We are now on the home stretch with our third and final game for our book—RETROformer. In this chapter, you will learn all about more advanced map building. In particular, you will be introduced to a third-party tool for creating tiles named Tiled. In addition, you will learn how to incorporate these tiles into Unity to build 2D worlds. With this said, let's jump into it.

Throughout this chapter, we will cover the following topics:

• Creating tiles
• Introduction to the program – Tiled
• Importing TileSets into Unity with Tiled2Unity

We will also cover the basics of platformer-type games to provide you with some background information, ideas, and inspiration for creating the game in this section and in your own game projects.
