Pre-order/season pass questionable??

I bought the season pass with the preorder and the newest DLC content for halo wars 2 “Nightmares” still wants to charge me. Not the first time this has happened. Can u fix or tell me why i can get it???

Hi OP - sorry but the ATN DLC is not available as part of the season pass, you need to purchase it separately. There’s a long running topic about this below your thread if you wish to add your thoughts there. It was announced back at E3 that ATN would not be included
