It hits Japan later this month
Later this month in Japan, Damascus Gear: Tokyo War Begins will launch on the PlayStation Vita. It's from Arc System Works, developer of Guilty Gear, amongst other modern classic gems.
Based on the trailer it looks like a hack and slash game with a visual style that's strikingly similar to the Front Mission series. Evidently you'll be able to collect loot just like any standard ARPG and customize your mechs. It'll launch on Christmas Day in Japan for 1,800 Yen, and I really hope it gets localized.
