Though you do come across some Jackholes and Grunts they don't last long against the deadly AIDS attack, although the Grunts will, because they have Gruntiness. There are HUMANS in the level as well but you never get to fight(unless you use the Super Fart Skull.) because of the AIDs. Notice how the AIDS keep ruining the whole level, find the cure [Guess what! It's gruntiness]. The building is a maze filled with blood and enemies and an unusual number of Shotguns. You also find gold Sentinels and and the Big Daddies around that try to ruin Arbiter's killing frenzy. But this is all after the shield is brought down.
