  1. Delete Multiplayer & Zombies Files (Keep only Single Player):
    • Navigate to steamapps\common\Call of Duty Black Ops
    • Delete the zone\mp_ and zone\zm_ folders. This removes ~5GB of multiplayer maps.
  2. Compress with CompactGUI:
    • Download CompactGUI (free, open source).
    • Run it on your Black Ops folder. Use "LZX" algorithm. This can shrink the game from 12GB to 7GB with zero performance loss.
  3. Use a Lan Cache or Local Steam Backup:
    • Create a Steam backup of your installed game to an external drive. You can then restore it on another PC without re-downloading.

Step 2: Download the Archive

The file will likely be named something like Call.of.Duty.Black.Ops.1.Highly.Compressed.rar (size ~2.5GB). Use a download manager (like IDM or Free Download Manager) to prevent corruption.

  2. Read comments/torrent forum threads for "confirmed malware" reports.
  3. Run the installed game offline for a few days while monitoring Task Manager for suspicious CPU spikes.

Step 4: Run the Installer

  • Right-click setup.exe → Run as Administrator.
  • Choose your destination folder (e.g., C:\Games\Call of Duty Black Ops). Avoid Program Files (x86) to prevent permission issues.
  • Select components: Usually you can uncheck "Multiplayer" or "Other languages" to save space.
  • Click Install. The process may take 30-90 minutes depending on your CPU. Do NOT force-close it even if it seems stuck—the progress bar may freeze, but your hard drive is writing.
