About this game

COUNTERSIGN is a deduction game played under a ticking clock, watching suspects move through a city labyrinth through a rooftop telescope. Witness reports stream in but some are deliberately falsified, so you must cross-reference them to work out the spy's codename and type it before the intercept window closes. Three wrong calls and your cover is blown.
