The group heads further down into the hive, and is ambushed by some mutated people, followed by some mutated rats.
The rats and people are all controlled by some kind of heretical umbilical cord. They all have hooks on them, which they try to hook the party with, and drag them along somewhere. The party had to fight just to stay upright and all together, though the rats tried to drag them into air ducts where they could not fit anyway.
There seemed to be a neverending stream of creatures, they would have run out of ammo before destroying them all. They managed to come up with a way to grab hold of a broken umbilical, and use blind grenades to keep from getting hooked by any creatures they pass. The plan succeeded, and they were able to get pulled along toward a giant gibbering mass of flesh, seemingly made of different people.
