As requested by Sword_Of_Geddon. This is a modders resource which contains the Stealth Destroyer, Destroyer, and Deliverator's Leviathan recolored grey with a modified Attack animation to the use the laser effect from Final Frontier.
I had to flip the Effect nodes because they were firing backwards, so any other unit that uses these animations will have to have the same done. Here are their artdefs for ease of use.
