I am wanting to make some kind of heavy gun for my main weapon, but I keep running into walls. I was thinking of a multi barrel gatling type gun like what the clone troppers used in Episode 3, but anything I find to mod looks too earthly or cartoony (especialy nerf). Then I thought some kind of grenade/rocket/missle launcher thing, but I can't find anything with a big barrel that looks like it shoots more than one round. I don't think a star wars era grenade gun would be a one shot and done weapon.
Anybody have any ideas? I have also been toying with the idea of adding blast plates to the shoulder area if I go with a missle type launcher, but I don't want to look like I am getting ready to joust...
