What if location-based entertainment could provide new insight into the inconceivable realities of past wars? Through installations at the Tribeca Film Festival and in Austin, TX, 'War Remains' transported hundreds of people directly to the front lines of the First World War. Using floor rumblers, wind effects and special haptics, along with a touchable physical set and the narration of Hardcore History's Dan Carlin, 'War Remains' allows people to experience one of the most nightmarish wars in history like never before. This session shares key lessons learned for designing an LBE during the year-long production of 'War Remains', created by MWM Immersive in collaboration with Dan Carlin, Flight School Studio, and Skywalker Sound. It is a deep dive into how the speakers resolved design, audio, and technical challenges while maintaining a high level of historical accuracy, all within 650 square ft.
