FAQ
Do you mod multiplayer or online games?
No. I strictly mod single-player games. I do not create cheats for competitive environments, bypass anti-cheat software, or work on games with active online economies.
Why must I message you before placing an order?
Unity games vary significantly in how they are compiled and protected. I need to perform a quick technical assessment (decompilation) to ensure the game’s code is accessible and that your specific request is actually possible before we start the clock on an order.
What information do I need to provide?
Please provide the name of the game and a clear description of the feature or tweak you want. If the game is an obscure indie title, a link to the Steam page is very helpful for my initial research.
Will the mod work after the game updates?
Not necessarily. Game updates often change the internal code structure, which can "break" the mod's injection points. My delivery guarantees the mod works for the current version of the game at the time of the order.
Do you provide the source code?
The Standard and Premium packages include the C# source code for your mod. This allows you to see exactly how the logic works and ensures you can have it updated by another developer in the future if I am unavailable.
Is BepInEx safe to use?
Yes. BepInEx is the industry standard for Unity modding. It is an open-source framework that allows for "hooking" into game code without permanently modifying the original game files, making it easy to install or remove.
