How to get the Rail Depot Storage Key
No video we checked shows where this key drops yet. Keys turn up as loot, a Lieutenant you kill may drop the key to their own loot room, and some Story Missions pay keys as rewards. We add the drop here once two players show it.
Keys can go in your Stash between deployments, but anything outside a Secure Slot is lost if your exfil fails. Tick the keys you have in the MW4 DMZ key finder; the list stays in your browser.
