Today the Gundam Base Tokyo, the largest Gundam store in the world and home to the life-sized Gundam, held a livestream. While its main purpose was to show the Hong Kong entries for the Gunpla Builders World Cup, a big surprise was revealed. What was shown is clearly in the proof of concept stage, but they showed off a process that takes an assembled model kit and converts it into a playable game character.
You can catch the process below at the 37:50 mark, which begins with showing off the custom model.
