Got my heroes doing stuff with a basic AI framework. They'll deal with threatening entities and POI features they can perceive, taking their own HP into account and spending time recovering if needed. And they can get into basic combat with the broodmother when they track her down, which they'll almost always win (although taking a lot of damage in the process). This is something else I'd like to expand on, with hero investigations into things like the Broodmother being more long-term with twists and turns the player can interfere with at the risk of losing their agent if discovered.
