In this chapter, we introduced cocos2d and its most relevant modules. We developed our first application to get started with the library, and later we built a simplified version of Space Invaders.

This version can be extended by adding defense bunkers or more random values to the possible scores of the mystery ship. Besides, if you want to change the visual appearance of the invaders, you can edit the sprites and create your own enemies!

In the next chapter, we will develop a complete tower defense game, with transitions between scenes, enhanced display information, and complex menus.
