Fortnite developer Epic Games has reportedly filed for a preliminary injunction in order to get its game back on the Apple App Store. Epic Games has alleged that the removal of Fortnite from the App Store is in retaliation to the lawsuit it's filed against the America tech giant for denying the game maker access to developer tools. The battle between the two firms began last month when Epic Games gave users access to pay them directly for in-app purchases, in violation of Apple's App Store policies.
