This is the most impressive shotgun I have ever seen. It looks in a way futuristic and in an other way traditional and I love this orientalic patterns. The shoot mechanism is also very cool. I especially like the red fire nozzles but I think the blue flashlight should also be red.
I really like the rotating cylinder concept for shotguns, and I kind of wish that a real-life manufacturer would do something similar (it's not difficult shotguns don't generate crazy pressures).
The ornate detail on this is great. Ergonomics look good too.
I would suggest a stocked version as well. Or maybe some add-on that can be applied to this shotgun to give it a stock. (yes I'm aware that the trend in game design is to stay away from stocked weapons because it makes animation way easier as clipping is much less of a concern)
boah. i'm usually not into such gun concepts (though i like guns in general xD), but this shotgun makes me jizz a little that thing really needs to be in a game ! i especially love those "pores" of the gun, which prevent overheating after a shot (i presume ^^), they look real sexy xD
