The world of SYNTHROME was once governed by the Builders, who constructed the SynthRide as emergency infrastructure for times of war and instability. The Seven SYNs ended all of that by taking over the world entirely. You begin in the uncorrupted server, then move outward into the chaos of the hub and beyond — through vast and varied environments across more than eighteen full levels — toward SYN City. The mission is singular: liberate SYNTHROME from the SYNs. Mysterious logs and cues will guide you when the path ahead is unclear.
