I went back into Maya and played around a little bit more. I like this design more than the last as the shapes have more of a flow to them. This is a handheld version unlike the last shoulder mounted. The cut in the back is where the weapon actually absorbs power from the using Rike alien's mechanical suit. This allows for no reloads and short periods of over heating. To keep the cool down time to a minimum the heat sinks up front help cool it down faster while the vent clip on the bottom releases spent gases to keep from a critical failure and combustion.
