Call of Duty: Modern Warfare 4’s campaign is playable now: Campaign Early Access opened on October 16 for digital pre-orders, at roughly 10am PDT / 6pm BST (17:00 UTC) according to Pure Xbox. Activision has not published an official Modern Warfare 4 campaign length or mission count. Infinity Ward calls it “probably the largest” Modern Warfare campaign it has made, and the last two Modern Warfare campaigns took roughly 3-4 hours (MWIII) and around 8 hours (MWII) to finish.
This guide collects what is actually confirmed about the campaign’s length, missions, story and difficulty, and which settings are worth changing before you start. Anything that comes from previews or estimates is labelled as such.
- Campaign length: not announced. Infinity Ward says it is probably the biggest Modern Warfare campaign yet; pre-launch estimates range from about 3 to 10+ hours.
- Missions: the count is not official. Confirmed settings include trench warfare in Korea, New York, Paris, Mumbai and the beta mission “Entrenched”.
- Two stories: Private Park on the Korean front and Captain Price on the run, with uneasy ally Valeria Garza.
- Difficulty: four levels, Recruit, Regular, Hardened and Veteran, according to GamingBible.
- Access: digital Standard or Vault pre-orders on every platform get the campaign now; the full game arrives October 23, and it isn’t on Game Pass at launch.

How long is the Modern Warfare 4 campaign?
There is no official answer yet. The closest thing to one came from Infinity Ward at the May reveal. Speaking to Game Rant, the studio’s Alex Norris said the team wants to carry players along “for as many hours as the campaign may take” and that “this is probably the largest Call of Duty campaign, as far as Modern Warfare goes, that we’ve put together.” He did not give a number of hours.
That makes the recent games the best yardstick. Here is how the reboot-era Modern Warfare campaigns compare:
| Game | Reported campaign length | Where the figure comes from |
|---|---|---|
| Modern Warfare II (2022) | About 8 hours | HowLongToBeat community data, as cited by VGC |
| Modern Warfare III (2023) | 3-4 hours | Early-access players, reported by VGC in November 2023 |
| Modern Warfare trilogy overall | 5-8 hours | Game Rant’s summary of the three reboot campaigns |
| Modern Warfare 4 (2026) | Not announced | Infinity Ward: “probably the largest” MW campaign. Estimates: 3-10 hours (GamingBible), “at least 10” (a Game Rant writer’s guess) |
Treat the MW4 estimates as estimates. If Infinity Ward is right, MW4 should comfortably beat MWIII’s 3-4 hours, which was widely criticised as short. Whether it beats MWII’s roughly 8 hours is the real question. Your own time will also depend on three things the studio has talked about: the difficulty you pick, how long you spend in the larger open missions, and the mission with branching outcomes (more on that below).
Early-access players will start posting completion times over the weekend, as they did for MWIII in 2023. We will add a reported range here once several sources agree.
Modern Warfare 4 campaign missions: what’s confirmed
Activision has not released a mission list, and the total number of missions isn’t official. GamingBible expects “around 12”, but that is a guess based on earlier games. What Activision and Infinity Ward have confirmed are the settings and a handful of set pieces:
| Mission or setting | What’s been shown or said | Source |
|---|---|---|
| “Entrenched” (Korea) | A large-scale assault with friendly infantry and armored vehicles to stop a nuclear power station falling into enemy hands; the first campaign mission ever playable in a Call of Duty beta | Call of Duty blog |
| Trench warfare in Korea | Park’s squad on the collapsing front line after North Korea invades | Activision announcement |
| Amphibious assault | Joint US/ROK marines in ground combat and a beach landing | Call of Duty blog (Tokyo Game Show trailer post) |
| City-wide assaults | Missions to retake occupied territory | Activision announcement |
| New York | Close-quarters combat | Activision announcement |
| Paris | High-speed chases; a car chase on Price’s side of the story | Activision announcement, Hardcore Gamer preview |
| Mumbai | SAS night raids | Activision announcement |
| Trainyard | A gunfight on Price’s story track | Hardcore Gamer preview |

