How do I pick either Corruption/Crimson?

Unfortunately, we can not provide the selection to choose between Corruption/Crimson on our servers but you can still easily pick either Corruption/Crimson by creating one locally and [uploading your own world](https://help.aleforge.net/article/319-how-can-i-use-my-own-world-with- my-terraria-server).

Please make sure to set the difficulty, world size, and any other world- related setting before generating the world as these values can not be changed after generation and you will have to make a new world if you want to change the difficulty. The Difficulty setting in the panel is only used when making a new world.
