Modern Warfare 4 campaign trailer sets up a global war

The campaign trailer for *Call of Duty: Modern Warfare 4* presents a darker continuation of Infinity Ward’s rebooted storyline, centred on a North Korean invasion, a fugitive Captain John Price and a global weapons threat. The trailer debuted on September 17, 2026, ahead of the game’s October release. [1][2]

A two-front story

The campaign is split between the collapsing front lines of the Korean Peninsula and Price’s covert personal mission elsewhere in the world. Activision’s official story summary says North Korea launches a full-scale invasion of South Korea while Price operates off the books, pursued by forces connected to his past. [2]

That structure gives the campaign two distinct perspectives. Players will take the role of Private Park, a young South Korean soldier experiencing live combat alongside his squad. They will also follow Price, now described as an operator-turned-outlaw working outside the system he once served. [3]

The trailer expands the conflict beyond a conventional military invasion. Official promotional material refers to a powerful weapon that could destabilize the global order if it falls into the hands of Vladimir Makarov, the series’ recurring antagonist. Price’s search appears to intersect with that threat, creating the campaign’s central link between a local war and a wider international crisis. [1][2]

A globe-spanning campaign

Although Korea is the campaign’s main setting, the announced missions move across several locations. PlayStation’s Canadian listing identifies trench warfare in Korea, close-quarters fighting in New York, high-speed pursuits through Paris, SAS night raids in Mumbai and large-scale assaults to retake occupied territory. [3]

That variety is consistent with the series’ established cinematic format, but the campaign appears designed to contrast large battlefield sequences with more intimate operations. The official description places Park among soldiers trying to survive a collapsing front, while Price works through clandestine networks and shifting alliances. [2][3]

The Tokyo Game Show trailer’s official description also highlights Price’s conflict with former allies and an alliance with a former enemy. That detail suggests the campaign will continue the recent *Modern Warfare* games’ focus on uncertain loyalties rather than presenting the conflict as a simple battle between fixed sides. [1]

Activision has not publicly disclosed the campaign’s mission count, total playtime or full ending. Those details should not be inferred from the trailer or from the currently published story summaries.

When Canadian players can play

*Modern Warfare 4* is scheduled to launch worldwide on October 23, 2026, for PlayStation 5, Xbox Series X|S, Xbox on PC, Steam, Battle.net and Nintendo Switch 2. Microsoft has also identified the title as an Xbox Play Anywhere release. [4]

Digital pre-orders receive campaign early access beginning October 16, one week before the general launch. Activision says the benefit applies to players who digitally pre-order or pre-purchase either the Standard Digital Edition or Vault Edition on the listed platforms. [2]

For Canadian PlayStation customers, the official store lists the PS5 Standard Edition at $89.99 and the Vault Edition at $129.99. The listing also identifies the game as a PS5 title with PS5 Pro enhancements. [3] Prices and availability can vary by platform, retailer and applicable taxes, so the PlayStation listing should not be treated as a universal Canadian price for every edition.

More than a campaign

The campaign is one part of a broader package. Activision and PlayStation describe a multiplayer launch featuring 12 new core six-versus-six maps, alongside larger maps that combine vehicle and infantry combat. [3]

The game will also include DMZ, an extraction-focused mode in which players deploy alone or with a squad, collect equipment and attempt to escape with their haul. The mode is framed as an off-the-books operation to recover advanced military technology left behind by the conflict. [3]

That broader design matters because the campaign’s Korean conflict and weapons plot appear to provide the narrative foundation for the multiplayer and DMZ settings. However, Activision has not said that completing the campaign will be required to access those modes, and the official listings present them as separate experiences. [2][3]

What the trailer confirms — and what it does not

The trailer confirms the campaign’s tone, its central conflict and the return of Price as a major character. It also establishes that the story will move between South Korea and several international locations, with Makarov and a potentially catastrophic weapon at the centre of the threat. [1][2][3]

It does not confirm every character’s fate, the full sequence of events or whether the campaign will include branching outcomes. Those questions remain open until Activision releases additional gameplay footage, previews or the game itself.

For now, the clearest takeaway is that *Modern Warfare 4* is positioning its campaign as a direct escalation of the rebooted series: a war that begins on the Korean Peninsula, spreads across multiple cities and forces Price into a confrontation with both his enemies and his former allies. Canadian players who pre-order digitally can begin that story on October 16; everyone else is scheduled to join on October 23. [2][3][4]
