Your sightseeing plans just got suspicious. Your mission in Plymouth starts at Burton Park. In plain terms: a team spy adventure on foot, with the missions on your phones. Along the way, Plymouth shows you a taste of its culture and some green space. The mission is the excuse. The real game is figuring out which of your teammates has been lying since the first stop. Some missions need a sharp eye, some need a little nerve, and some need everyone talking at once. No puzzle skills required, just a sense of humor. There may be a double agent on your team. There may not. No app, no guide, no headset. About 2.5 hours and 2.4 km, with 4 stops that stay secret until you earn them. Afterwards, your official report will say: sightseeing. The photos will say otherwise. Who it's for: friends, couples and families with teens; and private groups, from bachelor and bachelorette parties to work teams and active over-55s. Book a private game for 1 to 8 players on a date you choose; a team of one works too. Teams are up to 8 players. A bigger booking plays as several teams of up to 8, formed at the meeting point.
