MW4 Island Hidden Bunker Code (0008): Note, Location and Infantry Checkpoints
The Island Hidden Bunker code in Modern Warfare 4 is 0008 (enter all four digits, not 8). The bunker is in the campaign mission Stranded (mission 10), on the riverbed island below the bridge, at the foot of a large cliff, at tac-map coordinates 615, 169. The note by the keypad says the code is the sum of the outpost numbers of the Infantry Checkpoints along the river: 1 + 2 + 5 = 8, which you enter as 0008. The code is the same for every player, so you don't have to clear the checkpoints first. Inside, a trapdoor drops you down to supplies, a yellow supply crate and a second note on the desk by the radio.

How to open the Island Hidden Bunker
- Clear Infantry Checkpoint #1 (around 632, 168) to unlock it as a fast-travel point, or travel there on foot. It is the closest fast-travel point to the bunker.
- Head west across the river and follow the cliff face. The entrance is a concrete structure down in the riverbed, not on the high ground. Open the tac-map and move the cursor until it reads 615, 169.
- Go in and read the note on the wall next to the keypad. It counts toward your notes.
- Type 0, 0, 0, 8 on the keypad. Keep the three leading zeros, because the keypad needs four digits.
- A trapdoor opens. Drop down, read the second note on the desk by the radio and open the yellow supply crate.
Island Hidden Bunker note explained: where 0008 comes from
The note tells you the code is the sum of all outpost numbers for the Infantry Checkpoints along the river. Outposts only show their numbers on the tac-map after you clear them. The checkpoints along the river are #1, #2 and #5:
1 + 2 + 5 = 8, and the keypad takes four digits, so the code is 0008.
Some guides read the note as a count of the outposts along the river instead. Either way the answer is 8, so the code doesn't change. A note at the SAM site in Stranded also writes the code out for the "west island bunker" (0008), together with the Farm Field bunker (0330) and the river island container (6789).
Island bunker code not working?
| Problem | Fix |
|---|---|
| Typed 8 and nothing happened | The keypad needs four digits: enter 0, 0, 0, 8 |
| Wrong island | The Small Island container (618, 132, near a watchtower) is a different lock and uses 6789. 0008 is only for the hidden bunker at 615, 169 |
| Wrong bunker | The Farm Field Hidden Bunker (631, 127) uses 0330: see the Farm Field bunker code |
| Can't find the entrance | It is down in the riverbed at the foot of the cliff. Line the tac-map cursor up with 615, 169 |
| Missed it and finished the mission | Replay Stranded from Mission Select. The bunker and its notes are still there |
The code is fixed for every player and every playthrough.
Do you need to clear the Infantry Checkpoints first?
No. 0008 works straight away. Clearing the checkpoints is still useful: each cleared outpost shows its number on the tac-map and becomes a fast-travel point, and the bunker's yellow supply crate is one of the 26 you need in Stranded for the Time to Crate achievement. Crate rewards can vary between playthroughs.
