The Call Of Duty Black Ops IIII multiplayer beta has been held on all platforms, and Treyarch has now gathered enough feedback to detail some of the changes that will make their way into the final game.

For starters, all those who took part in the beta and reached level 34 will receive a permanent unlock token. The developer also outlined changes to Fog of War and Minimap Awareness, Tac-Deploy and Spawning and more.
