The First Martian Revolution, or as the EDF have referred to it, the Ultor Uprising, is a conflict that occurs on Mars in 2075, where a miner riot against the oppressive Ultor Corporation develops into a fully fledged revolution. The miners form the Red Faction, a rag-tag militia organisation lead by the mysterious miner with the pseudonym 'Eos'. Their goal is to overthrow Ultor, but their soldiers are ill-equipped, untrained and badly-matched against the Ultor security forces in most engagements.
