TL;DR: In part 1, we enabled remote debugging and reverse engineered our way to player data via Chrome DevTools. Now, I'll demonstrate how to create persistent cheats in Vampire Survivors via an internal overlay coded in HTML, CSS, and JavaScript. This is a great primer for anyone not familiar with web languages. The lessons learned in this series are directly applicable to aspects of reversing and modifying JS code, whether in an Electron app or via a web browser! I hope you learn something new and useful. =)
