Electronic Arts launched the Command & Conquer 4 multiplayer beta today for those who want to kick the RTS game's tires -- or tank treads, as the case may be. To gain access, users will need to sign up on the Gamespot beta page. If the site runs out of keys, EA states: "DO NOT WORRY." There will be a "short waitlist" created, if necessary. For those who don't want to bug-test the game (remember when people got paid for that?), Command & Conquer 4 declares full-scale war on its March 16 release.
