Modern Warfare 4’s campaign collectibles are concentrated in three replayable missions. The 64 campaign notes are in Following Orders (Mission 3), Stranded (Mission 10), and Escape (Mission 13). Replay a completed mission from the campaign menu, then track notes, Yellow Supply Caches, contraband, Supplies, and Gaz’s dog tags separately. The game’s exact Mission Select labels and save behavior can vary by platform or patch, so verify the result in your own achievement or trophy list after each run.
Activision says the campaign contains 16 missions, with early access beginning October 16, 2026, and full launch on October 23, 2026. Its announcement confirms campaign completion rewards become usable in Multiplayer and DMZ at full launch, but it does not document replay or collectible-save behavior. The replay and collectible counts below come from published campaign guides, not official Activision statistics.

Which Modern Warfare 4 missions should I replay for collectibles?
Replay only Missions 3, 10, and 13 for the collectible-related objectives covered by the available guides. The mission map below separates every item type so you can decide what to collect on each run instead of searching all 16 missions.
| Mission | Collectibles and resources | Related objective | Tracking information |
|---|---|---|---|
| Following Orders (Mission 3) | 4 notes; 4 contraband items | No Stone Unturned | One note route uses toolbox code 214; a mission choice can block the fourth note for that run |
| Stranded (Mission 10) | 58 notes; 26 Yellow Supply Caches; Supplies | Noteworthy, Time to Crate, and Scavenger | The backpack reportedly shows notes as X/58; all base-camp gear requires 195 Supplies |
| Escape (Mission 13) | 2 notes; Gaz’s dog tags in a safe | Never Forgotten | The safe code reported by the guide is 8410 |
Across those missions, the guide reports 64 notes: four in Following Orders, 58 in Stranded, and two in Escape. Notes are not required to complete the story. The same guide reports that completed missions can be replayed, allowing you to return for missed items.

For the full location-by-location route and the container context for each code, use the published Modern Warfare 4 collectibles guide. Item numbers in a route may change if you pick things up in a different order, so treat the item’s location and description—not its number—as the reliable reference.
Can I replay a completed campaign mission?
Yes, the campaign guide says completed missions can be replayed. However, Activision’s campaign announcement does not specify the exact Mission Select interface, whether a replay overwrites a previous checkpoint, or how every collectible counter behaves on every platform and patch.
Use this platform-neutral process:
- Finish the mission once. Return to the campaign hub after the completion screen rather than closing the game during the final transition.
- Open the campaign mission list. Look for a Mission Select, Replay Mission, or similarly named option. The label can differ by platform, edition, language, or update.
- Choose the target mission and load it. For collectibles, select the mission that contains the missing item; there is no reason to replay the other 13 missions for the counts listed here.
- Collect the item and finish the relevant interaction. Reading a note, opening a Yellow Supply Cache, taking contraband, or opening the dog-tag safe may be required before the game records it.
- Exit through a normal completion or save point. Because the sources do not document whether abandoning a replay writes progress, do not assume that collecting an item and immediately quitting will save it.
- Check the game’s counter and your platform achievement or trophy list. Use the backpack counter in Stranded and the platform overlay as confirmation rather than relying on memory.
If Mission Select is missing, first confirm that the original mission reached its completion screen and that you are in the campaign mode rather than a multiplayer or DMZ menu. A patch can also change menu wording; the guide’s replay claim should not be read as a guarantee that every build exposes identical options.
How do I clear every collectible in Following Orders?
Following Orders contains four notes and four contraband items. The guide associates collecting all of them with No Stone Unturned, making Mission 3 the shortest of the three collectible replays but also the one with the most important route decision.
Use the red-toolbox code
After finding the recipe note described by the guide, enter 214 on the red toolbox. The code is tied to that toolbox interaction; it is not one of the eight Stranded keypad codes listed later.

Watch the mission choice
The guide warns that a choice in Following Orders can make the fourth note inaccessible during that run. If your note total stops at three, do not assume the note is permanently missable. Replay Mission 3, make the other choice, and revisit the note route. Because the source does not document the exact choice label in a platform-independent way, follow the location guide’s story context rather than guessing from a generic mission checklist.

Verify both item categories
Do not stop after reading all four notes. Contraband is tracked separately, and No Stone Unturned is associated with four notes plus four contraband items. Record the two totals independently in a checklist so a complete note run does not hide a missed contraband pickup.
What is the best way to collect everything in Stranded?
Stranded is the main completionist mission: it contains 58 notes, 26 Yellow Supply Caches, and the Supplies needed for the base-camp upgrade objective. Plan a deliberate sweep instead of trying to combine a speedrun with a first-time collectible hunt.
Use the backpack as the note counter
The guide reports that the backpack displays notes as X/58. Check the counter when you enter the mission, after major sections, and before leaving. If the value does not increase after an interaction, confirm that you actually picked up or read the note and that the game has finished its collection animation.
Keep three Stranded goals separate
- Notes: 58 total in the mission; Noteworthy requires reading 50.
- Yellow Supply Caches: 26 total; opening all of them is associated with Time to Crate.
- Supplies: collect 195 to upgrade all base-camp gear for Scavenger.
The goals overlap spatially but are not interchangeable. A backpack total of 58 does not prove that all 26 caches were opened, and opening every cache does not prove that you gathered 195 Supplies. Mark each category in a separate column.

