Alliance Media Holdings Inc. announced the release of SHENZHEN I/O, the latest game developed by its recently acquired Zachtronics studio. The game is available on Steam for PC, Mac, and Linux. SHENZHEN I/O is an open-ended programming puzzle game that challenges players to build circuits using a variety of components. Inspired by real-world electronics engineering, SHENZHEN I/O is a continuation and evolution of the Zachtronics tradition of easy-to-learn but difficult-to-master engineering-themed games such as TIS-100, Infinifactory, and SpaceChem. SHENZHEN I/O was previously available on Steam's Early Access program.
