Earth Defense Force
Teams across the Red Faction Series
The Earth Defense Force (EDF) is one of the few elements that has appeared in every game in the Red Faction series, from Red Faction to Red Faction: Guerrilla.
Red Faction
In the first Red Faction game, the Red Faction rebelled against the Ultor Corporation and numerous mercenaries working for Masako. The game ended after a Red Faction guerrilla, Parker, called in the EDF to take control of Mars. The game ended with the EDF broadcast, "This facility is now under the command of the Earth Defence Force. Drop your weapons immediately. All armed personnel will be shot on sight." It is presumed the EDF went room to room shooting or arresting Ultor personnel. The EDF then reformed Ultor and had many of their executives placed under arrest.
Red Faction II
The EDF does not appear in Red Faction II, but in the story, they cooperated with the Red Faction to reform the Ultor Corporation. They also supplied the Red Faction with weapons and declared war on Chancellor Victor Sopot's government. It is known that they remained on Mars after Ultor's defeat.
Red Faction: Guerrilla
Over the course of the last fifty years, the Earth Defense Force had gone from being the liberators of Mars to being its new oppressors. Under the EDF's control, the people of Mars had no rights, and lived in complete misery. They were commonly beaten in the streets, and EDF officers were allowed to execute civilians without anything even remotely resembling due process.
It was this oppression that prompted a group of miners to revive the Red Faction. The resulting guerrilla warfare led to the EDF's eventual removal from the planet.
Though the EDF has notable leaders, such as General Roth and Admiral Kobel, such leaders are rarely seen in game. The EDF are a largely faceless and characterless enemy.
