Wing Force (Japan, prototype)

Wing Force is a two-player vertical scrolling shooter developed by A.I. under license from Atlus in 1993. This game remained a prototype and was never formally released; its existence was primarily documented through Japanese publications and promotional materials. Players control one of four distinct wing types as they navigate upwards, battling enemies and attempting to uncover the truth behind a shadowy conspiracy. Gameplay involves maneuvering your chosen wing fighter while firing upon waves of attacking forces. The game utilizes an 8-way joystick for movement and two buttons for action, allowing cooperative play between two individuals. Powering the experience are a Motorola 68000 main CPU alongside a Zilog Z80 processor, with sound provided by a Yamaha YM2151 chip. Despite its limited exposure, Wing Force represents an intriguing glimpse into Atlus’s development process during the early 1990s and showcases a classic vertical shooter design.
