Fortnite added the Darth Vader AI with the latest update, but this move has caused a lot of controversy and some legal trouble.

The actors’ union that began striking against video game companies last summer has filed an unfair labor practice charge against Epic Games, the creator of Fortnite.

The union has now filed an unfair labor practice charge (link to the PDF is on the SAG-AFTRA website) that calls out “ Fortnite ‘s signatory company, Llama Productions” for “ [replacing] the work of human performers with AI technology” without “providing any notice of their intent to do this and without bargaining with us over appropriate terms.”
