Batman Arkham Knight: 10 Side Missions Rocksteady Should've Included

4. Ratcatcher - Extermination

The Villain Otis Flannegan is a relatively unknown Batman rogue who has the ability to control and communicate with rats. With a power-set like that, you€™d think he€™d rule grubby Gotham with an iron fist, but he€™s been in Blackgate more often than not, using his furry friends as couriers for other villains. The Mission Finding and analysing the mutilated body of the KGBeast, Batman discovers he€™s been eaten alive by rats. Placing a tracking device on a nearby rat, you follow it into the sewers. Inside, you analyse two more bodies. City officials who had been involved in Flannegan€™s sentencing (a nod towards his debut story). Ratcatcher tells you his mistreatment from other inmates shows him that villains are the true infestation. Otis summons a wave of rats and you must escape, eventually diving into a vent. Rats pour in and one wrong move means the Bat is rat scat.
Lucius Fox sends you a sonar device to keep the rats at bay. You return to the sewers and the rats part for you like the Red Sea. Flannagan has captured Crazy Quilt and Humpty Dumpty. You use batarangs to untie them so that they can deal with the rats while you take on Ratcatcher. While fighting Flannegan, you must use the sonar device when the rats close in or attack the others. Don't fret, you can do a double takedown with each. Eventually, the device breaks and the two villains are eaten. Before the rats swarm you, you KO Flannagan. The rats instantly stop, silently, and you carry him away.
