well, for an uber monster they handled it fairly well.
Frontal assault didnt work well so they wore him down by keeping him from feeding, wouldnt actually attack but do all they can to stop it from getting a meal, and damaging some of its cyberware. essence drained so fast that it had to dump a portion of its parts, then went after it when it was weak (well, compaired to how it was before)
They handled it fairly well, though to keep it from getting essnce they split into groups and some figured "acceptable losses" when it was just bout to put its fangs into someone.
It was strong, but it made them work together, plan, coordinate, and something i like to see THINK, but hey, im just weird like that i guess.
