They altered their parts so they could each supplement each other in a loose formation and they communicated via quantum entanglement.
Their goal? To go help the Federation as the Rebellion doesn't have any interest in a swarm of Combat Drones forming their own AI.
Their name? Well, of course it had to be LEGION.

(Replaces Engi A)
The gimmick is that each drone is a separate room, so it means boarding operations will be scattered and it also means repairs are more difficult. I used the Repair Bomb from my earlier work, the Lanius Trail which does damage to enemy crew and repairs 2 points of system damage.
The ship also starts with only 2 Drone parts and a Drone Recovery Arm so initial deployment of drones is limited. But it comes with a Mini Beam for offense and an Ion Drone for shield removal. A Defense Drone deals with missile strikes that might set something on fire and cause hull breaches.
Lastly, there's an Artillery available but only in Captain's Edition or other mods that enable artillery. It's a Glaive Beam but it can only go through one layer of shield and it's slightly shorter.
P.S
If the game crashes from crew events and you lack crew, there is a solution here by meklozz, Player AI ships crew loss crash fix
