Back in October they revealed that Mass Effect 3 will be having a multiplayer that coincides with the single player campaign, but doesn't detract from the campaign and is purely optional. There is quite a bit of information about it, seen here, but we have yet to see it in action. It should be clear that the mass effect multiplayer is almost purely action, which people keep complaining about and expecting the multiplayer to have rpg elements, but it looks to be a fun add-on onto the exciting singleplayer campaign. Check out the new gameplay trailer and if you want information on how multiplayer will work check out the FAQ from my first post about multiplayer. We should be getting a demo for Mass Effect 3 sometime in the beginning of February and the game itself comes out on March 6th for PC, Xbox 360 and PS3.
