From today, August 5 at 11am PT/2pm ET/8pm CEST until Monday, August 8 at 11am PT/2pm ET/8pm CEST, Naughty Dog is hosting a Relic Bonus Weekend in Uncharted 4: A Thief’s End Multiplayer.
During the bonus weekend, you’ll receive an additional 50% Relic bonus for every Multiplayer Challenge completed:

Alongside winning matches or completing Trials, Challenges are a great way to earn Relics in Uncharted 4 multiplayer. Whether it?s racking up downs with a certain weapon, mastering a specific Mystical, or hitting another multiplayer milestone, Challenges offer big Relic rewards, which can then be used to unlock new vanity items, boosters, hero weapons, and more via Chests from the in-game store. Regardless of which Chest you choose, you?ll always get something new – Chests never drop duplicates.
