Call of Duty: Modern Warfare 4 is giving digital buyers a week-long head start on the campaign. The official announcement confirms that Campaign Early Access begins on Friday, October 16, 2026 for players who pre-order or pre-purchase the Standard Digital Edition or Vault Edition on Steam, while the full game is still scheduled for Friday, October 23, 2026.
The early-access window is tied to the story mode only, and the new campaign leans hard into a frontline war setup. Players will step into the boots of Private Park, a young South Korean soldier caught in a North Korean invasion, while Captain Price is running his own off-book pursuit tied to a weapon that could tilt the conflict.
The campaign description points to a mix of large battles, covert operations, combined-arms fighting, and cinematic set pieces. The same notice also says the game will be available globally on PC via Steam on October 23, 2026, and that Infinity Ward is building a native Nintendo Switch 2 version with Digital Legends.
For anyone planning to jump in early, the key detail is simple: pre-order digitally on Steam, and the campaign opens on October 16. The official Call of Duty preorder post also points to more details on editions, rewards, and the Loyalty Discount ahead of the Open Beta and launch.
