What you’ll be doing

Strike group. The carrier group pushes along an island coast as F-35 strikes and escort missiles hit shore targets.
Boss fight. Escorts, F-35s and missiles pound the Tempest Flagship at night until it blows apart.
Lane defense
Build towers on pads along a shipping lane, upgrade them through three tiers, and keep the convoy alive through waves of boats, drones, aircraft and missiles.
Ballistic threats
Later waves fire ballistic missiles with a marked impact point. Only Aegis Ashore’s SM-3 interceptors can stop them.
Fire support
Call in F-35 strikes, naval gunfire, an F-22 patrol or Tomahawks from the carrier group, each on its own cooldown.
Upgrade and repair
Spend the money you earn from kills to take towers through three tiers, repair damaged ones, or sell them.
Strike group
Command a carrier, cruisers, destroyers and a submarine in real time. Spend Command Points on support and replacement destroyers.
Air missions
Between the naval battles, fly a launcher hunt, a carrier launch and an air dominance sweep.

Questions

How do I get Operation Trident?

It’s a one-time in-app purchase inside Final Siege on iPhone, iPad and Android. Tap a locked Operation Trident theater in the level select to open the store.

Do I have to finish the base campaign first?

No. The missions are playable as soon as you buy the expansion. They start at the difficulty of the middle of the base campaign.

Is it in the browser demo?

No. The browser demo is the first theater of the base game. Operation Trident is only in the iOS and Android versions.

How is it different from the base game?

Most missions put you in command instead of in the cockpit: you build defenses or move a fleet, and call in aircraft and missiles from the carrier group.
