Tag-Team · Initiator · Burrower
Lore
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.
