I think the Engine STD255 should be a standard for the Roughnecks as it runs as common Heavy speed of almost 64 kph Can get real hot over time Ammo shots for both Lbx and Srm are at almost 20. Quickdrop games usually over before you use all of them ammo. Jackhammer 6A (1xLB10-X,4xsrm6+Art STD255) if you see someone runs this but runs at a highspeed, it will be an XL engine, shoot the side torso.
As opposed to the srms6+artermis Variants This one sacrificed pin-point damage for speed and a little bit more ammo for the srms Its still focus on the 20 alpha shots and can run a little hot after 3 to 4 volleys.
