Welcome to PROJECT MOD (tentative title), a sandbox platform where anyone can freely create content! Built with MapleStory IP, Project MOD provides simple to professional-level creation tools for the users to construct their own virtual world using not only the assets provided by MapleStory IP and other games of Nexon, but also the assets uploaded by the users themselves. PROJECT MOD enables content development across both PC and Mobile platforms and has two different modes, EASY Mode and PRO Mode, to accommodate users with different needs in creating content. The EASY Mode provides templates to make development on Mobile convenient. These templates include but are not limited to RPG, Platformers, and PvP. The PRO Mode features an integrated development environment that supports IntelliSense and has an error tracking system consisted of a debugger, call stack, and logging system.
