Thanks for the links Brusilov, I have always wanted to play the IB mod but you have just reminded me of why I never have!
It's the most frustrating forum page I have had the misfortune to come across. I can never find a link to the mod. There are a tonne of sub-mod links at the top that have no obvious download link page and neither is there on the main page. It's like the mod's makers don't want people to play the mod until they have had a tedious time consuming search for their most important link. It should be in the viewer's face, lit up with christmas tree lights, bolded, underlined everything to grab your attention but their's, sadly not.
