Earth Defense Force 2025, known in Japan as Chikyû Boueigun 4 (地球防衛軍４ (Chikyû Boueigun 4)) is a third-person shooter developed by Sandlot and published by D3 Publisher for the Xbox 360 and PlayStation 3. It was released on July 4, 2013 in Japan and on February 18, 2014 in North America.
The Earth Defense Force, a unified multinational military sponsored by nearly every country, is founded after detecting an impending alien visit in case the aliens prove to be hostile. In the year 2017, that proved to be true and the EDF fought against the Ravagers, an alien race that attacked Earth with giant insect-like creatures, UFOs, robots and gigantic, 120-foot-tall lizard-like creatures. Eight years after defeating the last Ravager in Arizona, they attack again with new creatures, evolved from their underground nest. Among them is the Retiarius, a spider-like creature which makes gigantic spiderwebs, and giant wasps. In the year 2025, the EDF must protect the Earth again from the alien invaders.
