Mass Effect 3's latest multiplayer bounty weekend, Operation Vigilance, starts tomorrow and will run until Sunday night. According to the operational intel: "unexpected attacks have taken out several squads and damaged vital Alliance equipment. We will deploy drones to repair damage and investigate the nature of these attacks."
Squads will be challenged to complete any mission up to level 10 - on any difficulty - without using a consumable item. The Allied Goal is to complete 250,000 escort missions across the full 72 hours. Players will be rewarded with item packs for accomplishing their squad objective and participating in the global challenge (if successful).
