Call of Duty 4: Modern Warfare Trainer – How to Download & Use Safely (2025 Updated)

If you’re looking for a working Call of Duty 4: Modern Warfare trainer with features like unlimited health, ammo, no recoil, god mode, or super speed for the single-player campaign, here’s the complete step-by-step guide written in a clear, safe, and user-friendly way.

How to Install and Use the CoD 4 Modern Warfare Trainer

1. Download the Trainer Only download from reputable sites to avoid viruses or fake files. After downloading, you’ll get a .zip or .rar file.
2. Extract the Files Right-click the downloaded archive and extract it using WinRAR, 7-Zip, or Windows’ built-in extractor. Inside the folder you’ll typically find:
   • Trainer.exe (the main program)
   • README.txt (important instructions and hotkey list)
   • Sometimes additional files like .dll or .ini (don’t delete them)
3. Antivirus Warning (Very Common!) Almost all trainers get flagged by Windows Defender, Avast, Kaspersky, etc., because they modify the game’s memory in real time. This is almost always a false positive. → Add the entire trainer folder to your antivirus exceptions or temporarily disable real-time protection while using it (re-enable afterward).
4. Correct Launch Order (Super Important!)
   • First launch Call of Duty 4: Modern Warfare (Steam, cracked/offline version – doesn’t matter)
   • Wait until you’re at the main menu or already in a mission
   • Then right-click Trainer.exe → “Run as Administrator”
   • The trainer should beep or show “Game Found” / “Activated” when it successfully connects
5. Activate Cheats Once connected, press the hotkeys listed in the trainer window or README.txt (usually F1, F2, Num 1, Num 2, etc.). Common options you’ll see:
   • Unlimited Health / God Mode
   • Infinite Ammo & Grenades
   • No Recoil / Perfect Accuracy
   • Super Speed, One-Hit Kills, etc.

Important Safety & Compatibility Tips

• Only use in single-player/offline mode! Using any trainer in multiplayer or IWNET (even the old one) can result in permanent bans if detected.
• Match the game version If the game updated (for example, v1.7 or v1.8), the trainer might stop working. Always download a trainer that matches your exact game version.
• Backup your saves Although extremely rare, memory editing can sometimes corrupt save files. Keep a backup of your profile folder.
• Game crashes or “Game Not Found”? → Run both game and trainer as Administrator → Try setting Trainer.exe compatibility mode to Windows 7 or 8 → Make sure Num Lock is ON (some hotkeys require it) → Close overlays like Discord, GeForce Experience, MSI Afterburner

Legal Note

This trainer only makes temporary memory changes and does NOT modify or crack game files. It is intended exclusively for offline single-player use. Using cheats may violate Activision/Infinity Ward’s Terms of Service – use entirely at your own risk.
