I’ve hit it good with my bionic agent, details here-
Basically set myself up real pretty in a megastore, I have the more locations mod on so apartment towers and upped NPC spawn has given me access to a ton of manpower, I’m up to 8 NPC’s lurking in my base now. I have two more towers to recruit, and I’m building a faction camp directly next to my base. The apartment tower NPC’s are dumb as bricks so I’m going to put them all to work there, and keep the mutant and dynamic NPC’s in my megastore as my shooters.
Unfortunately bungled my attempt at colonizing the sewers. Failed to consider that C4 would blast open a crater from the streets down into the sewer, and I dropped a horde on myself after making my sewer car 
I’m surrounded by missile silo’s, my endgame is to destroy as much of the mega city as possible and build a fort in one of the multi-z level structures. Curious to see if turning most of it into craters eliminates horde spawning.
Hoping my next character when this one dies spawns nearby, I wish I could choose where I spawn- it’d be fun to treat this place as a base of operations for future characters.
