>>43354057To flesh out further, I think they would belong to a group of hardy survivors trying to rebuild Rapture, not escape it.
They've found The Thinker and are using it as their ace in the hole, using a lot of automated systems to make up for not having too much ADAM.
The Lancers are their primary soldiers, lots of technology making up for limited ADAM enhancements, mostly gene tonics and strength enhancement and such with a couple specific plasmids, one or two to each individual.
Tenenbaum seems to have figured out eventually how to use ADAM safely considering that she turns Subject Sigma human again and Jack was spliced to the gills but seems to live a long and healthy life.
Maybe she's on board here, working to make sure that the Rapture nightmare never happens again, because the only way to really be sure is to take the city over completely and make ADAM safe, otherwise people are always going to be springing up dangerous cults or surface people will try to find the city ignorant of the dangers.
They don't have too much ADAM because they don't use little sisters, getting by on a few isolated stockpiles and setting up a kind of fishery for the sea slugs that produce them, as well as extracting it from dead splicers.
Not as efficient, but reliable and not fueled by horrors.
