Purchase a Mod in every tier for all upgradable items in the Equipment Terminal for one character.
Purchase a Mod in every tier for all upgradable items on one character - i.e. fully unlock every weapon/tool/armour mod slot for a single dwarf at the Equipment Terminal. This is a big credit-and-resource sink: keep mining and completing missions to afford all the upgrades for one class. Pick your favourite dwarf and kit them out completely.
