Strolling down the modern streets of central Seoul, you suddenly find yourself back in the early 20th century.
You're on a mission to help liberate Korea from Japan's brutal occupation,
by locating hidden funds that are needed to establish a provisional government.
"The fate of our nation rests in your hands. Let us meet again under the brilliant skies of an independent Korea."
Using IoT sensors and augmented reality features, this smartphone treasure hunt game takes you back 100 years, to Korea's independence movement and the creation of its provisional government in April, 1919.
"You virtually participate in the making of the provisional government, by becoming the main character, rather than just learning about history as an observer."
With a confidential envelope in hand, and the game app on your phone, you set out to unlock each stage and solve the riddles.
Clues can be found in the nearby Deoksugung Palace, Seoul Anglican Cathedral and Gyeonggyojang -- which hosted the provisional government's final office.
Just a brief walk away in Gwanghwamun Square, you can further immerse yourself in Korea's independence movement, with the help of modern-day smart technologies.
Virtual reality goggles take you on a 360-degree tour of historically significant sites, such as memorials for independence activists Kim Gu and Ahn Chang-ho.
"The 360-degree view of the sites and the short clips and subtitles were great. It really hit home -- the importance of our provisional goverment."
Robots running on Korea's super-fast 5G wireless network, write out the "Declaration of Independence", and draw the flag of the provisional government.
"I like the writing in hand. The robots. So cool."
You can also throw your fists up and down in the air, chanting "manse" or "long live Korean independence", echoing the cries that filled the nation 100 years ago.
The experiential booths in Gwanghwamun will run until next weekend, but you can enjoy the treasure hunt until mid-June.
