Purpose of the content:In 2007 I discovered several mods, Sven Coop being one of them. I absolutely loved it and played lots of hours, I even convinced colleagues to play with me. In 2008 I wanted to make my own campaign, but I didn't have a lot of mapping experience, and by 2009 I abandoned it. I now consider these maps obsolete from several points of view, but mostly because of their bad and random design. It was a good learning experience though. I don't know how "compilable" are the maps, but beware that I used mostly texture lighting.
There is one area that I have "refurbished", and compiled it for you. Just press everything you can press and watch the show.
Are CREDITS necessary? Well, I don't require them. Would be nice if you announced me what you used them for, for my own curiosity though! (you can PM me on TWHL).
