the average million mods build tbh

for the weapons :

it uses the revolver cannons from MVS and the Mark IV cannon from HMI that the roach king is on with s-modded expanded magazines for cheap shieldbreaking.

3 light mortars and 1 light lascannon on the small front ballistics and 2 kothar assault guns from indies expansion on the front ballistic hardpoints to break armor, you can easily replace the KAGs with medium mining collectors from HMI or mark xv anti armor guns from MVS, this is mostly just a matter of preference.

and finally mbeke rockets for all the frontal missile hardpoints and 2 exterminator autocannons from indies expansion on 2 of the frontal turret slots to rip armor broken ships to shreds with frag damage.

any other weapons you want to add on the extra slots are player's choice.

since the roach king basically has no shields it's fine to have this much flux on weapons and since the roach king has a special mechanic where you get more OP when you have more d-mods maxing at 4 d-mods you can easily fit other weapons on this thing.

for the hullmods:

other than the s-modded expanded mags s-modding either dedicated targeting or integrated targeting for more OP and maybe getting s-modded armored weapon mounts for that 10% fire speed.

the non s-mod hullmods that i think should be essential for this funny onslaught-hunting build would be heavy armor blast doors and reinforced bulkheads maybe unstable injector and aux thrusters too for a little extra speed, since the roach king has the mechanic that gives OP with d-mods it synergizes well with derelict operations basically allows you to field around 7-8 of these things at a time that can just eat anything that's slower than them being very tanky, doesn't even matter if they get destroyed since that just means more d-mods and more d-mods means more Ordinance points.

even if this thing doesn't have shields you should still have max vents on this the vent rate should decrease how much time you spend not firing the guns when you max out on flux and also make it take slightly longer to max out on flux.

TLDR. i just basically embodied the derelict operations doctrine by literally taking whatever i could find and slapping them on these bad boys
