Cave, best known for its bullet hell shooters, unveiled its 2011 game line-up in Tokyo's Akihabara neighborhood this Monday. The company unveiled the iOS version of their Xbox 360 cult hit, DeathSmiles, alongside the 360 version of the arcade vertical shooter Red Katana. Although Cave has never region locked their 360 titles before, and has encouraged fans to import them when not available in their home countries, Red Katana shin will be region locked. It's likely that the move is an attempt to attract publishers outside of Japan. The shooter genre is so niche, that a region free version could cannibalize future foreign sales.
