The Chain Reaction skillshot is achieved by using the Flailgun's Charge Shot to slice two or more enemies in half. This is easiest to perform on Berserkers or Burnouts, as they usually line up when charging the player. It is also a good crowd control weapon because after slicing through multiple enemies, the flail can still be detonated.
- A chain reaction is when one event sets off another, and another and another and so on. This is a play on words due to it being a chain that cuts through more than one enemy.
