Android (prototype, early build)
Android (prototype, early build) is an unreleased arcade action game developed by Centuri in 1982, originally planned as the studio’s answer to popular sci-fi arcade hits of the era like *Galaga* and *Xevious*. Never launched to retail due to internal restructuring at Centuri in late 1982, this early development build was recovered from a set of abandoned studio archive tapes by retro game preservationists in 2017, and has since become a highly sought-after rarity for arcade collectors and retro gaming fans. In this prototype, players take control of a bipedal Android mech tasked with defending Earth’s orbital stations from waves of invading alien robotic forces. The early build features 5 playable wave stages, placeholder sprite art, temporary 8-bit sound effects, and a number of unfinished mechanics that were set to be expanded in the final commercial release, including a scrapped final boss fight against the alien mothership and a planned upgrade system for the player’s mech.
