I see pretty many handles on the fourth gun. Upper one is for carrying it around, ok; if the right one is to shoot with (I'm almost sure it is) then left one is to handle it since its weight is far beyond the right handle; what's the lower one for? And how does it all work, by the way?
well it suppose to be used like this [link] those handles - one of them was just for removing any ammo/reactor/cells from behind for recharging (?), whatever, couple others are just for comfortable shooting. However i think concept of 4th gun isn't best thing here It was some sorta research
My favorite one is the fourth gun, speaking from the perspective of someone who isn't a gun nut, and is frankly bored to tears by the millions of guns in game that i cannot tell apart from any gun from another game. The physics aspects of the gun be damned, who's to say is is not utilising future technology that we have yet to discover. Why would the weapon explode if it got shot at? Maybe it's non-explosive, maybe it's been engineered in such a way that it is not susceptable to internal combustion because it is designed to be carried upon the shoulders. It doesn't take much imagination to explain the weapons feasability. It's a very cool design, and i'd love to see something like that in a game. The ONLY crit i'd have is maybe the size of the thing. If it is to be carried upon the shoulders, i'd imagine it might be of a substantial size and weight that it requires the shoulder and back strength of a full grown soldier. Then again, the materials could allow for it to weigh quite a lot without being very big, but that could be reflected upon in the design, at the moment it looks fairly light.
