The official Call of Duty Black Ops Cold War multiplayer reveal is set for September 9th, but a leaked gameplay video from the Alpha appeared this morning. We've embedded it from YouTube, though it is likely it will be deleted as soon as Activision spots it, so we're also dropping this Reddit link.

We don't know much about the multiplayer of Black Ops Cold War, other than it will support cross-play functionality just like Modern Warfare. It will also be linked with the free-to-play Call of Duty Battle Royale, Warzone, sharing progression such as inventory items that can be used in both games.
