The planet Allium is facing a desperate situation due to global warming, resulting in the melting of polar ice caps and a significant decrease in habitable land. The remaining island chains are the only source of land, making it a valuable resource for survival. With a dwindling population, both the Forseti and Muspell civilizations are fighting over these islands.
Players take on the role of Hawk Winter, a Forseti cargo loader operator who has been conscripted due to his piloting skills. The game Battle Engine Aquila is a mechanized shooter that takes place in a larger battlefield, where the player's role is crucial to the war effort.
The gameplay consists of supporting and being supported by allied forces, fighting against naval, air, and ground forces in both modes of the battle engine. With its unique ability to switch between four-legged tank and combat jet modes, the Battle Engine Aquila offers a diverse range of experiences for players.
Battle Engine Aquila was released on February 7th, 2003, for the Xbox console.
