Warning: Never download executable files (.exe) claiming to be "Zone Updaters." Zone folders contain only .ff, .csv, and .svg files.

As of 2025, the safest sources are:

1. Plutonium Project Forums: The official Plutonium MW3 section maintains a pinned thread called "Zone File Synchronization."
2. Internet Archive (Redump): Look for "MW3 PC Zone DLC Collection" – specifically the 2024-2025 re-upload that includes the Terminal and Erosion maps.
