Recently, Epic CEO Tim Sweeney said that they currently have no plans to update Fortnite on the Steam Deck of V Club's handheld because it is difficult to implement anti-cheating on the handheld.
Steam Deck is a relatively open handheld platform that not only runs Steam's own game store system, but also installs third-party software and operating systems, and even its competitor Epic's game store can run normally. Although Fortnite is not a steam platform game, it can run on steam deck according to normal system requirements.
Tim Sweeney said epic has spent a lot of effort to make its "simple anti-cheat" system compatible with Steam Deck, which is indeed very reliable compared to other games on Steam Deck, but the application is somewhat stretched in Fortnite.
