Requirements
Installation Steps
Prepare the PC and Windows
Before launching MEDUSA LITE for Escape From Tarkov, follow the developer's current system preparation guide: http://81.177.6.111/mrx/instruction.html On Windows 11, review the Core Isolation requirement and reboot after any change. The former win11_driver_OFF.reg file is no longer available, so use only the current steps on the developer page.
Download the MEDUSA loader
Download the loader from the developer's official link: http://81.177.6.111/mrx/loader/builds/download.php Current guide and Windows 11 requirements: http://81.177.6.111/mrx/instruction.html
Activate the key in the loader
1. Run the loader as administrator (right-click → 'Run as administrator'). 2. Copy the seller key into the license key field. 3. Click activate and wait for the success notification. 4. After activation you'll be redirected to the inject page — click inject. 5. Wait for cheat initialization to complete. 6. The window preparing mapper... will appear.
Launch EFT and activate the cheat
1. When awaiting game window appears — launch the BSG launcher and Escape From Tarkov AS ADMINISTRATOR. 2. Wait for the EFT main menu. 3. Wait 15 seconds. 4. Press ENTER — the cheat activates.
Common troubleshooting
If you encounter problems: - Loader crashes on startup — restart, reinstall, reboot Windows. - unexpected error / failure connect — check Internet, use a CIS-region VPN (Kazakhstan, Belarus, Russia). Ukraine users must use VPN — servers are blocked there. - Loader closes after inject — disable all protection, run cmd as admin: sc stop faceit sc stop vgc sc stop vgk

Run BSG launcher and EFT strictly as administrator. After loading the main menu wait 15 seconds and press ENTER.
Open the current Windows 11 section in the official MEDUSA guide: http://81.177.6.111/mrx/instruction.html Review Core Isolation, follow the developer's current steps, and reboot. Do not use the old win11_driver_OFF.reg file because that link is no longer active.
