Each faction has five unique Faction Kills that are different from one another, though they share the same button inputs. The player is given access to two Faction Kills upon joining a faction, and can unlock two more by ranking up in that faction, and a final one by winning the Faction War with said faction.
A Faction Kill must be performed from at least a jump distance away from the opponent.

- Dirty Bomb: A grenade-like bomb lands at the opponent's feet, beeping for a moment before exploding the victim into bloody giblets.
- Chemical Bomb: A bomb similar to the above detonates immediately, expelling a green gas that wraps itself around the opponent's head, reducing it to a bloody skull. The opponent falls face down with the gas emitting from their skull.
