There are probably Sentinels loose in the city. I just got away from one, and they never travel alone. But without Sentinel Services here I have no idea who's controlling them or if they're only still targeting mutants or what they'll do once they capture someone.
They're small, durable, fast, adaptable, sort of spider-like like machines with a rotating red eye. They can crawl up walls and ceilings, and if they get a grip on you, even people with enhanced strength can have trouble escaping.
