Lazer Arena Gwangalli is an indoor laser survival arena near Gwangalli in Busan, where sensor-detected laser tag games are played. Teams face off in a large space, chasing and being chased. Reservations are made through Naver Booking with a deposit, and the rest is paid on site; one game runs about 7 to 10 minutes. The first round alone takes a lot of stamina, so unlimited play is a strain.
