Changes

Killing a Leviathan is impossible without a group of at least four pilots with their pick of equipment. Outfit your Ragnaroks with the highest damage ordinance in the game. Park your ships at 5000m, which is just far enough to be out of radar range. Make sure you have no target selected. Have one player count down, and lock your turbo on at the same time. When you reach 3000m (you can tell by watching your sector list), begin firing. Do not deactivate your turbo until the shield has fallen, or you have failed and need to try again. Note: do not target the Levi with guided missiles; these will fly faster if left unguided. Your goal is to deal the maximum possible damage in the minimum possible amount of time. More players obviously makes this task easier. With enough players, a group could theoretically use energy weapons, though the defensive turrets of the Leviathan would need to be planned around.
