The Torpedo skillshot is achieved by killing an enemy with the Boneduster while sliding. It is best to wait until you are very close to the enemy to ensure a kill. Because you slide very quickly, enemies take longer to react, allowing you time to line up a shot.
One way to achieve massive and easy points with this skillshot is to 1) kick an enemy 2) begin sliding 3) immediately shoot them so they end up in an environmental hazard (such as a cactus). This will grant you the skillshots not only for the Torpedo, but Pump-Action and (in this case) Pricked as well. For an even better skillshot, fire a Flailgun grenade into the victim before kicking them to also get the Sadist skillshot as well!
- This skillshot is called Torpedo because torpedoes are fast, hard to counter and hit hard, just like Grayson when he slides.
