The latest review from Hyperdouraku is the the new outdoor survival game field called Battle Free Koga-Base which is located in Koga, Ibaraki Prefecture. It opened just last April 15 and according to Yas, it is a compact field of 45m x 25m, more fit for close quarter battles. It has a 30 people capacity though 10 vs 10 will be the most comfortable maximum configuration playing at this site.
