There’s no need to subscribe to Xbox Game Pass as Fortnite will remain free-to-play through Xbox Cloud Gaming.
Epic Games and Microsoft are partnering to bring Fortnite to Xbox Cloud Gaming.
Xbox Cloud Gaming is not the main benefit of an Xbox Game Pass subscription, which gives members access to a library of games, including first-party Xbox titles.
Xbox Cloud Gaming lets users play games instantly without needing to install a game onto their device locally.
