I was playing with Randy Random, on a ludicrous size map, and was at around year 3 or 4, and having survived some really weird shit.
So, in come this group of, i'm guessing, 60-70 pawns, from a friendly faction, all with serious weapons (i am using the weapons mod), they walk into my base, and loiter in the middle of it.
Then the other faction, tribals, decides to come say hi as well, and come with 150-200 of them (my pc is pretty beastly)
Turns out, they hate each others guts (you've guessed right!)
Since i can't do anything about it, i withdraw my peeps into my underground base (was in the middle of relocating when they arrived) they wreaked havoc on my base, and themselves, then, right as it was ending, and i was tending to the fires and bodies everywhere, one of my primary 3 colonists, turns to the pirate faction, i capture her, and in comes the cavalry, 15 guys, all in power armor, and mini guns, in drop pods, in the middle of the battlefield, they wipe/incapacitate my colonists, and decide to capture everyone they can, running off with their turncoat, and my remaining two colonists.
It was epic!
