The Redacted client requires you to own a legitimate copy of Black Ops 2. It does not crack the game; it redirects network traffic. However, because it bypasses Steam achievements and VAC, it exists in a gray area. For offline/LAN use within a private home or venue, you will never face legal action.

Technical challenges

Install the game via Steam or disc. Run it once online to ensure DirectX and VC++ runtimes are set up. You do need to log into multiplayer or Zombies.

: Secure the Redacted LAN/Offline files (typically a "Redacted" or "RAW" folder) and move them into your main game directory.
