Mo & Krill are together a disruptive and mobile pair that can burrow around the battlefield and leave their enemies in ruins. Beginning encounters with Burrow can let Mo & Krill pop out on unsuspecting enemies, attacking them with Scorn and Sand blast to damage and disarm them. With the support of their team, they can Combo one targeted enemy to pin their target in place while the rest of their allies unleash their attacks.

Members of The Tunnel Rats, Mo & Krill are smugglers and illicit traders who make the underground of New York their home. Rival gangs that try to exploit these tunnel systems for their own gain will rapidly discover how protective and deadly this pair of smugglers can be.

Mo and Krill are members of The Tunnel Rats, a group that help facilitate illicit trade and commerce between the boroughs thanks to a network of underground tunnels. But while most denizens the New York underworld respect the work The Rats do, every once in a while a gang tries to exploit the tunnel system for personal vendettas...that’s when Mo and Krill step in and remind the city what happens to those who disrespect their hospitality.
