Black Key
Black Key is only worth carrying when your run is already strong enough to turn Fort Istria into a Dreadnought vault finish.
Dreadnought is the end of the colored-key chain, a late high-tier payoff stop where Black Key turns into the black vault run.
Dreadnought is where the colored-key route stops being theory and starts paying out. It has its own large loot table with 29 active slots, and Black Key opens the black vault inside the Dreadnought (Bismarck). In practice, that makes Dreadnought the finish line for crews that already survived Fort Istria, kept the Trampler alive, and still have enough fuel and hull to leave with the vault loot.
You reach Dreadnought after completing the colored-key chain far enough to secure Black Key, which opens the black vault inside the Dreadnought.
Black Key is only worth carrying when your run is already strong enough to turn Fort Istria into a Dreadnought vault finish.
Fort Istria is a fixed fort worth routing for Black Key progression and guaranteed NZ Mk2 Energy Rods at each extraction exit.
Evacuation Zone is the place where your run stops being loot theory and becomes a real extraction commitment.
Fort Istria is a fixed fort worth routing for Black Key progression and guaranteed NZ Mk2 Energy Rods at each extraction exit.
Kaiserplatz is the landmark that turns a loose Green Key into Blue Key progress, so it only pays when your run can survive the whole key chain.
Meere Sauge is the point where the colored chain starts getting expensive enough to punish greed.
Radio Tower is the object that turns an exit option into a real extraction gamble, so timing matters more than bravery here.
Segen is the last landmark before Fort Istria, so it only matters when your run can still justify the final push.
Black vault payout
The whole key chain only cashes out once Dreadnought is reached and cleared.
Dreadnought is not just another landmark with good boxes. It has its own large loot table and the black-vault payoff tied directly to Black Key.
The stop becomes a trap when a crew reaches it without enough hull, meds, or extraction margin. A dead Trampler at the end of the chain turns every earlier key step into wasted risk.
It is the late-route destination tied to Black Key and the black vault, with its own large loot table.
Yes. Black Key opens the black vault inside the Dreadnought.
