Call of Duty: Modern Warfare Beta on PS4 gave players an early look at the 2019 reboot that redefined the franchise with its gritty, realistic tone and the introduction of the "Gunsmith" system. Participants were able to test out new modes like "Gunfight" and the massive "Ground War," providing critical feedback on weapon balance and map flow. This era marked the birth of the modern Warzone experience and the return of iconic characters like Captain Price in a brand-new timeline. Today, the Beta serves as a milestone for when Call of Duty shifted toward a more tactical, immersive engine that would carry the series for years to come.
