Xor World (Modular System, prototype, set 1)

Xor World is a cooperative puzzle game for two players released by Gaelco in 1990. This prototype appears to be part of a larger, unreleased modular system from the manufacturer. Players work together on a screen displaying shifting patterns and logical challenges; successful gameplay requires coordinated action to manipulate these elements. The exact nature of the puzzles or goal remains undocumented, classifying this title as an intriguing glimpse into a potentially abandoned game concept.
