Snarling sounds are heard from above as I assume the creature regenerate, starfish-style. "I sliced that thing up as much as I could. I doubt conventional weaponry stops them." Reaching the bottom, we find another sub-basement, yet this one appears to be a literally upside-down version of our Mall. I float up to see the shops, the products all neatly stack on the ceiling.
Then I see whatever the hell is hanging like a goddamn bat from the ceiling.
