tModLoader

tModLoader, released in 2020, is an open-source modification framework built upon the sandbox adventure game Terraria, allowing players to create and run community-made content. Its core gameplay loop involves managing and integrating user-generated expansions that introduce new items, mechanics, and progression paths across RPG, Platform, and Strategy genres. Distinctive features include a dedicated mod management interface and the infrastructure necessary for deep game alteration, providing continuous, player-driven content variety for those on Linux, Windows, and Mac.
