Walkthrough
Mayhem and Out in the Cold
Missions 1–2: Hajin City and the New York nightclub, with Skeet Shooting, Safety's On and Can't Touch This
Following Orders and Hired Gun

Losing Ground and Traffic
Missions 5–6: the mortar for Raining Thunder in Hajin City, then Paris
Gone Dark and Assassins
Missions 7–8: Mumbai, then the three door codes and separate runs for Pacifist and Revenge
Survivors

Stranded
Mission 10, the open map: all 26 yellow crates, every keypad code, the sewer route, Base Camp repairs and the notes, for four trophies
Defection and Counter Attack
Missions 11–12: the airbase raid, retaking Hajin City with the Spotter Scope, and Long Shot
Escape and Entrenched
Missions 13–14: the breakout and the safe code for Never Forgotten, then Trench Broom

Collectibles & Trackers
Trophies & Achievements
Eight gold and ten silver, all from the Campaign: no platinum, no bronze and nothing from Multiplayer or DMZ. Worth 1,000 Gamerscore on Xbox. Two need a difficulty for the whole game (any, then Realism), three need one for a single mission, and Pacifist and Revenge need separate runs of Assassins.
64 · TrackerNotes
Sixty-four notes in three missions: four in Following Orders, 58 in Stranded and two in Escape. Noteworthy needs 50 (whether the four in Following Orders count is disputed: see the trophy); No Stone Unturned needs the four in Following Orders. Stranded is the only mission with a counter, shown as X/58 in the backpack. Map coordinates are the ones on the Stranded tac map.
26 · TrackerYellow Supply Crates
Twenty-six yellow crates, all in Stranded (mission 10), for Time to Crate; they also give the supplies that pay for the Base Camp repairs. Twenty-four stay put; one rides the train and one a convoy truck. Six are behind keypads, and their codes are below.
Guides & Reference
What We Know
The confirmed facts kept apart from the ones Activision has not stated: dates, platforms, modes and credits on one side; install sizes and exact frame rates on the other, and the campaign length the reviews disagree on.
GuideStory and Setting
Two protagonists, a war on the Korean Peninsula and a weapon changing hands: the setup as Activision states it, the cast as reported, and nothing past the setup.
GuideGameplay
The movement and gunplay changes Activision published, next to what the people who actually played them at Infinity Ward and in the beta reported back.
GuideEditions and Access
What is in each edition, which bonus needs which purchase, who gets the Campaign a week early and who does not, and why Game Pass is not an option this year.
GuidePlatforms and Performance
Where it runs and what it needs: Activision's PC requirements in full, the Switch 2 build's confirmed features, and what the console figures in circulation actually rest on.
GuideMultiplayer and DMZ
Everything Activision has described about Multiplayer, Kill Block, Ground War and DMZ: the six maps the beta ran, the modes with their rules, and the FOB behind the extraction mode.
GuideMultiplayer Maps
The twelve Core 6v6 maps, the three Ground War maps in Hajin, the four Gunfight 2v2 maps and Kill Block, with where each one is set, and the date Shipment arrived.
GuideWeapons
Every Multiplayer weapon at launch by class, with the Player Level that unlocks it. Seven unlock levels are disputed.
GuideProgression & Prestige
How the Player Level works, the choice between Classic and Regular Prestige, Prestige Master, and the separate DMZ level.
GuideDMZ Guide
How a run in Hajin goes: playing solo or in a squad, getting out by helicopter, what you lose when you die, and how to rescue an Operator.
GuideFAQ
Each answer names its source, and says "nobody has said" where that is the honest answer.
GuideRelease and What Comes Next
Every date Activision has put in writing, what the two betas actually contained, and what is promised for after launch.
About this guide
Call of Duty: Modern Warfare 4 (23 October 2026, on PlayStation 5, Xbox Series X|S, PC and Nintendo Switch 2) is published by Activision and led by Infinity Ward; digital pre-orders have had the full campaign since 16 October, physical editions have not. The story follows a South Korean squad on a collapsing front line while Captain Price runs a war of his own. The guide walks through all 16 Campaign missions in 9 chapters, with every note, supply crate and keypad code, and a checklist for all 18 trophies. Beside it sit what the open beta showed of multiplayer and DMZ, the editions and the PC requirements. Where the publisher's own pages contradict a storefront (who developed it, what the editions are called, what they cost), the page shows both.
