If you have not received the email with your code for the summer outfit please be aware that the delivery of the emails was throttled due to the amount we had to send out. So have another look in your inbox and junk/spam folders and it should be there now. If you're on gmail it may have also gone to your promotions folder too.
The email is called 'NEW OUTFIT UNLOCKED' from email@example.com. You may also want to whitelist that mailing address too!
Redeem the code by heading to the Games section on the top left of the Steam client and select 'Activate a Product on Steam'
Enter your code there.
If you've redeemed the code and the outfit isn't showing up or you're receiving error message which reads "Steam failed to install (app configuration unavailable.)
Right click on Worlds Adrift in your Library, select Properties > Local Files > Verify Integrity of Game Files.
Please bear in mind that the Summer Outfit is not technically purchasable DLC content so it will not appear in the DLC tab.
Once you've done that the outfit can be found in the 'Stash' tab under 'miscellaneous.'
If you still cannot locate the outfit get in touch by making a support request by clicking the 'chat to us' option in the bottom right, or by using this link.
