Luca Esposito, creator of the bestselling online video game, ECHO'S Revenge, can't wait to release the next and most ambitious version of his game monster- a real, artificially intelligent, 35-foot-tall extreme predator designed to engage gamers in a new gaming arena. But unknown to Luca and his AI developer, Prentice Petty, ECHO-7 has changed the rules of the game even before its release. As the monster completes its final testing cycle, something goes horribly wrong. The stealthy, shape-shifting super-intelligent predator has a plan of its own. This companion piece to ECHO's Revenge: The Ultimate Game is a primer and cautionary tale for young programmers who may one day create AI. Told from the perspective of the game designers and the AI boss itself, The Other Side presents the creators' perspective in a complex interaction of AI and the real world, echoing Mary Shelley's 19th century novel "Frankenstein" in our century of advanced computing and machine learning.
