I think/hope Prison is preety much ready for Beta testing, if anyone is interested please email me at firstname.lastname@example.org
or reply in this thread with your email, and I'll mail the pk3 to you. It's nearly 2 MEGS, so you'll have to have an email account that has that big a storage capacity I guess. I'll of course give the beta testers credit in the readme on the final release, and to sweeten the deal may put them into a thanks to bit at the end of the map (if I work out how to do that)
I've posted some more screenshots of the map...http://www.geocities.com/kengomaps/WIP.html
I'll put up the backstory on the site preety soon.
