We're sorry to say you can't. Promo codes were a part of our early bird special and are not available now that the game has launched. Players cannot buy Atlas Bucks online. However, there are plenty of places to collect free Atlas Bucks! Check out the free shop ads, the merchant platform, the diamond hunt, and referral rewards.
For players who preordered Atlas Bucks prior to the game's launch and need help finding a missing code, please contact an agent via our support chat. Be ready to provide your name, email, date of purchase, and the last four digits of the card you used for your preorder.
