The German USK has rated Damascus Gear: Operation Osaka HD Edition for PlayStation 4 and PS Vita.
The rating is likely for a localized version of Damascus Gear: Saikyo Exodus, which launched for PS Vita via the PlayStation Store in Japan in March 2017, and for PlayStation 4 as Damascus Gear: Saikyo Exodus HD Edition that August. A PC version was also planned for release via Steam in winter 2017, but has yet to launch.
Damascus Gear: Saikyo Exodus is a followup to Damascus Gear: Operation Tokyo, which is available now worldwide for PlayStation 4, PS Vita, and PC (Steam).
