The developer of the game answered the curious question.
Call of Duty: Black Ops 4, officially announced in the past days, has been able to satisfy the players in general, collecting some of the players’ negative criticisms. The Treyarch developers who removed the story from the new game announced that they would add zombie mode and Battle Royale mode to the game instead. Later, it was wondered what kind of camera angle would be used by this Battle Royale mode, which would be a rival to PUBG and Fortnite. The Battle Royale mode, which is already famous for the TPS camera lineups, is based on the announcement that the Call of Duty: Black Ops 4 will be a FPS.
Call of Duty: Battle Royale mod FPS developed for Black Ops 4
Already in the new Call of Duty game players did not expect a game TPS. But this question was also answered. In view of this information from David Vonderhaar, one of the developers of the game, we can say that Call of Duty: Black Ops 4 will offer a much different game than PUBG and Fortnite. Although it is FPS mode in PUBG, we can not define PUBG as a Battle Royale game that offers pure FPS experience, since game play mechanics are set according to TPS mode.
