The Mass Effect 3 demo will be available on February 14 to everyone. The multiplayer demo will be out February 17, but there’s a way to access the multiplayer beta before the February 17 date….
How do you get early access to multiplayer?
To gain access to multiplayer in the demo any time between Feb 14 and when it opens up for everyone on Feb 17, a player must own Battlefield 3 and have activated BF3’s Online Pass. Logging into the demo using the EA Origin Account linked to that Online Pass will automatically unlock the multiplayer section of the demo. Note that you do not have to enter a code anywhere if you have activated your BF3 online pass, the multiplayer section of the demo will be unlocked for you when the demo goes live.
There are two sections in the Mass Effect 3 demo, both included as part of a single download: The single player section includes 2 areas: the opening level featuring the Reaper attack on Earth, and a level further into the game where Shepard travels to an alien home world to seek their assistance in the war effort. This will be approximately 1 to 2 hours of content.The co-op multiplayer section includes 2 maps: Slum and Noveria. This section will be open to players who have qualified for the early multiplayer access as of Feb 14, and will then open up to all players on Feb 17
