Metal Gear Online beta is live now? Oh no, it couldn't be. You see, it's only the 16th and, as we all know, it won't be available for download until the 17th. But evidently the PSN gatekeepers have let this 741MB download loose a day early so, if you've got a preorder voucher for the beta (see above), you may want to get downloading. Or not ... you still won't be able to snap your buddies' necks until the beta kicks off on April 21.
