Trust no one in Trenton. Especially not the teammate who keeps volunteering for lookout duty. In plain terms: a team spy adventure on foot, with the missions on your phones. It is the rare activity where you are supposed to take selfies, point at buildings and whisper to each other in public. It is all part of the job. 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 humour. There may or may not be a double agent on your team. No app, no guide, no headset. About 2.5 hours and 1.7 km, with 4 stops that stay secret until you earn them. You leave with the photos and some pointed questions for whoever was so very keen to keep watch. Who it's for: friends, couples and families with teens; and private groups, from bachelor and hen nights 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. Bigger groups play as several private teams.
