For anyone who wishes to test Windows Vista, I can let you know that Vendetta is not completely compatible. You have to use the backwards compatibility tool with it. Unfortunately this means that the Vista sound drivers won't be recognized and white noise is evident in all sound effects. Just to let you know.

What does it do when you try to run it?

Um. It works fine for me under Vista, but I get no sound anywhere because Creative's beta drivers crash. The game itself seems to be working fine, though.

When I try to run it normally, it starts loading then just self terminates. As far as thr sound goes, it's just a driver problem with me not having the drivers for the OS the game thinks I'm running on.
