New CALL OF DUTY: MODERN WARFARE Update All But Confirms CALL OF DUTY: WARZONE Battle Royale

Call of Duty: Modern Warfare's second season of post-launch content only kicked off the other day — find out more about that here. Earlier today, heaps of evidence emerged suggesting that a new Call of Duty battle royale is about to rear its head.

A leaked image surfaced online and kicked it all off — featuring the name "Call of Duty: Warzone" — and a reputable insider suggested that it's coming very soon — more on that here. Well, now it seems all but confirmed that Call of Duty: Warzone is legitimate and on the way as evidence has been discovered within Call of Duty: Modern Warfare itself.

The newest update to the latest instalment in the long-running first-person shooter franchise has introduced a new option to the main menu. As well as Campaign, Multiplayer, Co-Op, and Store; there's now a section that simply says "Classified," and it's located rather prominently.

If that isn't enough for you; since the latest update, multiple players have found themselves accidentally placed into a menu which is very clearly meant for the battle royale mode — it even says "Warzone," at the top of the screen. However, the options are all locked — one of them being a Training Mode.
