I don't know if this has been posted yet, but the updated physical edition of Hunting Grounds is up for preorder on various sites. There's no mention of Feral but Jungle Hunter is among the 10, film specific, Predators listed as being included.
Wasn't Jungle Hunter a preorder bonus only for the original release? And the fact that only film specific Predators are listed, with no mention of Feral, as being included is interesting.
