What is weakest point of any mech? Stability and armour. While legged things can go everywhere, they are easily damaged as armor can't be too heavy. So what is easiest way to destroy incoming, menacing and ultimately powerful mech or walker? Just make it fall. Fallen mech loses all mobility, and until it gets up again is an easy target. If facing large walkers like AT-AT you can still shoot at joints - they can't be too heavily armored.
The Scorpicore is designed both to knock mechs out and destroy fragile joints. Armed by quadruple Thunder cannon (because hot plasma surrounding the bullet is making thunder-like storm), which technically is a Gauss gun, Scorpicore can deliver enormous pushing power on incredible ranges. It can also shoot smaller but deeply penetrating rounds, for which there is no armour.
"When the Scorpion shoots, you feel like being backstabbed by recoil. However I think that backstabbing is more comfortable." Felipe Aven, mercenary
Dude, anything named after a scorpion, that looks like a scorpion, and that is tough enough to take on mechs, gets my vote! Awesome creation. I would have made the "arms" just a wee bit longer, but I tend to be unrealistic. Love the guns!
