Dig, Fight, and Build your way through the world of player-created mods on Terraria with tModLoader - this DLC makes modding Terraria a reality!

tModLoader (TML) is an open-source, community-driven modification and expansion of the Terraria game that makes it possible to make and play mods. TML expands your Terraria adventures with new content to explore created by the Terraria community! TML allows players to create and play Terraria mods and is designed in such a way so that you can play alone or together with friends - with one mod or with multiple, choose to play however you like!

NOTE: It is required that all your friends also install TML if you want to play together; it is not possible for vanilla users to play with TML users.
