As Fortnite gears up for an App Store relaunch, Epic is cranking up its Rewards program to encourage people to use its payment system instead of Apple's

As Fortnite slowly grinds its way back to iOS devices in the US, Epic Games is offering players a deal: Make purchases in Fortnite—or Rocket League or Fall Guys—using Epic's payment system and you'll get back 20% of what you spend in Epic Rewards.

That's a big boost over the usual 5% offering on Epic Games Store purchases, and it's simple math, as Epic demonstrated with this handy-dandy image: When, for instance, you spend $23 on 2,800 V-Bucks, you can get $4.60 back in Epic Rewards, or you can get nothing.
