Those planning to purchase Call Of Duty WWII, the new entry in the series developed by Sledgehammer Games also launching on PC and Xbox One, should be prepared to download a huge amount of data.

According to Charlie Intel, the digital PlayStation 4 edition of the game is going to require a minimum 80 GB of free HDD space. The actual download will be slightly lower, as the game is downloaded in a compressed format, but it may still take some time. With the Xbox One version of the game requiring half the amount, it’s likely that the PS4 download comes complete with higher resolution textures for PlayStation 4 Pro.
