After its creator Epic Games implemented a workaround to duck Apple’s hefty developer fees, Fortnite has vanished from the App Store. The popular game’s disappearing act came the same day that Epic added a new direct payment option for in-game currency on mobile, offering an enticing 20% discount for players who pay the company for its virtual V-Bucks rather handing that money to intermediaries Apple or Google.

“Currently, when using Apple and Google payment options, Apple and Google collect a 30% fee, and the up to 20% price drop does not apply,” Epic wrote in a blog post introducing the new option. “If Apple or Google lower their fees on payments in the future, Epic will pass along the savings to you.”
