Good news for fans of the classic CoD BR, Warzone 1 is still playable under the new guise of 'Warzone Caldera.' Warzone 1 was temporarily offline when the sequel first arrived, but around a week later the servers came back and the rebrand as Warzone Caldera was complete.

It can only be played on Xbox X/S. I have had the game, for my Xbox one, sinces it's release and have been playing warzone and multiplayer perfectly fine up untill now. The latest update seems to have "optimized" the game to be only playable on Xbox X/S.
