Up to 31% off tickets to a two-hour adventure game in the depths of the London Underground.

Why go?

Who knew the Holy Grail was squirrelled away somewhere on the London Underground system? Well, it’s time to suspend your disbelief, as the cup of Medieval legend is exactly what you’ll be hunting on this very cool-looking subterranean adventure game. Your treasure hunt kicks off at Green Park Tube where you’ll begin a gripping set of challenges that will require all of your team’s cunning, guile and aptitude if you're the guys to bring home the bacon. So bring your thinking caps, basically. You’ll have two hours to complete the tasks and return to base where the prizes (loads of official London Underground merchandise) will be awarded. But just to make sure you are kept on your toes, Some guy/girl called ‘Agent Alex’ will be lurking about, ready to disrupt your mission. The little rascal.
