From Press Release:
A totally new “EDF” project which takes place in a different world settings from the original “EARTH DEFENSE FORCE” series has started. Developed by YUKE’S Co., Ltd., with a theme song by Takashi Niigaki and creatures designed by Ryu Oyama for an “EDF” game that has never been seen before.
Welcome to “EARTH DEFENSE FORCE: IRON RAIN”. Set on planet Earth devastated by war, this new adventure joins the EDF as they continue to battle to save the world.
“Aggressor” is a generic name of the unknown visitor who came flying from the outer space in 2028. Other than the fact that they(including the “Hivecraft” which is considered to be the mother ship of the enemy)are currently attacking earth, their purposes and identities are unidentified. Human beings are suffering from the attacks of huge insects which were all scattered from the “Hivecraft”. In addition to the insect looking types, there exist heteromorphic creatures which look totally different from the creatures on earth and battle machines which represent their high technology level.
One of the military units lead by the EDF total commander in chief Renald Campbell. Without having a specific jurisdiction, the Blast unit undertakes particularly severe ground combats depending on the ongoing war situation. Only strong soldiers are gathered in the unit, but they all have very unique personalities.
Are they enemy or ally? Wait for more information on this unknown combat organization which differs from EDF!!
