one of my all time fave mech designs, I don't think I'll be coloring it anytime soon, but it's high on my list.
the original name was gonna be the THOR unit with the MJOLNIR assault pack, but how many mechas are already called thor, compared to the foldable/transforming battleship SKIDBLADNIR
The SKidbladnir uses rail cannons in order to generate a huge magnitude of energy per bullet, as a result, the unit has to house a large energy unit for ammunition and generating power. However, it has powerful propulsion systems on the pack in order to enable significant agility and movement, however this drains energy as well and can leave the unit defenseless, however using experimental mass conversion and tech collapsing technology, the assault pack can be minimized to a smaller, more manageable form for agility and maneuverability.
Aside from the cannons, the unit is also equipped with a rail pistol that combines pressurized vacuums to accumulate force per shot, as well as a high voltage stun club/electronic pulse gun
the assault pack comes with its own propulsion system that gets rid of the majority of the weight, the suits own strength enhancement properties and weight loss system takes care of the rest of the problem
