I would like to know where to download Crysis Wars, does anyone know where to get it?

Steam or EA Downloader. There's a few other places that do it too, i believe, like Direct2Drive.

I don't know how if it still is today, but it was on a big sale (75% off I believe) yesterday on Steam. And remember, you'll be buying Crysis Warhead. Crysis Wars is the multiplayer part that comes with it.
