Basically he did it with beam and pulse lasers for no ammo requirement and then just tagged NPCs fighting cap ships. If the ship dies within 10 seconds of the tag, it counts as a kill, which is how he is able to achieve 2.5 kills per minute.
8200+ kills! This could take a while.
apparently not in open play though (last page)
He is claiming it was in Open Play, where does it say he isn't?
One of the mods mentioned it
