PT, for the uninitiated, is the 'Playable Teaser' for the cancled Silent Hills project that Hideo Kojima was working on.
That being said, one of the recent claims RalphsValve has made about Call of Duty: Modern Warfare 2 is that the game will have a PT-inspired game mode to replace Spec Ops. RalphsValve has not provided any evidence to back up their claims, and so whatever they say about Call of Duty: Modern Warfare 2 can only be taken as an unsubstantiated rumor for now. Like with any other supposed 'leak,' it's always better if fans take the information with a massive grain of salt. Twitter user RalphsValve tweets primarliy about Call of Duty news, and they have been tweeting 'leaks' about Call of Duty: Modern Warfare 2. Rumors have started spreading about what Call of Duty: Modern Warfare 2 will entail, and one of the more recent ones is rather surprising.
Reportedly a sequel to 2019's Call of Duty: Modern Warfare, the rumored Call of Duty: Modern Warfare 2 is supposedly well into development at Infinity Ward. Call of Duty: Vanguard isn't even out yet, and rumors are already swirling about the 2022 Call of Duty game.
