I've got some decent ideas for some empire specific implants/equipment.
VS-Implant: Modified personal shield implant that makes beam weapon fire heal you but take twice as much damage from normal gunfire. Equip: grappling hook to scale walls (but slowly, so using a MAX to jump is still better and the scaler is still vulnerable).
NC-Equip: Grenades with a secondary fire that breaks them into four pieces in the air that spread out in different directions, each with a quarter of the power of a normal grenade (cluster bomb). Implant: Personal shield that extends around vehicles but consumes twice as much stamina.
TR-Equip: Deployable turrets with 2x as many barrels for 2x RoF, but also 2x ammo burn and half the ammo. Implant: recoil reducer that makes cone of fire smaller (so that bursts of fire can be longer).
Yeah, some of them are outright ridiculous, but at least they fit the themes.
TR-Offense
NC-Defense
VS-Strategic movement
