Description
The Zodiac Killer terrorized an entire generation, taunted the police with coded letters, and disappeared without a trace. Decades later, a brilliant copycat has broken into a police evidence vault, stolen the original 1969 case files, and targeted a brand-new list of victims in Texas. He has openly dared the city's task force to stop him—and now it is up to you to take the case.

Fully guided by the Questo app on your smartphone, you'll track the killer across 14 urban locations, analyzing physical murals, real monuments, and old inscriptions to gather evidence.
