As determined through the course of the trial, Epic initiated "Project Liberty" by first introducing a standard patch to Fortnite that had to be approved by Apple and Google, but which had secretly contained code that would allow users to be able to purchase the in-game currency, "V-Bucks", directly from Epic. Epic did not make mention of this feature to Apple or Google, so the patch was approved.[16] Then, on August 13, 2020, Epic released a hotfix (which did not require prior approval) to the mobile versions, triggering visibility of this purchasing option. At the same time, Epic announced for all platforms that purchases of V-Bucks directly through Epic would be discounted by 20%. For iOS and Android users, Epic cautioned users that if they purchased through the Apple or Google storefront, they were not given this discount, as Epic said they could not extend the discount due to the 30% revenue cut taken by Apple and Google.[17]
