Horizon Zero Dawn Remastered offers a range of technical improvements on PS5 and PS5 Pro that actually sound pretty worthwhile

One of the most controversial announcements from last night's Sony State of Play presentation was undeniably the reveal of Horizon Zero Dawn Remastered. This enhanced version of the 2017 open-world PlayStation game is set to arrive on October 30 and is coming to PlayStation 5 and PC.

While it's easy to dismiss this release as a pointless upgrade, some of the technical information that was recently shared on the PlayStation Blog is actually quite promising.

A range of improvements have also been made to the world and overall performance, which the post said aims to «bring the game to the same visual fidelity» as Horizon Forbidden West.

Of course, these are just promotional shots so I'll be reserving full judgment until I have my hands on a copy of the game,  

Even if these visual changes aren't for you, Horizon Zero Dawn
