Security Risks of Running This Client

If you have downloaded or are considering running this file, be aware of the following proven risks:

Installation steps (template)

1. Scan the downloaded archive with your antivirus.
2. Create a backup:
   • Navigate to your BO2 game folder (example: C:\Program Files (x86)\Steam\steamapps\common\Call of Duty Black Ops II).
   • Copy the entire folder to a safe backup location.
3. Extract archive:
   • Right-click the archive → Extract to a new folder.
4. Read included README or install.txt first.
5. Replace executable:
   • If the mod provides a replacement executable (e.g., t6mp.exe), move the modded exe into the game folder, overwriting the original. If prompted, confirm after ensuring you backed up originals.
6. Place additional files:
   • Copy any provided DLLs, config files, or folders into the game directory as instructed by the README.

   • If Windows blocks the executable, use Properties → Unblock, or add a temporary exclusion while you verify safety.

   • Many offline clients include a launcher or an INI file. Edit settings (ports, offline mode, bot counts) per included instructions.

• Disable network or use firewall rules to prevent online connections while verifying the mod runs offline.

• Downloading a repack labeled bo2offlinespmpzmclientv37z that includes cracked game files is piracy.
• Always support developers by purchasing the game if you enjoy the modded experience.

Step 5: Campaign

• Antivirus quarantines files: check scan logs, restore from quarantine only if you trust the source and add exclusions.
• Missing DLL errors: ensure you copied all provided DLLs; try installing Microsoft Visual C++ Redistributables the mod requires.
• Config changes not applied: delete generated config files and relaunch to let the mod recreate them, then reapply settings.
• Black screen or rendering issues: update GPU drivers; try running in windowed mode via launch options.
