Always make a backup of your game folder before installing custom files. It’s recommended to use a separate install to avoid file mismatch errors when joining multiplayer servers. Be aware that some Mutators & Addons might be various older version of TO and might not work on v3.4 or v3.5
When you are have trouble extracting files use 7-Zip to extract all various filetypes you might encounter like 7z, zip, rar etc.
Custom Maps Section
All the 2100+ Custom Maps are tested and working on TO:AOT v3.4 and v3.5. They contain all required packages in each individual map download. To install them simply drop the archive in your TO folder, click “Extract here” and the map is installed with all files in the required folders. These maps will never overwrite default/original files and all maps are packed from the same package collection. Where possible the original readme files are preserved.
Other Maps Section
It’s not recommended to mix files from the Problem Maps or Old Map Files with maps from the Custom Maps section. The Problem Maps contains maps with missing packages, corrupt files and all maps that didn’t work on TO 3.4 and 3.5 when all .unr files were tested.
The Old Map Files contains some of the original map and mappack files that started the file archive. These don’t include all retrieved maps, also the maps obtained from various redirects are missing. Most downloads will have missing packages and some include packages that overwrite original v3.4 and v3.5 files. You can however find some SWAT and TO2 Maps there.
Installing Custom Files
