Call of Duty: Modern Warfare 2 did away with the new reveal style established by Call of Duty: Black Ops Cold War and Call of Duty: Vanguard. Not only was there a simple trailer release instead of a special event within Warzone, but the game was unveiled roughly five months before release. This is a far cry from Black Ops Cold War and Vanguard, which were unveiled to the public just a few months before actually releasing.
