It looks like Mass Effect 3 will be getting a significant multiplayer update very soon. Microsoft community fellow Larry Hryb has listed an Earth Multiplayer Expansion alongside a Tuesday July 17 Xbox release date in a blog post spotted by Eurogamer . Something Awful's gibbed has spliced some supporting details from Mass Effect 3's game files, revealing descriptions and pictures of six new elite N7 characters, new maps, three new weapons and a new Platinum difficulty mode.

EG highlight this product description of the pack: "Mass Effect 3: Earth: The fighting is fiercest when it's your home at stake! Mass Effect 3: Earth adds mods, gear, and new maps for Rio, Vancouver, and London. It features three new weapons: Piranha assault shotgun, Acolyte pistol and Typhoon light machine gun. Six new human N7 classes are also available: Destroyer, Paladin, Demolisher, Slayer, Shadow and Fury!"

Gold mode is already a pretty decent challenge, so the addition of an even more challenging difficulty tier suggests that these new items and classes could be more powerful than the baseline characters. You can increase the power of ordinary weapons by unlocking duplicate versions of them in weapon boxes, a few upgrades might be needed before we can take on that highest difficulty level. The elite N7 characters look awesome, though. Here they are.

N7 Destroyer - Soldier
