Call of Duty: Infinite Warfare delivers three unique game modes: Campaign, Multiplayer, and Zombies. Campaign is a return to the gritty, military roots of the franchise, while boldly looking ahead, delivering a rich and engaging narrative that is unlike anything to date in a Call of Duty game. The player will embark on a classically-styled story about grand scale warfare, set in a future where human conflict has spread throughout our solar system. Multiplayer combines popular mechanics such as the chained-based movement system, with a load of gameplay innovations to deliver one of the deepest and most engaging online experiences in gaming. The new Zombies mode will thrill co-op players with an original, distinctive approach and an uproarious narrative sure to excite fans. The title introduces stunning, multi-planetary environments, new weaponry, and all-new player abilities.
