Not content with the upcoming Earth Defense Forces 3 Portable for PlayStation Vita, D3 Publisher has announced a fourth entry in the popular bug bashing series. The sequel – which is currently only confirmed for Japan – was revealed via a teaser website overnight.

While the title is unlikely to skip on a Western release, the publisher is keeping quiet about its plans for the time being. A spokesperson told Eurogamer.net: β€œThe game is being released by D3 Japan and they will be handling the launch of the title in Japan. If more information becomes available to me, I'll be sure to keep you posted.”
