Mass Effect 3 - Challenge System
BioWare will be adding a new “Challenge” system to Mass Effect 3’s multiplayer component. These challenges will not provide any form of in-game unlocks or items but will instead grant “Challenge Points”, titles and banners. These Challenge Points cannot be used to unlock anything but are simply a form of showing off your personal score.
Additionally, at some point in the future, BioWare will stop running the “Operation” events and will replace these with weekly Challenges. The good news here is that these challenges will now provide instant unlocks to individual players who achieve these weekly challenges, rather than having to wait for the global unlocks through the Operation events.
