Mass Effect 3 launches in North America in less than 24 hours! We hope you ready to start the war to take Earth back and have secured your copy of the game via digital pre-order on PSN (don’t forget that you’ll receive a bonus weapon and exclusive PS3 theme).

The development team spent a great deal of effort to make sure that those who are just joining us in the Mass Effect Universe are able to jump right into the game without missing a beat. To maximize your enjoyment of the game right away, you can download Mass Effect 3 beginning at 12:01am Pacific Time TONIGHT. Start your download, get some rest, and wake up refreshed — and prepared to launch all-out galactic war against the biggest threat to ever hit Earth.

If you are unfamiliar with the game, the Earth is under attack by an ancient alien race known only as the “Reapers.” They have launched an invasion, leaving nothing but a trail of destruction in their wake. Earth has been taken, the galaxy is on the verge of total annihilation, and you are the only person who can stop them. The price of failure is extinction.

Additionally, the @alliancenewsnet is covering the Reaper attack in Los Angeles live on Twitter. We will be taking refuge at our launch parties beginning at 8:00PM Pacific Time and streaming the events with special guests.

The war to take Earth back has begun! Only you can decide how it ends…

It’s been one week since our Mass Effect 3 demo became available and everyone at BioWare is incredibly pleased with the response. If you haven’t already checked out our single-player and multiplayer demos (the latter is completely spoiler free and a bit addicting!), I suggest you try them to see what all the fuss is about. Our development team worked hard to ensure that Mass Effect 3 is available at the same time for PS3 as it is for other platforms, a development milestone we’re happy to celebrate with the PlayStation community!

Today, I want to let you know about an exclusive offer for anyone who pre-orders Mass Effect 3 via the PlayStation Network. When the PlayStation Store updates later this afternoon, you’ll be able to pre-order to download a digital copy of the game (available 3/6 in the US) and receive the M55 Argus rifle to complement your in-game experience.

The Argus is a high-powered rifle and an excellent close-range weapon. Its bursts of fire ensure ammunition conservation during lengthy conflicts. Law-enforcement agencies across the Mass Effect galaxy are adopting the Argus as their standard rifle, as much for its intimidation factor as its suppression power.

Along with that in-game bonus weapon, Sony Computer Entertainment America and BioWare would like to offer you a special Mass Effect 3 PS3 theme—only available for digital pre-orders. Once the game has launched, these offers will no longer be available, so if you haven’t done so already, secure your copy of Mass Effect 3 later today when the PlayStation Store updates and prepare for the Reaper invasion!

Let us know what you think of our pre-order offer and the Mass Effect 3 demo on Twitter!

Hello everyone! Mass Effect 3’s new demo is launching later today on the PlayStation Network. Voted “Most Anticipated Game of 2012” at the Spike Video Game Awards, Mass Effect 3 plunges you into the boots of Commander Shepard, a decorated marine and war hero, as players lead the charge in an all-out galactic war against a nearly unstoppable foe.

Today marks the arrival of our single-player demo for the PS3, giving you a taste of what to expect when Commander Shepard takes Earth back on March 6th. When you download and play the demo, you’ll see that how you fight the war is entirely up to you. Choose your appearance and pick from a variety of specialized combat classes, each with unique and devastating abilities. As you progress in this war, you’ll choose which abilities to specialize in, which weapons to bring into battle, and which characters will join you in combat.

There’s more to this demo, though – starting on February 17th, PS3 owners will be able to play multiplayer for the first time in the Mass Effect universe! As a special bonus, Battlefield 3 owners who have redeemed an online pass on the PlayStation Network will get early access to the multiplayer demo starting today, February 14.

I’d say more, but I’ve got Valentine’s Day plans with Commander Shepard! Check out the demo when the PlayStation Store updates this afternoon.
