The Aesir Fighter is an agile gunship used by the Ultor Corporation during the First Martian Revolution. It is capable of operating above the surface or in the cave systems below. For use against infantry it carried a forward mounted ULT-8CG 30mm Minigun, for heavier targets such as other gunships, it carries heat-seeking missiles fitted with ULT-AR Steeleye Tandem warheads.
There are only two occasions in the game where you can pilot the Aesir Fighter without using console commands to spawn it.
-In the cave systems while escorting Gryphon.
-Near the end of the game in the hanger just after Hendrix is killed and just before going through the hallway towards the final boss fight with Colonel Masako.
