Oh right, weapons-wise, is there melee or just ranged weapons?

There's melee and ranged. The scope of melee ranges from "this is a last ditch effort" to having mechs specifically designed for it and all auxiliary ranged weapons/systems support their ability to cut things in half.

For melee, beamswords, chainswords, massive hunks of metal, energy emitting blades, etc are all viable.
