BioWare releases Mass Effect 3 demo for PC, Xbox 360 and PS3 that will provide both single-player and multiplayer preview of the role-playing game. The single-player part of the demo offers up two scenes from the campaign. The first, the game's opener, depicts the Reapers' invasion of Earth. The second segment of the demo is from later on in the game. Shepard and his team have traveled to an alien world in order to win their support in the war against the Reapers. BioWare estimates that this single-player preview will take about 1-2 hours to finish.
The demo's multiplayer portion is only accessible today if you own Battlefield 3 and its Online Pass. Otherwise, you'll need to wait until the 17th to play it.
