lol at some of these posts. yes it will work on any OS, there should be no issues there. some custom maps will throw an error and make you go back to the main menu, you can type developer 1 in the console to see what the error is, but if your going to use mods on alot of the new custom maps, i would go with memory editing, you cant do as much but it will atleast work.
True, I could probably make a universal menu, with less options. We'll see what the future brings.
