The live-service lifecycle for Call of Duty: Vanguard and Call of Duty: Warzone is winding down. The fifth and final in-game season is set to debut on August 24, and this will, in all likelihood, mark the last major update before the release of Call of Duty: Modern Warfare 2 and the long-anticipated Call of Duty: Warzone sequel. Developer Sledgehammer Games seems to have cooked up a pretty captivating send-off, as, alongside a host of new maps, modes, and weapons is a selection of four new operators, all of whom hail from previous Call of Duty titles.
