The game opens on a bright stretch of East Colorado Boulevard where storefronts and mid-century façades line the sidewalk and the city seems to dare you to look closer. Players take the role of a Caltech janitor who stumbles into an abandoned lab; from Vroman’s Bookstore the first clue drops into your phone and the streets become stages.
