A new Earth Defense Force game has been announced. Titled Earth Defense Force Iron Rain, it is slated for a 2018 release in Japan. 

Earth Defense Force, the sci-fi action series known primarily for having big bugs and a terrible frame rate, is coming to the PC via Steam on July 18. The PC version is Earth Defense Force 4.1: The Shadow of New Despair and features an English dub for the first time. (And presumably a decent frame rate, too.)
