Mod Installation

Mods for SimCity 2013 are comprised of a number of file types and structures, most noteably a .package file  containing all of the relevant data for that mod.

Unpacking
Typically, a mod will be distributed in a compressed format which must be uncompressed before use. These formats may include:
 * .zip
 * .rar
 * .7z

Folder Location
For SimCity to load mods, the files must be placed in a specific location on the users hard drive.

Windows 7 (64 Bit)
C:\Program Files (x86)\Origin Games\SimCity\SimCityData

or

C:\Program Files\Origin Games\SimCity\SimCityData

Mac OSX
Applications/SimCity/Contents/Resources/SimCityData

Installation
SimCity 2013 mods do not require special installation. Placing the .package mod folder in the above directory will automatically load the mod and replace existing assets or add new assets to the game.
