Mass Effect 3 hosts a five-day multiplayer event this week

Mass Effect 3 hosts a fiveday multiplayer event this week
BioWare has announced another Mass Effect 3 multiplayer event, but this is no standard combat skirmish: Admiral Hackett says this is "the largest-scale attack in the brief history of this war."

Instead of just a weekend special, Operation Lodestar will last from today through March 10, which means you'll have five days to complete all three tiers, and earn three Commendation packs and a special banner.

To pick up all three rewards, players will need to finish and extract from missions against all four enemy factions on Platinum difficulty. Extracting on any difficulty wins you the first award, and beating Silver difficulty wins the second. It'll be good practice for taking on the Citadel DLC, which you can also find in Mass Effect 3 starting this week.
