Indignate, sorry I missed you last night -- I fired up Dark Souls when you said nobody was around and you were doing beast -- by the time I saw your message I had stopped playing anything and was reading some stuff online before bed, definitely did not have enough gas in the tank for 11 tough rounds of horde.
That said, did you guys manage it? If you did, any chance you'd be willing to do it again? If not, when do you want to try, later tonight?
