The High-Powered Microwave weapon (abbreviated as HPM) was a secret directed-energy weapon built by Leasath. It was made specifically for Leasath's superfighter Fenrir.[1]


As Diego Navarro was on the run from the advancing Aurelian forces, during the Aurelian War, he escaped to Archelon Fortress with the remaining prototypes of Fenrir. Aurelia performed a short island-hopping technique to quell Leasath forces, including eliminating the HPM shipment.[1]

The HPM's emitters were developed at Cobalt Cave, and after they were completed, they were being transported to Archelon Fortress via container ships. Gryphus Squadron was deployed to destroy these ships before they could escape the area. The squadron also destroyed warehouses filled with explosive chemicals. The weapon was ultimately destroyed and the HPM's threat was removed from the war.[2]

However, this allowed the Leasath Air Force's elite Alect Squadron to cross the Danern Straits and reach Archelon Fortress in order to pilot the Fenrir prototypes, thus making the aircraft even more of a threat to deal with.[2]

Alternative ending[]

Alternatively (and non-canonically), if you destroy the Alect Squadron before they reach the fortress, the HPM is instead delivered successfully to Archelon Fortress and subsequently used to combat the advancing Aurelian forces. The HPM is used to kill Aquila Squadron's leader, which forces the Aurelian formation to break formation. However, it remains ineffective agains Gryphus 1, who destroys all four Fenrirs, removing the threat of the HPM.


The HPM works under the principle of amplifying microwave resonance to ignite jet fuel. By having a ground-based emitter and an airborne emitter (in the form of Fenrir) both direct microwave beams in the direction of the target, an overlapping effect is created where the beams connect. The resonant amplification of the microwaves, combined with the large output from the ground-based emitter results in the target point of the HPM becoming visible to the naked eye in the form of an apparent energy sphere. The effect of the microwaves' amplification is almost immediately apparent, as the fuel temperature of the target aircraft will rise rapidly before igniting and destroying the aircraft.

The weapon was manufactured and created in Cobalt Cave, where satellites were placed to add a tracking capability to the HPM to make it easier to find and destroy aircraft. An electrical plant near Archelon Fortress powers the HPM (along with Fenrir's optical camouflage).[1]



  • If the player escapes a plasma sphere before their plane is destroyed, their engine's temperature begins to stabilize. However, this wouldn't be the case in real life; the electronics within the plane, along with the engine itself, would be structurally damaged by the sudden, intense heat. The plane would retain some internal damage after escaping the sphere.
