gloves, which enable her "iconic" CQC move and automatically unlocks the positions of all enemies in the area when equipped.
