She altered some players' minds, and gave them the ability to transform into a form more suited for battle, and forced them to subsist on sentient flesh. As you can imagine, it was a bit familiar. But it seems that of the people changed, only Orion managed to resist completely, though some other teams turned on their fellow 'wolves' rather than kill innocents.

Hollow killed him, out of mercy, in a way; another team had determined that he would die and her knife was kinder than their teeth. At the time, though, I was pretty angry.
