Check out this M-6 Carnifex Replica from Mass Effect 3 - This 8-Bit Life
Bill Doran has been making amazing prop recreations for quite some time now. His work is some of the best I’ve seen. He recently posted a build-log for his M-6 Carnifex replica from ME3 here. I would recommend you check it out if you’re into that sort of thing, and why wouldn’t you be? Weirdo. But to top of this awesome project he’s even posted a wubtastic video to show off the finished product. You can see that below.
