How CoD: Warzone Season 4 Could Shake Things Up There's little known about future seasons of Warzone, but some leaks and teases offer a glimpse at what might come to Call of Duty's battle royale. Call of Duty's Season 3 has been one of the best seasons of content since the integration of Black Ops Cold War. A lackluster Season 2 is in the rearview, and players are currently racking up kills as Rambo and John McClane in the '80s Action Heroes event. However, as we look to what could come in Season 4 and beyond, we can see there are still some interesting things potentially on the horizon for Warzone.
