Mass Effect 3 Multiplayer/Challenges

Challenges are a cooperative multiplayer gameplay mechanic introduced in Mass Effect 3: Retaliation. Completing certain goals will complete a challenge, providing the player with Challenge Points, which serve as measure of their skill. There are two types of challenges: Silver challenges involve meeting a certain statistical requirement in order to be considered completed; Gold challenges can only be completed if all of the Silver challenges they cover are unlocked. Completing a Gold challenge unlocks a banner and title card to display in the match lobby. Challenges can be completed multiple times.
