The AI's gotten kind of upset. Somewhere along the way it decided you puny humans need more interesting ways to lose (or win, if you're one of those people, but who are we to judge). Vengeance of the Machine offers new tools to the player (like Core Turret Controllers) and a new frontal-confrontation victory condition (Showdown Devices), but focuses on enhancing the already-incredible variety of your main opponent: the AI. The possibilities grow exponentially with the addition of the new "Dual Type AI" system (ever wonder what a single AI player would be like with Thief AND Speed-Racer? Find out!), AI Planetary Subcommanders, and Dire Guardians. They say the best stories revolve around an awesome villain, and this expansion takes AI War's villainy to new heights.
