Chain tips
SAFESThe Green Key is a lottery — sweep every landmark with safes; the other keys are guaranteed behind doors.
FORT MINESFort Istria has no enemies, but the minefields eat Tramplers too — approach on foot or clear a path.
BOX KEYPick up Box Keys along the way (on desks and counters) — they open locked boxes across landmarks.
TIMINGThe Black Key is not consumed until you find the Dreadnaught — carry it into Storm Dive runs during the Final Extract event.
