A new multiplayer Mass Effect 3 expansion pack has been confirmed by Major Nelson.

The pack titled ‘Earth’ is set for release next week on July 17th for Xbox 360. PC and PS3 dates have not been announced yet.

Major Nelson decided that he’d make the announcement over BioWare and EA, so when they make a formal announcement details on other platforms should emerge.

No extra details on the title have been released, however a product listing leak says that six new player classes and three new maps will be added to the multiplayer mode.
