With this chapter, we wrapped up the discussion on multiplayer game development although it covers a topic that must be a deep part of your game development from the beginning. Remember that security cannot simply be added at the end of the project; instead, it must be built in deliberately with the rest of the software.

We saw some of the most basic security vulnerabilities in browser-based games as well as common ways to protect your games against them. We also talked about a few techniques that no serious game should be built without. Finally, we looked at how to implement some of these techniques using existing open source tools through Node's Npm.

In conclusion, now that you have cleared the last level of this journey of learning the basics of multiplayer game development in JavaScript, I want you to know that as exciting as this might have been, your journey is not quite over yet. Thank you for reading, but the princess is in another castle! You must now get busy with writing the next multiplayer game that will take all players through a journey full of fun, entertainment, and real-time awesomeness. Game over!
