Aurum's Mods

Youtube Github Discord Docs Blog

Greetings! I'm Aurum, a Computer Science student and video game hacking enthusiast from Germany. Welcome to my website, where you can explore my exciting mods and projects! In my free time, I engage in researching the internal structures of various video games. Using the gathered information, I create my own modifications, hacks and tools. I always wanted to create unique maps and worlds to share with others, and discovering the world of video game modding made that dream a reality.

I have a Discord server dedicated to my projects. Click here if you want to join!
