Final Siege expansion
Dark Vengeance
Final Siege, in full 3D.
Dark Vengeance adds 12 missions to Final Siege, flown in third-person 3D. Take an experimental fighter-bomber low through canyons and fjords to destroy air defenses, sink warships and beat enemy aces.
12 missions, 2 theaters. A one-time in-app purchase in Final Siege for iPhone, iPad and Android.
What you’ll be doing
- Defense suppression
- Hunt AAA, SAM sites and mobile AA. Knock out a site’s radar and its launchers go quiet.
- Strike
- Drop bombs on bunkers, relays and pylons with a marker that shows where they’ll land.
- Anti-ship
- Attack corvettes and destroyers hiding deep in the fjords, under a wall of guns and missiles.
- Dogfights
- Lock missiles onto fighters arriving in pairs, then duel the enemy ace known as Wraith.
- Boss stages
- Each theater ends against something huge: the Bastion fortress, and Admiral Skarn’s flagship.
- Barrel rolls
- Flick sideways to roll through gunfire. Time it at the last moment and incoming missiles overshoot.

Two new theaters
Each theater is six missions and ends with a boss.
Operation Black Canyon
The Redrock Range, against the Ashen Legion. Boss: The Bastion.
Warlord Kael has buried his air defenses in the canyons of the Redrock Range, where no ordinary jet can reach them. Aegis is sending the Dark Vengeance.

Operation Northern Fury
The Hvit Fjords, against the Glacier Directorate. Boss: Skarn’s Flagship.
Admiral Skarn’s fleet hides deep in the northern fjords under a wall of guns and missiles, raiding the free coast at will. Fly in low and break it.

Questions
How do I get Dark Vengeance?
It’s a one-time in-app purchase inside Final Siege on iPhone, iPad and Android, separate from Operation Trident.
How do the controls work?
The jet flies forward on its own. Drag on the left half of the screen to steer and flick sideways to barrel-roll. The right side has buttons for the gun, missiles, bombs, flares and boost.
Will it run on my phone?
It uses the same lightweight renderer as the rest of Final Siege, with low-poly terrain and models, and supports the same phones as the base game: iPhone XS or later on iOS 17, and Android 7.0 or later.
Is it in the browser demo?
No. The browser demo is the first theater of the base game. Dark Vengeance is only in the iOS and Android versions.
New to Final Siege?
