Really, the title says it all. It would be nice if every major faction got their own special piece of technology, more powerful/different from the standard without being too unbalancing. Here is a sample list:
Outcasts: “Inferno” Anti-shield energy torpedo. “Cheetah” Thruster
Corsairs: “Tizona del cid” and “Colada del cid” pulse guns
Hessians: Cannonball MKII, Firestalker MKII, Sidewinder MKII (Missles with improved tracking and slightly more damage)
Kusari: Anti-shield ammo torpedo (For Fighters). Kusari’s answer to the Inferno. Projectile is more resilient to damage then starkillers/sunslayers, hopefully that'll make this more popular then other ammo torpedos.
Bretonia: Advanced Train CD, Smart ECM decoy. Improved support system capabilities to help ships survive.
Liberty: Liberty Universal Armor Upgrade IX. Very expensive, multiplies armor by 2.7x, uses 35 cargo. So the LN can better equip their ships.
Rheinland: Antimatter mine dropper. More powerful then a nuke, and slower.
Gallia: Class 10 faction guns (You just don’t find codenames in Gallia, these will be similarly priced with similar status)
Council: Superior Brigandine LF/HF shield. Stronger then other fighter shields, but keep in mind this shield type is weak against pulse weapons.
BHG: Identity Scanner (Better cargo scan range then Adv. Cargo Scanner, buff Battleship license/scanner to match)
These are all the biggest factions in Sirius. We got all the houses, the three most powerful pirate factions, and the BHG.
And no, you still cannot mount equipment from opposing factions. That and the tech chart prevents any one ship from getting all the best equipment.
