Looks as though Fileplanet has a sneak peek at the next Command and Conquer game available for its subscribers. The multiplayer demo looks like resource hog though, so don't expect silky smooth gameplay with these requirements:
The Sneak Peek was the Multiplayer Test created in November 2002, so it not optimized and does not reflect the final retail product. To run the Sneak Peak, you MUST meet the following requirements: - 2 Gigahertz CPU minimum - 512 MB RAM minimum - GeForce4, or more recent Direct3D-capable video card - A current FilePlanet Subscription
Still, if you're aching for a look at this game, here's you chance. Get the file here.Thanks for for the tip, Valcron!
