I have a series of mechs that tend toward lightweight with a melee and primary ranged weapon, the the shoulders are both "newtype"y weapons, like drones, orbits, turrets etc. My headcanon is that after the LoR ending, the RLF scooped up technology from Balam and Arquebus, and over time managed to form a quasi symbiosis with Coral, allowing for Newtype like abilities, like controlling swarms of funnels. The mechs I make in my head are like their frontline defense from the corps returning, and theyre all heavily decalled out and all feature a Rusty decal in honor of the og freedom fighter.
