The duo would enter the lower level. This was a underground walk way towards one of the subway metros, perhaps one of the safer places to be in. Relatively speaking: At least down here you won't freeze to death in a few seconds. But mutants, bandits, and starvation was still threats down here. As Donny and Cat walked through here they could sense the danger ahead. Though the headcrabs were few, they didn't attack either, which was the oddest thing. Mutants weren't like most animals that tend to only want to preserve their own life, with many of them suicidal attacking anyone or anything on the off chance of gaining sustenance. So the fact what few headcrabs the two saw didn't attack was something to worry about.

Eventually one would try to get the drop on Donny. It landed right on his head and started biting him, but fortunately his metal helmet prevented him from instantly getting his brains eaten. Instead he scraped the thing off with his axe, and once pinned to the ground shot it in the mouth and killed it instantly. But that was his first mistake. Despite being far away enough from the headcrab nest for the gunshot to go relatively unnoticed, there was a different threat down here that revealed itself nearly a foot away from Donny.

Bigger and tougher than the usual headcrab, and in facts eats them if possible. That would explain why there's so few down here and why they've been relatively peaceful, because the alternative was awakening this beast. Which Donny did.

[color=firebrick]"Shit fuck!"[/color] The creature snapped a claw at him which Donny barely avoided. He fired two shots into it's it's face but all the mutant had to do was lower it's body a little, and the bullets instead sunk into it's hard armored carapace. Granted thanks to using AP rounds the bullets did at least go through, but not instantly like Donny had hoped. The creature turned towards him while Donny tried to back away, still on his bad foot, but it seemed like the creature was at least distracted going after Donny instead of Cat. This could give her an opening to attack it while it's attention wasn't on her.
