Publisher D3 unveiled a new teaser website for Earth Defense Force 4. Not much else is known about the title, including what platforms it'll launch on.

So far, there's no indication of a release in North America or Europe or what developer is handling the project. U.S. based Vicious Cycle developed Earth Defense Force: Insect Armageddon, the last title to be released in North America.

D3 is also prepping Earth Defense Forces 3 Portable for PlayStation Vita this September in Japan.
