Third Spaces was tasked with building Hinterland Uncharted a new mobile game and festival experience for guests of the 2025 festival. In less than 90 days, we built a fully functional scavenger-hunt mobile game and an on-site activation. Attendees were invited to engage in over 25 experiences at the festival for the chance to win tickets, merch and other prizes. Featuring animatronic flowers, glowing mushrooms and natural materials incorporated from the surrounding environment, the immersive 'Secret Garden' activation was a popular attraction, prompting shareable content on socials.
