Ubisoft stopped as many people as possible from getting this skin. I fulfilled all the requirements to get it, and they refused to give it me.
It was leaked a few months ago that Kapkan and Finka would be getting DbD cosmetics. That being said, I think Kapkan will be Trapper or Blight, Finka will be Skull Merchant.
Caveira will absolutely get cosmetics in DBD. As for Siege, I guess original killers that Behaviour made (Trapper, Huntress, Spirit etc)
is there a reason why this map stayed in Situations but all others got replaced by their rework?
