It looks like the Earth is set to be invaded again as D3 Publisher has opened a Japanese teaser site for Earth Defense Force 4. No additional details, such as a release date or which platforms it’ll be available on, were revealed by the site.
Developer Sandlot handled the first three numbered games in the series (of which, only the third was released in the US) before allowing Vicious Cycle to create last year’s spinoff title Earth Defense Force: Insect Armageddon, so it’s likely they’re developing Earth Defense Force 4 as well.
