After just watching the South American DLC trailer, i remembered that "oh, that's right, there was a melanistic tiger in one of the "The making of planet zoo" videos.I went back and at 4.15 in "The making of planet zoo | Ways to play", there is a very nice shot of the melansitic tiger, almost facing the exact same way as a regular tiger. Now, when do we get to have more "genes" than leucism? It is greatly missed!
