I bought Shattered Union a couple of years ago, and it stopped working when I went onto Windows 7 64. Bought it again (for 29p !) on Steam. Won't work, Steam not interested in nhelping, refering me to a looped 2k site (thank you steam I dont think) Steam are completely unhelpful, and 2k are worse. Got loads of games off Steam, and now look to avoid anything Shattered Unions' makers do.
