"Bella..." Fabio was just beginning his usual patter when the first burst through the door.

His weapon came up, flicking to automatic fire he paused for a moment, then decided to aim a half dozen shots at the monstrosity's groin on the general principle that it had been human once and that out to be a sensitive spot, before flicking up to open up on it's face.  He backed up slowly as he did, ready to flee if it lumbered towards him, specifically.  Most things died with enough bullets, but in case it was one of the things that did not, Fabio was a decent runner, probably not fast enough to outrun the monstrosity, but he reasoned he would, at the very least, be capable of outrunning some of his team members (which was what really mattered in the end).
