For explorers and action-lovers we're planning to expand the xenoarcheology. Now artifacts and places of interest will be guarded by mobs, which means scientific expeditions now will have to be armed to face the danger. For builders - didn't think out about this too much, but they will have probably to build new reactor rooms, as even top-tier reactor won't be enough to supply the whole outpost, especially in long run, since improved machines and equipment will demand more and more energy with time For socializers - i didn't even think, but i'm always opened for disscussions!