Enter the reported Stranded keypad codes
The collectibles guide lists these eight codes for containers and bunkers in Stranded:
| Code | Use it for |
|---|---|
| 0024 | A listed Stranded container or bunker |
| 0008 | A listed Stranded container or bunker |
| 0078 | A listed Stranded container or bunker |
| 8609 | A listed Stranded container or bunker |
| 0600 | A listed Stranded container or bunker |
| 1234 | A listed Stranded container or bunker |
| 0330 | A listed Stranded container or bunker |
| 6789 | A listed Stranded container or bunker |
The source gives the codes but does not make them a substitute for the route. Match each code to the location and puzzle context in the guide. If your item numbering differs, that is expected when the pickup order changes; the code itself and the physical location are the useful anchors.
How do I finish the Escape collectibles?
Escape (Mission 13) has two notes and Gaz’s dog tags in a safe. The guide associates the dog tags with Never Forgotten.
When you reach the safe described in the route, enter 8410. Collect the dog tags and confirm the interaction has completed before moving on. Then search the mission’s two note locations. Because the available source summarizes the route rather than documenting platform-specific HUD behavior, use the achievement or trophy list as the final confirmation for Never Forgotten.

| Achievement or trophy | Requirement reported by the guide | Mission or resource |
|---|---|---|
| No Stone Unturned | Collect four notes and four contraband items | Following Orders |
| Noteworthy | Read 50 notes | Stranded contains 58 |
| Time to Crate | Open all 26 Yellow Supply Caches | Stranded |
| Scavenger | Upgrade all base-camp gear using 195 Supplies | Stranded |
| Never Forgotten | Collect Gaz’s dog tags | Escape |
These are guide-reported requirements. The sources do not establish a universal rule for when an achievement or trophy pops during a replay, nor do they confirm whether every platform displays identical progress percentages. If an objective does not appear immediately, finish the mission, return to the campaign hub, and check the platform’s achievement or trophy page before repeating the route.
What is the most efficient replay order?
A practical order minimizes backtracking while keeping the counters understandable:
- Play the story normally through Mission 3. In Following Orders, collect the four notes and four contraband items. If the mission choice blocks the fourth note, note the missing count and plan a second run with the alternate choice.
- Replay Mission 3 immediately if needed. It is easier to resolve the choice while the story context is fresh than to leave one note for the end.
- Complete Mission 10 as a dedicated sweep. Carry a checklist for 58 notes, 26 caches, and 195 Supplies. Use the backpack’s X/58 value to detect a missed note, but do not treat it as a cache or Supplies counter.
- Replay Stranded for the missing category. If your note total is complete but a cache or upgrade requirement is not, focus the second pass on that category. The source does not document whether already collected items remain visually open or how replay overlays behave, so rely on your written checklist and current counters.
- Finish Mission 13’s two notes and dog tags. Enter 8410 at the safe and verify Never Forgotten after the mission.
- Review all objectives at the campaign and platform level. This catches the common mistake of completing every note while missing one contraband item, one cache, or enough Supplies for the final gear upgrade.
You do not need to collect every note to finish the story, and the guide’s 50-note requirement for Noteworthy is lower than the 64-note campaign total. A full completionist file should still target all 64 notes and separately close every cache, contraband, Supplies, and dog-tag requirement.
What should I do if a collectible is missing?
First identify the category and mission rather than restarting the whole campaign. The following recovery branches match the problems documented by the guides:
- Following Orders shows three notes: replay Mission 3 and take the alternate story choice; the guide says that choice can block the fourth note for a run.
- Stranded notes do not reach 58: compare the backpack’s X/58 value with your written route and revisit locations in the published guide. Do not rely on item numbers if your pickup order differed.
- All notes are present but an achievement is absent: finish the replay, return to the hub, and check the platform overlay. The sources do not guarantee instant unlock timing.
- A keypad rejects a code: verify that you are at the matching Stranded container or bunker, include leading zeroes, and check the route context. Codes such as 0024 and 0008 must be entered as four digits.
- Replay progress is unclear: do not promise yourself that a quit-to-menu action saved the pickup. Complete the mission or reach a normal save transition, then check the counter after returning to the campaign hub.
How does the campaign’s release timing affect this guide?
Activision’s official announcement describes a 16-mission Modern Warfare 4 campaign, with early access beginning October 16, 2026 and the full game launching October 23, 2026. It also says campaign completion rewards become available for Multiplayer and DMZ at full launch. The announcement does not explain Mission Select, collectible persistence, or platform-specific achievement behavior, so those details should be treated as subject to updates.

Frequently Asked Questions
Do I need all 64 notes to complete the campaign?
No. Notes are optional for story completion, and the reported Noteworthy objective requires 50 notes rather than all 64. Collecting all 64 is a completionist target, not a prerequisite for finishing the narrative.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Are the Stranded keypad codes different on each playthrough?
The guide presents fixed four-digit codes, including leading-zero entries such as 0024 and 0008. What can change is the numbering in a route if you collect items in a different order, so match the code to the correct container rather than an item number.
Can I unlock the objectives in separate replay sessions?
The available sources support replaying completed missions but do not document a universal cross-platform rule for how every objective combines progress from separate runs. Keep independent records for notes, caches, contraband, Supplies, and dog tags, then verify the platform achievement or trophy page after each completed replay.
Will replaying a mission reset my main story progress?
Activision’s announcement does not specify replay-save behavior. Treat a replay as a separate cleanup run, avoid assuming that it overwrites or preserves a particular checkpoint, and return through a normal mission-completion transition before checking your campaign state.
