Battle Engine Aquila is an action-shooter game for Sony’s PlayStation 2 console. In the game, players control a high-powered mech named Aquila, packed with diverse weapons and is capable of transforming between a walking tank and a jet aircraft. The setting is a post-apocalyptic world, where rising sea levels have driven humanity to war for the remaining dry land. Battles are grand in scale, involving dozens of friendly and enemy units at once, which adds a level of strategy beyond typical shoot-em-up games.
