Call Of Duty: Warzone's Season 4 mid-season update has landed, and let me tell you, there's a lot to digest. Namely, there's a new objective-based game mode where you escort trucks, and an absolute tonne of weapon balance tweaks. I'm talking about a vast list of guns that have been nerfed or buffed or in-between. The meta hasn't just been shaken up here, it's been flung out of the window.
