Big Sister is now SUPER ANGRY and someone's gonna pay
A straightforward mod that adds an additional hostile faction to the DMS series — Super Big Sister.
She won't bump her raid point cap from 10,000 to 20,000, nor will she send a horde of mechs to your doorstep at game start. Everything follows the same systems as any other normal hostile faction.
But there are a few twists.
Super Big Sister can draw from
the vast majority of DMS-series mechs for her raids, so the compositions always look wonderfully bizarre — every type of mech thrown into the mix. If you have certain expansion mods installed, some of the heavier units will show up as well.
(Images show a 20,000-point fodder-specialized raid, and a supremely furious Big Sister)

Super Big Sister fields her own
Dragoons, and they come well-equipped.
When the raiding faction is Super Big Sister and the raid points exceed 8,000, she will deploy one of her spare chassis to join the fight — be warned, it's "just" a backup body, but it can solo a Diabolus, and it will call in additional reinforcements on top of that.
Had enough of these chaotic super-raids?
Super Big Sister is
not a permanently hostile faction. You can raise relations through the usual means — gifts, releasing prisoners, and so on — eventually reaching neutrality or even an alliance.
However, the rate at which goodwill increases with Super Big Sister is only
20% of a normal faction's rate, meaning you'll need to send roughly five times the gifts to hit your target goodwill.
On the flip side, once you're allies, goodwill decay is also reduced to 20%.
Once allied, Super Big Sister's faction has a special perk: her military aid
always includes one of her spare chassis, and the size of the reinforcement force scales with your colony wealth.
Put simply, Super Big Sister's allied reinforcements are massive — generally enough to hold off an entire raid on their own.
Q&A
Q: CE?
A: Depends on whether your other DMS mods are CE-compatible.
Q: Can I add this mid-save?
A: Without the VEF framework, you cannot add new factions to an existing save.
Q: Why was this mod made?
A: DMS actually imposes strict limits on enemy variety and quantity (for example, soldiers are capped at 20 per raid, heavy mechs at 2-3, etc.), making the actual difficulty far lower than expected.
Put simply, you think you're going to face a massive army of mechs in an epic all-out brawl, but in reality the number of enemy mechs is extremely limited — they can't even keep up with you, let alone pose a threat.
This makes DMS a surprisingly easy and relaxing mod to play.
So now,
Super Big Sister is here to beat you up
