If you are new to Terraria and haven’t yet “completed the game” without any cheats or hacks I would suggest staying away from this until you have beaten all the bosses, etc. otherwise this will just ruin the game for you. You have been warned.

If "Use Textures" is grayed out, it's because the program can't find your Terraria directory.
It’s awesome since it negates the need to go around looking for servers and you can server-hop to as many as you’d like with no problem while looking for that perfect server.
