The publisher says the offer applies to all platforms, and the campaign will be available to pre-order customers beginning October 16, 2026, ahead of the title's wider release on October 23, 2026.
Activision has also confirmed the game will release on Nintendo Switch 2.
The announcement frames Modern Warfare 4 as a darker, more consequential entry in the long-running Call of Duty franchise.
Infinity Ward, the studio behind the Modern Warfare subseries, described a narrative centered on a full-scale invasion on the Korean Peninsula and the cascading global consequences that follow.
The studio outlined two parallel storylines: a young squad of South Korean troops fighting on collapsing front lines, and Captain Price conducting an off-book campaign from the shadows.
Activision says the intersecting arcs drive the game's escalation to a powerful and emotional breaking point.
In journalistic terms, Infinity Ward summarized the campaign as delivering varied combat set pieces across multiple theaters: trench warfare on the Korean front, close-quarters engagements in New York, high-speed chases through Paris, SAS night raids in Mumbai, and large-scale operations to reclaim occupied cities.
The publisher emphasized that multiplayer will focus on grounded, precise combat with fluid movement and player choice, while the DMZ mode positions players as off-the-books assets executing extraction runs that require tactical decisions about objectives and timing.
As part of today's reveal, Activision provided a first look at a major campaign mission titled "Losing Ground," which follows the South Korean squad through intense ground-level combat and the chaos of a collapsing frontline.
The preview footage and developer commentary accompany the pre-order announcement.
Activision also noted that pre-orders for the Nintendo Switch 2 version will open soon and that a console beta for the system is planned.
The publisher has positioned the early campaign access as the key pre-order bonus across platforms, allowing players to experience the single-player story a week before the game's full launch.
For players tracking platform news, the listing of Nintendo Switch 2 alongside other systems underlines Activision's cross-platform rollout for Modern Warfare 4.
Further details, including pre-order windows, platform-specific editions, and multiplayer beta dates, are expected from Activision and Infinity Ward in the lead-up to the October release.
