MW4 Island Hidden Bunker: Code 0008 & Entry Route
Find the riverbed hatch, solve the checkpoint clue and distinguish the entrance from its interior crate.
Quick answer
Enter 0008 at the Island Hidden Bunker hatch. It is not the Small Island Container (6789). The clue adds the numbered Infantry Checkpoints along the river to make 8; the keypad keeps four digits.
Find the entrance
Look at the riverbed below the bridge, against the cliff on the western river island. Community maps place the hatch near 615,169; another guide gives the adjacent 615–616,168 grid. These describe the entrance and nearby interior, rather than separate bunkers. Use the concrete hatch and keypad as the final visual check, not the approximate coordinate alone.
Collect the two notes and crate
Read Island Hidden Bunker Note on the wall beside the hatch. Open the hatch, descend the ladder and inspect the desk for NW Bunker Note (also called NW Island Bunker Note). Open the yellow supply crate inside separately. Opening the hatch, reading a note and opening the crate are three different checks in the collection tracker.
