The support launched alongside Terraria's latest patch today: version 1.4.2. However, after over 10 years of development, the Minecraft-like sidescroller is finally receiving Workshop support. It makes modding your favorite games fast and efficient, though some popular titles, such as Terraria, have resisted its implementation so far. Highly anticipated: Steam is loved for many reasons, but its built-in support for user mods through the Workshop system is pretty high up on that list.
