On Stranded, the keypad doors are more than optional detours; they give a long sweep across the map a clear purpose. Check the paper beside each lock before entering a code. Some clues use number patterns, while others point to nearby landmarks. At Base Camp, the first crate stands beside the communications tower. Its note counts upward by sixes and gives 0024. Open it early if you can: the map inside marks the other locked crates and cuts down on backtracking. Then head north of the encampment. Reach the cliff by the wooden steps or the outer dirt road; its note decreases by 2,900 each step, giving 0600. If you split your time between the campaign and multiplayer practice, MW4 Bot Lobbies can be part of the wider routine, but careful exploration is what makes this route pay off.

Four More Crates on the Route

From the cliff, follow the river road towards the highway billboard. The third crate has a direct counting clue, with 1234 as the answer. Continue south to the fuel vehicle south of the Jamming Station for crate four; its pattern rises by 902 per step and ends at 8609. The fifth lock is in the Southeast Village, near the main bridge. Its paired-digit puzzle gives 0078, so watch for patrols before stopping to work it out. The last shipping container sits on a small island in the river. Clear the perimeter watchtower to reach it, then follow the single-digit climb to 6789. Handling these four in sequence keeps you moving and avoids a needless trip back across the map.

Two Underground Keypads

The underground sites ask for a different kind of thinking. Farm Field is reached through a hatch northwest of the main encampment. Its note names four Logistics Stations and the values 10, 20, 100 and 200. Add them together and enter 0330. The other site, often called Island or Riverbed, has a concrete door on the western cliff near Infantry Checkpoint 1. Its clue concerns the Infantry Checkpoints along the river, rather than a number sequence. Follow the location-based count and use 0008. In both places, match the note to the right landmarks before moving underground; it's easy to mix up these clues when you're rushing between objectives.

What the Full Sweep Delivers

Opening all six crates and both facilities delivers more than a cleared corner of the map. The first cache's intel helps you locate the remaining crates, while the hidden rooms hold high-tier weapons and custom gear attachments. The rare weapons can be brought back to the primary assembly point, and unlocking all eight keypad doors contributes to the campaign completion trophy requirements. Keep a rough route in mind, but don't skip the notes: they explain why each code works and help make the search feel deliberate. If you'd rather use some of your time to improve your multiplayer setup, cheap CoD MW4 Boosting can sit alongside a completion-focused run. Once you know what each clue is asking, the full sweep is much less of a slog.