Two stories that meet at the end
MW4 brings back the two-track structure of the older games. According to Infinity Ward’s briefing, as reported by Hardcore Gamer, the two stories run separately before converging at the end. Private Park’s missions are traditional grunt-perspective infantry combat in Korea, while Price’s are the globe-trotting, spy-thriller missions: the Paris chase, the trainyard and street-level platforming.
Rail missions, open missions and one mission with real choices
MWIII’s open-combat missions were one of its most criticised features, so it’s worth knowing what Infinity Ward has said about MW4’s structure. Norris told Game Rant that missions range from “a rail-ride mission where the player agency is a bit limited” to “a large-scale, open mission where the player gets to do so many things at their own pace.” He also confirmed that “there is a mission where the player has a lot of choices,” with “different outcomes and certain things like that, for certain missions.” If you want to see the other outcomes, that is the mission to replay once you’ve finished the story.
MW4 story: who’s who before you start
The campaign picks up after Modern Warfare III, in which Price killed General Shepherd. The official Tokyo Game Show trailer post sets out the cast:
| Character | Role in MW4 (official description) |
|---|---|
| Private Park Hyun Jun | Young South Korean soldier facing live combat for the first time; the main playable character on the Korean front |
| Captain John Price | Gone rogue; Task Force 141 has been disbanded and he is hunting a weapon headed for “the Archer” |
| Ghost and Gaz | Ordered to capture or kill their former captain |
| Kate Laswell | CIA station chief still in contact with Price, but growing wary of his methods |
| Valeria Garza (El Sin Nombre) | Las Almas cartel leader and Price’s reluctant ally |
| Commander Ri Ju-Young | Heard in the trailer ordering the peninsula shut down before the invasion |
| The Archer | Unidentified enemy the weapon is being delivered to |
You don’t need to have played the last three games. Hardcore Gamer notes that each Modern Warfare game has its own conflict, so you can start MW4 knowing little about the earlier ones, and Activision’s “The Story So Far” recap covers the key events of 2019-2023 in one read. The story does matter beyond this year’s game: Activision CMO Tyler Bahl has called MW4 “the epic conclusion of this recent series of Modern Warfare,” with a new Call of Duty sub-franchise being prepared for a future year.

Which MW4 campaign difficulty should you pick?
GamingBible lists four difficulty levels for MW4, from easiest to hardest: Recruit, Regular, Hardened and Veteran. Activision hasn’t published its own descriptions of each level for MW4, so check the in-game text when you start. Our suggestions below weigh the trade-offs; they aren’t based on play time with the game:
| Difficulty | Best for | Trade-off |
|---|---|---|
| Recruit | Seeing the story with as little friction as possible | Fastest run; the large open missions lose most of their tension |
| Regular | A first playthrough if you rarely play shooters | The baseline most “how long to beat” times will be measured on |
| Hardened | A first playthrough if you play Call of Duty multiplayer regularly | Slower progress and more checkpoint restarts, but you’re pushed to use cover and the new movement |
| Veteran | A second run, or trophy and achievement hunters | The longest route to the credits; MW4’s achievement list isn’t public yet, so we can’t confirm which rewards need it |
One practical point: if you plan to replay the campaign anyway to see the choice-driven mission play out differently, there’s little reason to grind your first run on Veteran. Finish the story on the level that suits you and save Veteran for the second pass.
Best settings to change before your first mission
The campaign is the mode where visual quality matters most, and on PC it’s where you can afford to trade frame rate for ray tracing. These are the options Activision and PC partner Beenox have confirmed in the official PC intel post, which says the game has “800+ customization options”:
| Setting | What it does | Suggestion for the campaign |
|---|---|---|
| Ray tracing | Supported in Campaign, Multiplayer and DMZ (reflections, shadows, lighting) | Turn it on for the campaign if your GPU allows; Activision’s “Ultra” spec for High RT at 4K upscaled is an RTX 5070 Ti or RX 9070 XT |
| Upscaler | NVIDIA DLSS 4.5, AMD FSR Redstone, Intel XeSS 3, or Filmic SMAA T2X (default) | Use the upscaler made for your GPU to pay for ray tracing; a new sharpness slider works with any of them |
| Depth of field | Now split into World Depth of Field and Weapon Depth of Field | Keep Weapon DoF for the cinematic aim-down-sights look; turn World DoF off if distant enemies look soft |
| Enhanced FOV (PC only) | Widens the view at the screen edges without shrinking the centre | Useful if you play at a lower FOV for comfort |
| HDR10+ | Adjusts contrast and brightness to your screen in real time | Enable it on a supported display instead of tuning sliders by hand |
| Advanced Shader Delivery | Delivers precompiled shaders at install so the game launches faster | Install the Xbox PC app first (Activision’s advice for every PC store) and update your GPU driver |
Two caveats. The built-in Benchmark Tool runs a simulated multiplayer sequence, so it tells you more about multiplayer frame rates than about the heaviest campaign scenes. And the PC version needs 115 GB of SSD space, TPM 2.0 and Secure Boot; our MW4 early access and preload guide has the full spec table.

MW4’s Steam store page lists these accessibility features: adjustable text size, camera comfort options, color alternatives, custom volume controls, subtitle options and captions, and “playable without timed input.” Camera comfort settings are worth a look before the vehicle chases if you’re prone to motion sickness.
How to play the MW4 campaign early
Campaign Early Access is a pre-order bonus for the Digital Standard Edition ($69.99) and the Vault Edition ($99.99) on Xbox Series X|S, Xbox on PC, PS5, Steam, Battle.net and Nintendo Switch 2, according to the Call of Duty blog.
