Zone of the Enders: The Fist (known as Z.O.E. 2173: Testament in Japan) is a compelling tactical RPG for the Game Boy Advance. Set in the Z.O.E. universe, the game tells an original story following Cage Midwinter, a young man who finds himself piloting the powerful Orbital Frame, Pharsti. Unlike the high-speed action of the console versions, The Fist uses a grid-based tactical system combined with an innovative 'IAS' (Internal Action System) for real-time aiming during combat. The game features branching storylines, multiple endings, and high-quality character portraits, making it a deep and immersive mecha experience on a handheld.
