MIssion 2022 : desmoterion

Oct 8/9th 2022

What makes the event different?
Immersive!:  Yes, it is a running (or walking) event in London, but it is an immersive story-driven 'Experience'.

Briefings will periodically appear on the site, to provide background, and useful details.
On event day, you will become a member of RUN (Resistance underground Network). You will join an immereive registration event, encounter our cast, learn of missions to undertake, and engage with more cast members in the city throughout the night, to unravel the plot and complete the objectives.

Your mobile telephone will be a key asset in the event, to help you navigate Metropolis to your goals, and then reach the last transport before dawn...
