Mass Effect 3's multiplayer mode is facing a spate of technical issues, which started being reported last night. To that end, BioWare's Tully Ackland said that the studio is looking into the issues and expects to resolve them fairly soon.
Despite the various minor hitches with Mass Effect 3's multiplayer, the mode itself remains fairly popular and is set to receive yet another DLC. Information of the DLC, which is rumored to be titled Rebellion, was leaked on the game's official forums.
According to the leak, the DLC is set to add two new fronts in which players will do battle against Reaper forces: the jungle reservoir of Firebase Jade, and Firebase Goddess on the planet of Thessia. In addition to the new fronts, the in-game reinforcement packs now include three new weapons as well as equipment, consummables, and six new classes: the Turian Engineer and Infiltrator; Vorcha Soldier and Sentinel; and the Phoenix Adapt and Vanguard.
Keep in mind that the whole thing is a purported 'leak' so take it with a grain of salt.
