Wait, why are you reading this? You know that the Medal of Honor multiplayer beta is live for the PS3 right now – don’t you?

Beta access is reserved for those who pre-order the full version of Medal of Honor, EA and DICE’s modern-day war shooter that hits the PS3 this October. Luckily, we’ve got 18 beta code vouchers* to hand out to loyal PlayStation.Blog readers – keep an eye on the official PlayStation Twitter feed to find out how to win later today. To get a head start on the giveaway, watch the following video (very) carefully.

**Note: If you do win a beta voucher, you must redeem it on the official Medal of Honor site and specify PS3 to get a code you can redeem on the PSN Store.

At the 2010 E3 Expo last week, Medal of Honor executive producer Greg Goodrich and creative director Richard Farrelly give us a primer on what’s new (modern-day Afghanistan with modern-day weapons), what’s unlockable (Tier 1 Operator status and…beards?!), and what’s planned for the final release of Medal of Honor this fall. At a high level, our E3 multiplayer session highlighted Medal of Honor’s class customization. You can choose between the long-range Rifleman class, which excels at distance-based fighting; the Sniper class, which focuses on long-range marksmanship; and the Special Ops class, which packs grenades and faster-firing weapons for close-range domination.

The weapon modification system also stands out for its modular, ultra-customizable nature. For instance, the Rail slot can be equipped with a red dot sight, iron sights, or a combat scope; the Barrel slot can take a suppressor or muzzle brake. Each mod offers its own advantages and disadvantages, and when you factor in Medal of Honor’s variable ammunition types (hollowpoint rounds, shotgun slugs, extra mags), you’re looking at a highly personalized multiplayer shooter.

Peep the interview video, follow us on Twitter, and prepare to take a shot for a slice of Honor. Salud!
