Since going live on PlayStation Store, Horizon Zero Dawn recently gained a new story mode alongside the PS4 Patch 1.32 features outlined below complete with a trailer video! 
To quote from Guerrilla Community Manager Jeroen Roding on the update:
While development on the Horizon Zero Dawn expansion The Frozen Wilds is in full swing, we’re still finding time to add improvements to the main game. Last month’s Patch 1.30 added a new difficulty setting called ‘Ultra Hard’ which, as the name suggests, provides a greater challenge for hardcore Horizon Zero Dawn players.
Today’s patch adds a difficulty level that does quite the opposite: ‘Story’ difficulty allows you to immerse yourself in the narrative of Horizon Zero Dawn and the exploration of Aloy’s world without having to worry too much about combat.
Among the most noticeable changes, ‘Story’ difficulty boosts the player-inflicted damage and reduces the player-received damage considerably, making the combat encounters manageable for less experienced players.
It is our hope that the new difficulty setting will help us welcome more players into Aloy’s quest to discover her identity and the mysteries of the world she inhabits. In addition to the ‘Story’ difficulty, Patch 1.32 includes several fixes as outlined in the patch notes.
If you have a chance to try out ‘Story’ difficulty, we’d love to hear your thoughts! We’ll have more information on The Frozen Wilds soon, but in the meantime, keep an eye on the official Guerrilla Twitter and Facebook pages for all the latest Horizon Zero Dawn related news and developments.
And from the Horizon Zero Dawn 1.32 Patch Notes:
LATEST PATCH: 1.32
We’re pleased to announce that Patch 1.32 for Horizon Zero Dawn is available now. This patch fixes a number of technical issues, progression issues and crashes as outlined below. This patch also adds a new difficulty setting: Story.
NOTE: This list may contain several spoilers!
