The Nexon launcher is a proprietary digital video game distribution platform and client developed by the company to manage, download, and update its catalog of PC games on Windows systems. Similar to other platform clients like Steam or Epic Games Store, it provides users with direct access to patch management, account security settings, community features, and game libraries for titles such as MapleStory and Mabinogi. Using the launcher ensures that players receive automated hotfixes, security patches, and seamless login authentication directly from the publisher's servers.
