Explore Operation Trident
Final Siege is a vertical-scrolling arcade shooter in the spirit of 1942. Fly modern jets, bombers, warships, submarines and an AC-130 gunship across 30 missions against fictional tyrant regimes, with two expansions that add tower defense, fleet command and full 3D flight.
The campaign keeps changing what you fly. One mission you’re dogfighting, the next you’re steering a destroyer around torpedoes or aiming an AC-130’s gun through a thermal camera.
Your aircraft get better as the campaign goes on, from the F-15E to the F-22, and coins from each mission buy upgrades in the Armory.

Your first jet: guns, missiles and a strike button.

Launches off the carrier deck mid-mission.

Stealth. Radar missiles can’t lock on, and two drones fly escort.

Stealth, three weapons bays, EW jamming and sensor fusion.

Put a GBU-57 on a weak point the size of a door.
