I was able to get the anarchs ending without doing their quests

[NightMistress]

I was going to originally go with no alliance since I thought you couldn't be an anarch without helping them, but I did want to side with the anarchs so when I saw that option I took it. I thought that one needed to have completed the A Plague For the Angels, Attention Whore, and Fun With Pestilence quests in order to recieve the option for that ending, but I guess not necessarily. I think I was pretty nasty to Damsel at first too. I was nice to Nines up in "wolf country" though so maybe that had something to do with it?

I don't think that I had the option to side with Ming Xiao or the Cammy. I think I'll go back and play out my other two options as well.
