From the publisher's website: War In Russia - Matrix Edition allows you to play up until July 1945, fighting for four years over the new improved map. Arnaud Bouis and his dedicated team have once again improved upon Gary Grigsby classic wargame War In Russia. Arnaud Bouis and team began this project back in May 2000, its aim being to fix the bugs to one of our favorite computer wargames and has done a great job. Please note that the version available here at Matrix Games is also the same version available at Arnaud Bouis site.
