Assassin’s Creed Unity Patch 4 seems to be up on the PlayStation 4. This latest patch aims to fix a wide variety of issues ranging from performance to graphical glitches. Ubisoft officially addressed the additions to be included in this new patch as follow.

This patch will address issues with stability and performance as well as online matchmaking and connectivity (among other fixes and improvements).

Ubisoft explained that the reason the patch size is so big is because they replaced parts of the Paris city map which had issues, which has resulted in a large patch size.

Originally, it was supposed to arrive earlier but was put on hold because Ubisoft wanted to ensure the best possible experience for the users. It is now finally available online, and judging from the file size, it seems to be a very substantial update.

Assassin’s Creed Unity was released in November on the PlayStation 4, Xbox One and PC. The game was plagued with bugs and glitches along with a terrible performance at launch. The later patches have managed to fix most of the issues but there are still some left, which should be hopefully fixed in the new patch.
