The developers ofPhasmophobiaare reinventing the way you play the game - or at least, that’s what theirlatest blog postwould have you believe. The patch notes for update v0.13 are out, and the content within has already made it to all platforms.
The game already puts you asboth a hunter and the hunted- and while that remains true, the exact way you achieve your goals has been overhauled dramatically.

In short, here’s what’s new - media-collection has been completely reworked, with new photo types, and two new kinds of media: videos and sounds. You’ll now also need to collect ‘unique’ forms of media to get the best results - no duplicates!
The game’s progression systems have gotten a few changes, and new optional objectives offer fresh ways of earning that progress. And then come the CCTV changes - you can now get a lot more information from the (relative) comfort of your truck.

These, plus a huge wave of general bug fixes, make up the bulk of Phasmophobia’s v0.13 update. And if you’re looking for a more detailed breakdown, Kinetic Games has you covered.
