A YouTuber that goes by the username mkuis77 was one of those individuals that posted a video of himself unboxing the game and even showed the game being installed.
We noticed that it only took 20 seconds for the PS4 to load the game to be played. That is a very short amount of time when compared to other games. Another user reports that the installation size for MGS V: Ground Zeroes game was only 3.9 GB.
Unfortunately, the video has been removed by Konami due to a copyright claim.
