So I'm a little mixed on the model but its mostly the odd position of its arms. I've looked at it quite abit. I think the reason the arms look the way they do, is because they might be piston/hydraulic arms for Slamming/Bashing which could be interesting. Also as others have pointed out there seem to be two sets of ranged weapons (guns) at waist level, and then theres the ram cod piece, so it could have Bulldoze.
Anybody else have any thoughts?
