It was rumored last month that Mass Effect 3 would be getting more co-op DLC, specificall set on Earth. Those rumors of held to be true as Major Nelson reports a new expansion pack for the game is going live next week on July 17th for the low, low price of FREE. The pack is called "The Earth Multiplayer Expansion" and if the rumors hold up will include 3 new maps, 3 new weapons and 6 new human classes.
There seems to be more to this pack though than what was previously rumored, as a new game difficulty has been added called Platinum.

Fury: "Fury operatives use implants to fuel biotics and their incredible movement speed. These operatives wind an unpredictable path on the battlefield, moving in and out of combat before returning to unleash a sweeping biotic attack on their unsuspecting targets."
Destroyer: "The Destroyer's T5-V Battlesuit gives these strong-but-slow soldiers mech-like protection. Driven by eezo-assisted actuators, these frontline troopers carry heavy weapons onto the battlefield."
Demolisher: "The Demolisher uses grenades to attack at range and to terrorize the battlefield. Demolishers can also create a supply pylon that stocks allies with an unending reserve of grenades and thermal reloads."
Paladin: "The Paladin carries a powerful omni-shield onto the battlefield to block enemy fire. The Paladin also uses the shield as a heavy-melee weapon that, when modified with incindiery or cryo upgrades, creates a devastating combination attack."
Shadow: "Shadow infiltrators use implants to dramatically improve agility, making them slippery combatants on the battlefield. Their onomolecular blades are a menace from cover and close range."
Slayer: "Slayers use implants to dramatically improve mobility. Their dizzying sword attacks can hit multiple opponents, and the Slayer's ability to slip fire makes them hard to pin down on the battielfield."
Pics of the new classes and weapons have emerged too.
Mass Effect 3 is available for the Xbox 360, PlayStation 3 and PC with 4 player online co-op.
