Yesterday, we reported that a big Call of Duty Black Ops 4 update would be coming this week to introduce some tweaks and fixes to the game. Treyarch kept its word sooner than most expected and released the new update a few hours ago.

Among the major improvements introduced by the new update are some stability improvements for the PC version of the game. Featured playlist tiles for Multiplayer and Blackout have been changed as well, with a new 100-Players Duos playlist and an 88-Player Quads playlist, which should fix some of the issues that have been present at launch.
