Your Season Pass is actually installed! Here's the deal...

The Season Pass for Dying Light consists of the following items:

 1. Cuisine & Cargo


 2. The Ultimate Survivor Bundle


 3. The Bozak Horde


In addition, Season Pass owners have access to the latest storyline expansion, The Following.

Having said that, Season Pass is just a name - not a DLC itself, while its owners have the above items installed on their systems regardless of whether the Season Pass checkbox is ticked or not. To conclude - no worries and enjoy the DLC's!
