Epic Games has accused Samsung of making it too difficult to download its massively popular video game Fortnite on certain mobile devices.

Some users may know that Epic Games, the developer of Fortnite, has had its own app store for a while now, the Epic Games Store. The company also won an antitrust lawsuit against Google last December that found Google held an illegal monopoly on app distribution and in-app billing services for Android devices.

The “Fortnite” maker claims the tech giants colluded to place onerous restrictions on app stores created after Google lost an antitrust case.
