Another gun concept! Yay!
The idea for this was to make something for the Mass Effect Universe.
This is meant to be a gun for survival purposes: So most of its build is based on being used as tools. The back's made of a material to absorb shock from the hammer and axe, so the gun is just a heavy pistol integrated into the whole tool. There's a mass effect field generator in the hammer end to make it easier to wield, probably adjustable from an Omni-tool. I also see the gun being based more on Mass Effect 1 technology than the rest of the series. It wouldn't be useful in a survival scenario if you need a constant supply of thermal clips.
Mass effect is owned by Bioware, while this design is owned by me.
If anybody has any suggestions for another series I could make a gun for, drop it in the comments.
