Ghost War, the PvP mode for Ghost Recon: Wildlands, finally has a release date. It's launching on October 10, Ubisoft announced today. The 4v4 mode comes to the shooter through a free update on all platforms. Ubisoft previously tested Ghost War in a beta.

Matches play out as best-of-three, with 10-minute rounds. There are eight maps and 12 classes at launch, and Ubisoft has said it will have "regular updates and new content" after launch. This will include more classes, maps, and modes.
