[N] If you can still find it, there was one called Supermax (I think, I'm sure someone will know which one I'm talking about). It's really good, but I don't know if the writer is still around. I haven't even been around, stupid real world responsibilities...
I don't see him around unfortunately, but I believe his current regular name is Goliath. It used to be Camelopard. His stories are actually here on the forum if you use the search. They're very brutal stories, but very good.
