While he offers no citation, the same Reddit tipster who absolutely nailed every detail of the Mass Effect: Rebellion Pack nearly three weeks before Sony's Hong Kong website outed it, is back at it again with information on Mass Effect 3: Earth the upcoming multiplayer extension.
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!
I've reached out to an Electronic Arts representative for Mass Effect to get a confirm, deny or no comment. Any uttered will be updated here.
