There is no doubt that Halo It has been a rival to beat as far as FPS is concerned, especially if we refer to the multiplayer plot. In addition, its setting and in an environment related to science fiction, made the saga something unique that attracted thousands of players since its launch.
Given their unquestionable success, from Infinity Ward they decided that, after the launch of Call of Duty 2, the time had come to get to work on a «Halo killer», a science fiction FPS that will not only rival the Microsoft game, but will surpass the acclaimed title in all sections, including, of course, the number of players.

Of course, this time they would focus on a more contemporary era leaving World War II behind, a decision with which they would finally achieve their goal: Call of Duty 4: Modern Warfare managed to beat Halo 3 in sales, convincing, somehow, in that "Halo killer" they were looking for.
In any case, Halo Infinite is preparing to recover his throne. You know: Spartans never die, they just disappear in combat.
