This two-second voice line from For Honor has Holden Cross speaking the words 'These warriors don't have to die' in a firm, weary tone. It carries a solemn, pleading feeling, as if he is trying to stop a battle before it turns bloody. The clip comes from the game's story, where Cross argues for mercy over needless fighting.
