I have finished assembling my Leviathan Crusader dreadnought. I also bought a second gatling cannon arm for him. I'm hoping to run him as a rifleman dread. I know the Gatling cannons read more as assault cannons than Autocannons, but I don't plan on using this guy in games that much anyway--more of a show piece mini. I must admit I am pleasantly surprised at how much cooler this guy looks with two gun-arms. I have decided to find a good GW dreadnought engine for the back of this guy, as the shield-generator/smokestack-things on his back are bothering me more and more.
