The BioWare Blog has word to expect a playable demo for Mass Effect 3 on February 14th, offering the chance to sample the upcoming RPG sequel. Here's the deal: "The demo will be available on PC, Xbox, PS3 beginning February 14, 2012. You will be playing through the opening level “Earth” which is under attack by those nasty Reapers. This version of the demo will also introduce the Mass Effect 3 co-op multiplayer mode and for the Xbox 360 players out there – Kinect functionality. Fans will be able to access tons of customization options and get enough of a peek at the story that you will be inclined to play it over and over to catch all the nuances." They also offer a FAQ with system requirements, word on early access to the multiplayer portion of the demo, and how to qualify:

What content will be included in the Mass Effect 3 demo?

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.
