Video: ‘Mass Effect 3’ Multiplayer Trailer. Let’s Save The Uni Together, Guise.

Mass Effect 3 got itself some multiplayer co-op thing and such, and here’s a trailer and info.

Joystiq:

There’s one important aspect of the  Mass Effect 3  multiplayer experience, called “Galaxy at War,” that we hadn’t heard yet. Well, there are several that we  still  haven’t heard — like what Galaxy at War is outside of the co-op mode — but we’ve just learned of one.

It’s the Online Pass content.

The Galaxy at War feature is unlocked via a code included in new copies, EA revealed today. If you don’t have the code (because you don’t have a new copy) and you want to engage in multiplayer, you’ll have to pay extra.

What do you think? You in?
