That's funny. You have pulled all the rippers to the hunter. Actually, the plan was for the Hunter to kill the Rippers together with you. The Hunter is now in the Ripper camp and then the demo goes even further :) You are not yet at the end!
(just my grain of sand here) really? In my case, when I found the rippers, the Hunter didn't show up at all until I was done with them, thought that's how things were suppossed to go...
