Operation Prophecy, another action-packed Multiplayer Weekend for Mass Effect 3, is running from December 21st to December 23rd BioWare announced. Word is: "Our successes on Earth have given us the capability to land materiel in several war zones. However, in order to conceal shipments to the resistance, each delivery needs corresponding strikes on Reaper targets to create a screening distraction. The operations to deliberately gain Reaper attention are extremely high-risk and will require increased numbers to spread thin Reaper reaction forces. For this mission, N7 commanders, wherever possible, will recruit and command supplemental volunteer units: recent graduates of our N7 program and soldiers who bring experience from other branches."
The first Challenge is to extract once on each Earth map (London, Vancouver, and Rio), and the second Challenge is to score 100,000 cumulative points against Reaper enemies. Completion of both goals awards the player a Commendation Pack and a banner, "Hero of the Last Days"
