Bioware announced today on Twitter that the multiplayer portion of the Mass Effect 3 demo, which became available on Tuesday, is now open to everyone. The cooperative multiplyer access was originally scheduled to go public on Friday (2/17), but with all the positive feedback they've been getting it's not surprising they decided to make it available to all a day early.
If you haven't had a chance to check out the cooperative multiplayer, I highly suggest you do. The gunplay has been further improved over Mass Effect 2 and the stripped down RPG elements have been bolstered with more evolution options for powers. Weapons have also received more customization options. Firearms can be outfitted with scopes to increase accuracy, more efficient heatsinks to increase the number of shots fired before it has to be ejected, etc. All the customization allows the ability to create wholly unique characters personally tailored to your play style.
