MW4 Campaign Guide: All Missions, Achievements, Keypad Codes and Stranded Collectibles

Quick facts and how to read the chips

Modern Warfare 4 is a single-player campaign from Infinity Ward, and its early access opened on 16 October 2026, a week ahead of the 23 October release. Every page we found is one to four days old, so we sorted what we know into four chips and we use them throughout. Seen in our playthrough means it was on screen in our own Stranded recording. Confirmed means two or more independent sources agree, or a primary source states it. Unconfirmed means one source only, or sources that disagree. Being mapped means nothing has been published yet and we will update after launch.

All 18 MW4 campaign achievements and trophies

This is the full list with the unlock text exactly as PowerPyx and the PlayStation listing give it. On Xbox, Hold the Line and Was it worth it? are worth 100G each and the other 16 are worth 50G, which adds up to 1,000G (one source, but the sum checks out). Dayngls Game Guides reports no missable achievements because mission select lets you replay any mission, and you need at least two playthroughs to finish the list. Names vary a little between sites: Trench Broom is misspelled Trench Boom in one place, and Destructoid shortens Was it worth it? to Worth It. We use the PlayStation text. Several methods below come from a single guide, and we mark each of those until a second source or our own run backs it up.

The achievement run plan

Most of the list falls out of one Hardened pass, which also covers the difficulty gates on Safety's On and Revenge. Pacifist and Can't touch this come off mission select afterwards, and Realism goes last because nothing else needs it. Two things could change this plan. We do not know whether Realism asks for a full clear first. And Can't touch this needs Veteran or higher, so it should also count on the Realism run, because Realism sits above Veteran, but that is unconfirmed.

Every keypad and safe code in the campaign

This is the master table. Codes outside Stranded are few: a toolbox, a wall safe and three doors. The eight Stranded codes are all here as well, with a longer note on each in the Stranded section. One claim is still open. A single source says the Stranded codes rotate weekly through notes you find on enemies, while every other site lists fixed codes. We have not seen a change, so we treat that as unconfirmed. If it turns out to be true, the useful thing to learn is where the code notes are, not only the codes.

The 16 MW4 campaign missions

One card per mission, in story order. Rewards come from the mission lists we read and each mission gives one. Where a mission has no walkthrough yet, the card says Being mapped, updates after launch, and we will fill it in rather than guess.

Stranded at a glance: three targets in any order

Stranded is mission 10, and it is an open zone: a snowy North Korean island map at night, in a blizzard. You choose the order of three sabotage targets. The target descriptions come from one site, allthings.how, and we have not yet walked all three ourselves, so they carry the unconfirmed chip. The open map stays open after the story, so you can come back for the collectibles. That is one source's claim too. The achievements tied to Stranded are Time to Crate, Scavenger, Incoming! and Noteworthy.

Base Camp, the workbench, Jae and Supplies

You play with Jae, an AI squadmate who runs the Base Camp workbench. His line when you first reach it is: With enough supplies, I could fix our gear and equipment. Supplies are a single currency with a wrench icon, picked up from the world and from bodies. The bench charges a fixed number of Supplies per job. If you cannot pay, the screen says NOT ENOUGH SUPPLIES TO REPAIR THIS. Refilling ammo costs nothing. Everything in the table below is from our own recording.

The Gun Wall and the 11 outposts

The Gun Wall is a permanent unlock board. The first time you pick up a weapon or an item, it is unlocked on the wall for good, with a toast such as New Weapon Unlocked on Gun Wall: Mosin-Nagant, or New Equipment Unlocked on Gun Wall: Molotov Cocktail. We saw both. There are 11 outposts, and clearing one gives you fast travel. We saw the toast 1/11 Outposts Cleared, Fast Travel Unlocked, which settles both questions that the written guides left open. The outpost names below come from allthings.how, and only the count is ours.

Stranded keypad codes: all eight

Eight containers and bunkers in Stranded want a code. Most sites agree on them. Showgamer adds map coordinates, which we have not tested. A keypad crate shows on the tac map once you find a note or map that points to it, and the map text reads Keypad Puzzle Supply Crate.

All 26 Stranded yellow supply caches (Time to Crate)

The counter on screen reads n/26 Yellow Supply Caches Opened, and opening all 26 unlocks Time to Crate. The list follows the route order from allthings.how, so the numbers are a route, not the order you will open them in. Our own run opened the sewer crate first, which the list calls number 2, and the cliff Scout Drone crate second, which the list calls number 18. The list is a single source apart from those two, so the other 24 rows carry the unconfirmed chip. If you open a crate that is not on it, tell us and we will fix the list.

Stranded notes by zone and the Noteworthy achievement

Our screen reads NOTES FOUND n/58 in Stranded, and note 8 was the sewer note beside our first crate. Noteworthy asks for 50 different notes in the whole campaign, and there are 64 if the one-source total holds: 4 in Following Orders, 58 in Stranded and 2 in Escape. So you can skip 14. The zone ranges below are from allthings.how and still need a second pass. A note you read also adds the places it mentions to the tac map, and the notice reads Location or locations mentioned by note added to tacmap.
