Reef Runner is a mini-submersible operated by Bobby of Ocean Floor Mining Corporation in 2017 CE. It features a truck bed aft-ward with interlocking bars to secure goods during transit.
After being sighted prospecting outside of Ocean Floor's claim, Reef Runner is pursued to its home base by two hornets, thus leading to the escalation of the Livingston Trench Incident (DSV: "To Be or Not to Be").
