This guide will help you create your own custom hero to add to the game and optionally allow you to begin a new game using that hero at the start. XML code is provided that can be copy and pasted in to your files then altered to match the data you want. We will be creating a hero named, "Noob the New" as an example. You can use the default Notepad in Windows to make/alter the files but I recommend a free XML editor such as Notepad++ to make editing easier. XML files can be made by creating a new text document and renaming the .txt extension to .xml.
