On July 18, 2013, a massive update was released in the Japanese version of Dynasty Warriors Online, changing the name of 真・三國無双 Online to 真・三國無双 Online Z.

This update adds the new feature of "Weapon Swapping" similar to Dynasty Warriors 7. Characters and soldiers have been remodeled with their Dynasty Warriors 7 appearances. The intro of the game has been changed, featuring the same three characters from the first in a revised state.
