There's a rather big chance that you enjoyed Horizon: Zero Dawn and if you don't have enough of Aloy's post-apocalyptic adventures this expansion is definitely for you. Guerilla Games added a lot of new content, including fresh, never before seen location, new story, quests, enemies and abilities.
The extended gameplay released by Sony will show you these additions in details:
Beyond the northern mountains, the borderlands of the Banuk tribe challenge all who dare enter to survive the extremes. But now this frozen wilderness harbors a new threat, and for Aloy, a new mystery - one she’s determined to solve.
Horizon Zero Dawn: The Frozen Wilds is a PS4 exclusive and releases on November 7.
