What this plugin does in more details
After Marvel Rivals Season 2 Update the game needs special signature files called .sig files before it will load extra content. This plugin changes that. It turns off the signature check and skips it completely. That means the game will now load custom pak, utoc, and ucas files even if there is no .sig file.
The plugin is called a UTOC Signature Bypass patch. It lets you add or change game files without the normal limit. With it, you can run new mods and change how the game works or looks much more freely.
However, there is one big thing to remember. Old mods will not work anymore. After the April 2025 update, the game now needs mods to be in the IO Store utoc and ucas format. Any mods made before that date will crash the game when it starts.
If you have any Marvel Rivals mods from before April 2025, you must delete them. Only keep mods that were updated to the new format. If you do not, your game will stop at launch and you will have to remove the old files to fix it.
IF YOU EXPERIENCE ANY ISSUES DO THIS:
- Manually delete your Marvel Rivals installation
- Verify integrity of game files on Steam
This is caused by some old files (e.g. Season 1 PAK files) that do not work with the newest update.
If the mod is broken (e.g. is not updated for the latest Marvel Rivals Season), use Repak.
