Hey, is their any grey renders in the single player mode? and if so, do they do what they really do? do you find a grey render protecting an area, or another creature? Thats one of the habits of the grey render and I want to know if it was put into single player.

AFAIK, there's no difference between single and multiplayer modes, so there's no reason for the monster not to be there. I haven't seen it yet though. ;)
