Batman Arkham Knight release date is all set for June 23, 2015. But on Reddit a user has updated about a new Batman Arkham Knight Day-One Patch 1.01 version. The patch size is around 3.5GB. This would be a next pending release when the game comes out for all. Officially Rocksteady Studios has not mentioned about the same. There are maximum chances that a lot of information related to patch is mostly a rumor. As per leaked patch notes it will bring a lot of performance improvement in the game. It will also make the game more stable and offer enhanced performance. It looks like the game might have some bugs here and there and instantly after a few days this patch will be out for fixing all those stuff. Along with fixes, the patch will also add some new features like Rival Points and Batsuit Skin in the game. The patch will also add support for upcoming additional content. After when we check the Reddit post we found that it was deleted. But this information is shared by many gamers and gaming blogs.
There are also certain screenshot shared by gaming sites which says about that this patch might be real, but also there are chances that it accidentally rolled on different platforms. 3.5GB is quite a huge size which shows this patch will surely bring more additional things that are not revealed. The game is also going to get new content released in an interval of one month for the next 6 months. And this will be provided for those who are having season pass.
