G.Rev bring us a trailer for their first STG on the 3DS. Kokuga, a title that was originally planned for development on Nintendo DS but has since jumped ship. The trailer shows off a stage select system and four player game sharing mode. Kokuga doesn't have an official release date yet but is expected to drop in Japan this summer. No word on a western release as of now.
I can see it now, some Japanese kids go crazy and build.... whatever that thing is. Go on a spree of massive destruction. Killing whatever those other things are.
