All of our Kickstarter backer rewards for The Bard's Tale IV are being distributed via CrowdOx. When you complete your CrowdOx backer survey, shortly afterwards, you will receive an email containing all currently available rewards for your pledge level. This includes downloads, game keys for Steam or GOG, etc.
Please check your email inbox for your backer rewards. A small number of users have also reported that their email has ended up in their spam folder; please check that to make sure it hasn't ended up there.
If you continue to be unable to find your rewards or game key, please check this page.
