Activision has announced Call of Duty: Infinite Warfare's fourth and final DLC pack, Retribution, is coming first to PlayStation 4 on September 12. The crazed director, Willard Wyler, has trapped the 4 protagonists inside an all-new horror film, and players must battle the undead to escape Willard Wyler once and for all. Retribution's 4 new multiplayer maps are Heartland, a simulation of small town America akin to the Call of Duty: Ghosts map Warhawk; Carnage, a post-apocalyptic race track along the California coast; Depot 22, a watering hole at the end of civilization with a moving train; and Altitude, a sky-high shopping mall located on the edges of the universe. The Retribution DLC pack will be available for $15 or as part of Infinite Warfare's $50 season pass. A release date for Retribution on other platforms will be announced at a later date.
