As an important update, this also carries a huge file size. The download size for World War Z update version 1.03 is approximately 15.5 GB on the PS4, which is massive on its own. It is not available yet for PC or Xbox One, but the developers did release an earlier patch to resolve the issues with the save data and party invites on PC.
