I was initially skeptical since I'm not usually a fan of Heavy Grenade Launchers, but the Hullabaloo is great. I got several with Voltshot and Chain Reaction. What a fantastic combo! Chain Reaction slays when you first fire then Voltshot takes over when you reload. It's incredibly lethal. I've never seen anything clear adds like this one. I can't decide if I like the blast radius masterwork or the reload one (to get the Voltshot effect faster) better. Either is still good. Anyway, this weapon definitely made the Guardian Games worth doing this year.
