|The White Faction|
White Faction troops within Madler Crater
The White Faction are a terrorist group on Mars in the years after the fall of the Earth Defence Force in the Second Martian Revolution consisting to be remnant forces of the EDF. They go unnoticed for many years, hiding out in places like the Madler Crater on the edge of the Terraformer's range, masked by anomalies. They serve as the main antagonists of the movie. They are also solely responsible for turning the Red Faction and Marauders against each other after the raid on Alec Mason's family.
After the destruction of the E.D.S. Hydra , the remaining EDF forces are either hunted down, continue to fight, or go into hiding, as do Stroller's troops in order to make up for their losses until they were strong enough to resume fighting. After an outbreak of Influenza, members of the white faction resorted to kidnapping children from martian society to train as future White Faction soldiers, one of which is Lyra Mason, whose mother is killed by the soldiers abducting her, one of them being Stroller, who would try to become like a father figure to her.
The Red Faction launch a team led by Jake Mason to recover whatever they could before the Marauders reach the crash site. When they arrive there, he discovers that the Marauders have already arrived at the crash site, but many have been killed by a group of mysterious soldiers in white uniforms. Mason engages against one of them, and realises it might have been his long sister. Through this act of fate, Lyra Mason discovers her true origins and betrayed the white faction. Her lover Adam Hale assumes the role as the White Faction leader after Stroller is killed. It is revealed that their base is in fact a Severus-Class Dreadnought, which is now fully operational. Hale, full of zeal for his mentor and the EDF, leads his forces and his ship to the destroy the terraformers, seeing it as the only way to destroy all of their enemies. Alec Mason, finally making peace with himself after seeing that his daughter is alive, piloted a shuttle right into the bridge of the dreadnought, sacrificing himself and destroying the dreadnought and forcing the White Faction to retreat.
After their defeat and the remnants disappearing, their leader Adam Hale go on to join the Cultists, an offshoot of the Marauders, becoming their leader, and just like before, he would be defeated again by his sworn enemies.
- The White Faction may be a reference to the Tsarist White Army of revolutionary Russia. Both sought to maintain or return to the pre-revolutionary system of government, and both were primarily made up of military forces from the defeated side. Additionally, Red Faction seems to reference communist ideology and symbolism, which would draw parallels to the White Army's opposition in the Red Army.
