BO3 Mod Check Bypass

Bypass BO3 Mod Integrity Check (Rank Up Plugin)

📦 Overview

BO3 Mod Check Bypass is a plugin for Call of Duty: Black Ops III that patches the game in-memory to bypass the mod integrity check, allowing you to gain XP and rank up while playing with mods loaded.

🧩 Installation

1. Install T7Patch

T7Patch is required for this plugin to work correctly.

• Download the latest release from T7Patch - GitHub
• Open Steam, right-click BO3 and go to Manage > Browse Local Files
• Extract t7patch.dll, t7patchloader.dll and t7patch.conf into your BO3 folder
• Rename t7patchloader.dll to t7patchloader.asi
• Open t7patch.conf and set a username and network password

2. Install BO3 Mod Check Bypass

• Extract all files from BO3-Modded-Rankup-Plugin.zip into your BO3 folder

3. Launch

• Launch BO3 as normal via Steam
• XP and rank progression will now work in modded lobbies

🖥 How It Works

• Injects into the game via a .asi plugin loader.
• Hooks the mod check function and all known call sites at runtime.
• Redirects the mod check to always return false (no mods loaded) for rank/XP purposes.
• Modded maps and content continue to work normally.

⚙️ Features

• Compatible with the Feb 2026 game update.
• Works alongside T7Patch.
