Amazing_Goob (Nope, 'liquid electricity' is to be taken literally. The maniacs in the future found a way to compress electrons into liquid form. Yes, those energy cores are rather unstable and highly volatile.
The drones are armed btw, so you might aswell have it try to blow something up using its antimatter missiles and have them hit itself instead or break the plasma charger for it's plasma beams. Or detonate the HE-FTL-projectiles in their mags.
And how many c did your
Amazing_Goob chunk of metal, small enough and fast enough to get through it's shield
have? 'Cause anti-FTL particle shields would never let a simple chunk of debris through.
Guess one could argue they haven't been checked for ages and the shield got damaged during storage tho.
It also has an odd internal thrust system using a forcefield to move the entire thing and military grade energy-reflective paint above quadruple layered armor, having neutronium armor plates, a nanomesh layer, the future version of an extremely hardened synthetic carbon steel and some odd alloy including too many things to name.
Yet again, you're free to ignore all the OP-ness I had to bring due to a lack of standart tech characters/entities as long as it makes at least some sense. My best tip would be to justify things with internal damages, most external attacks should theoretically bounce off the armor and shields.)
Beeing severed from the rest of the drones and its base, 2-0s ai initiates the extermination protocol, deactivating the forcefield used to replace the damaged sections and overcharging all systems. The combined explosions of the antimatter missiles, the FTL-cannon magazines, the plasma overchargers and the drones core vaporise the entire frame and anything in the surrounding space.
Drones 0-1 to 1-8 take position around the entire planet and start mapping every piece of debris and the planet below, relaying the data back to their ship to have it calculate the spot of the next opening, while 1-9 activates its weapon system and tries to use the hole 2-0 caused and its own weaponry to make it through the debris. However, it stays way more careful than 2-0 was and only starts moving when certain it will reach the other side.
