A new version of the Line of Sight: Vietnam multiplayer demo has been released, this sample of n-Fusion's Vietnam War no longer requires a FilePlanet registration key to install (or as it's described by Worthplaying, this is the "free, non-exclusive, non-key requiring, non-ezpad version"). The 170 MB file can be downloaded from 3D Gamers, FileShack (registration required), Gamer's Hell, and Worthplaying.
