Splinter Group (enemies)

The Splinter Group is a clan of Rats living in the sewer side–area within Bloodshot Stronghold whom Patricia Tannis instructs the player to murder during the mission Splinter Group. The group consists of Dan, Lee, Mick and Ralph. After pizza is left in the middle of their room to lure them into the open, they initially fight the player one–by–one, disappearing once their health meters are half depleted and then reappearing together after each has had their initial "turn", whereupon they can be killed. They all wield melee weapons, have shell–like objects strapped to their backs, and are apparently acquainted with a woman named June. Killing them in a specific order, that in which they initially appear, is the solution to the challenge Cut 'Em No Slack.

The Splinter Group is secretly led by Flinter, who has to be lured out via a secret puzzle in the room accessed after killing the main group and is significantly stronger than any of the main four individually are.

The Splinter Group is an extremely blatant parody of the Teenage Mutant Ninja Turtles, with literally every detail about them referencing the franchise.
