By now, we are surely all familiar with how this whole Mass Effect 3
multiplayer weekend thing is supposed to work: "Hey N7 Marines, something about the state of the galaxy, something about the Reapers/Geth/Cerberus, perfunctory lore justification, etc, go kill stuff and we'll give you stuff."
It's a good system, so why mess with it? This weekend's Operation: Ballistic challenge charges individual soldiers with earning a gold weapon medal for assault rifles, heavy pistols, shotguns, sniper rifles, or submachine guns. As per usual, the reward for successfully completing the task set before you is one brand-spankin'-new Commendation Pack.
