For Honor is bringing a new update later this year, adding Chinese warriors to its current ranks of knights, samurai and vikings. To promote the update, For Honor is currently free, for a week, for PC users.
For Honor: Marching Fire is coming out on October 16, featuring fighters from the Wu Lin faction including a wily general, a knife-wielding bodyguard, a warrior monk and a broadsword fighter. The update will include a new 4v4 PvP mode called Breach, in which attackers try to storm a castle, while defenders do their best to hold fast. You can watch how the new mode works in the video below.
