Battle Engine Aquila is a 2003 video game for the Xbox, PlayStation 2 and Microsoft Windows in which you pilot the Battle Engine for the Forseti military in their wars against the Muspell to decide who will rule what's left of the world. Battle Engine Aquila received little attention from the public despite overall good reviews from critics.
The ice caps on the planet Allium have melted due to constant greenhouse effects. As a result the most planet surface has become underwater. Only 13 islands scattered across the surface remain. Thus only two civilizations remained of Allium's human-like inhabitants: the peaceful and technological Forsetti and the aggressive Muspell. Both civilizations are at the brink of war with each other in a battle over the remaining landmasses.
The player assumes the role of Hawk Winter, a Forseti dockworker. He is also a dock racer where he races on his loader. After one of the races Tatiana Kiralova, Hawk's girlfriend and an overseer of the Aquila program, persuades colonel Chuck Kramer, the leader of the Forseti Air Force, to secretly assign Hawk to piloting the Battle Engine.
The Battle Engine has two modes of operation: "Jet mode" allows the Battle Engine to fly for a limited time, "Walker mode" transforms the Battle Engine into a mech-like walking tank. When the Battle Engine is in Walker Mode, its weapons are considerably stronger than when it is in Jet Mode, it is tougher but much slower.
