Three years after the events of the first game, Aya Brea, now an FBI operative working in their clandestine Mitochondrial Investigation and Suppression Team (MIST), is dispatched to the Akropolis Tower shopping mall in Los Angeles to back up the LAPD SWAT team in response to reports of Neo-Mitochondrial Creatures (NMC) sightings. As Aya and her partner Rupert Broderick investigate the tower they discover a new form of NMC with the power to pass as human who were able to slaughter the first responders. As Aya works to exterminate the NMCs she discovers the building is wired to explode and encounters the psychopathic No. 9 who injures Rupert. Aya defeats No. 9 but barely escapes with Rupert when he triggers the detonators on the building.
