Just did a progress report earlier today but then I started working on this and thought it'd be good to share.
This is the Steam-Powered Gatling Gun Glove.

Imagine having a gatling gun as your hand, and that's what this will be like when you grab it and put your hand (controller) inside.
The canisters on the bottom are water tanks that are used to create steam and make the gun start firing.
The things on the sides are train whistles.
When you start shooting, it'll spin up to speed and the whistles will blow as it unleashes it's firepower. It sounds like being plowed by a train because that's what it feels like.
