How do I obtain DLC (downloadable content) for my game?
The process for purchasing DLC is slightly different depending on where you bought the game and the size of the DLC. If your game supports DLC, full instructions for downloading and installing it can be found in the FAQs for that game.
However, in most cases you can view all available DLC by following these instructions:
Double-click on the game’s application icon while holding down the Command (⌘) key. The pre-game Options window will appear.
Select the DLC tab.
The DLC tab contains a list of all available DLC for your game and descriptions of their features. Click the button next to the DLC you want to purchase to be taken to the relevant store page for that DLC (usually the Feral Store, the Mac App Store or Steam).
NOTE: Some games will need to be updated before the DLC tab appears in the pre-game Options window. Instructions on how to update your game can be found by viewing the Updates page for your game on the support site.
