Ce n'est pas un mod, l'auteur de la vidéo a utilisé la console pour faire ça : c'est marqué dans les commentaires de la vidéo :
"But you need to max your disposition with an NPC (Who isn't a guard) and they'll fight with you if you attack the guards. I also used a cheat to raise the Argonian copies of myself to make them automatically attack people who don't have a 100% disposition with them. (Guards automatically have a lower disposition) This meant they automatically attacked guards and townfolk."
Etc, etc...
