If you can look past the odd "BioWare Pulse" and "Exclusive Video" hyperbole in BioWare's own video (so why would it be exclusive?), there's some neat information on probably their worst-kept secret ever - Mass Effect 3 Multiplayer.

Casey Hudson, executive producer on the game, talks about what multiplayer means for the third installment of their massively popular sci-fi epic, including the option for fans to finally get behind classes and races they've encountered in the Mass Effect universe, but have never been able to play.

EA also sent out a press release today outlining their multiplayer plans:

With the Mass Effect 3: Galaxy at War system, players will fight for the survival of the galaxy against an ancient alien race known only as, Reapers, in both the single player campaign and through a suite of Mass Effect games and applications. Progress made in each of the components of the system, including the new multiplayer mode, will directly link back to the player’s main campaign, helping Commander Shepard rally the forces of the galaxy to eliminate the Reaper threat once and for all. The Mass Effect 3: Galaxy at War feature can be activated via the Online Pass code found in every new copy of Mass Effect 3.

We'll have more on multiplayer in the not-too-distant future, but for now, watch the developer diary embedded below, or click here for the HD option.
