When the Season Pass is redeemed, a download notification for the Dynamic spring theme appears. this is normal and the theme is bundled with the Season pass. The upcomming DLCs will appear once they are available automatically.
We also have identified that there have been misprints of the Season Pass codes in a small number of Metro Exodus' Aurora Edition in some countries. The misprint affects PS4 copies in Europe only!
We are pleased to report that the webpage to exchange incorrectly printed Expansion Pass codes in a small number of PS4 Metro Exodus Aurora Editions is live. Please go to https://keyexchange.metrothegame.com/ to exchange your code.
