Mo & Krill are Heroes in Deadlock. Fighting together, they are 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 to damage and Sand Blast to 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.

Background

See Mo & Krill/Lore for more story content.

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 of 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.
