Game Modding Through Reverse Engineering by Sander Strand

This course is a hands-on deep dive into reverse engineering through game modding. You’ll move beyond copying scripts and start analyzing real games at the assembly level, building external mods and a custom modding framework from scratch.

🎯 What you’ll learn

• Analyze a game’s behavior in memory using Cheat Engine and debuggers
• Read and interpret x86/x64 assembly instructions to understand program flow
• Build external game modifications in C++ that change in-game behavior
• Implement a functional ESP overlay by reverse engineering a real game
• Design and create a basic mod loader framework from scratch

✅ Requirements

• Skills: Solid experience with C and C++ programming, especially pointers and object-oriented programming. Familiarity with CMake and vcpkg is helpful.
• Tools: Windows PC.

📝 Description

This course is a reverse engineering journey disguised as game modding. You’ll learn to look under the hood of real games, understand their mechanics at the assembly level, and use that knowledge to build external mods. The focus is on the thinking process behind analysis, not just step-by-step instructions.

You’ll work with Cheat Engine and Ghidra to map memory structures, trace execution with debuggers, and then write C++ code to modify behavior. The highlight is building your own ESP overlay from scratch — and understanding everything that goes into it, from entity lists to projection matrices.

By the end, you won’t just copy mods. You’ll have the skills to reverse-engineer any game and create your own modding tools, independent of existing infrastructure.

🧑‍🎓 Who this course is for

• Programmers curious about reverse engineering and low-level game behavior
• Game developers wanting insight into how their games can be inspected and extended
• Programmers comfortable with C or C++ who want to understand game internals
• Game modders with prior programming experience but no reverse engineering background
