Patch notes for World War Z update version 1.0.3 has been revealed by developer Saber Interactive on the Focus Home Interactive forums.

First off, the developers made note that this update will land on PS4 first, with patches for the Xbox One and PC versions of the game coming soon. Their game plan going forward is to “release the updates as soon as they are ready.”

The patch addresses a number of issues that Saber Interactive has been working on following fan feedback, outlined in a ‘Known Issues’ thread on the game’s forums. 

Patch 1.03 has fixed a number of issues on PS4 including problems with save games getting corrupted and progression being reset. Beyond that, there appears to have been a focus on smoothing out matchmaking, which should mitigate connectivity trouble between players.

Saber has also issued a number of balance fixes, reducing the damage of the Compact Shotgun and increasing the time necessary to save friendly NPCs to 60 seconds on lower difficulties, whilst reducing the effectiveness of AI bots. A couple of issues with trophy tracking have also been remedied. You can read the full patch notes below for more details.
