Just got my Ultimate Dog Aliens in today!
The only difference that I can identify are: the ball joint inside the neck (so nothing you can see, the outside seems the same) has been redesigned and allows his head to go further back, which is nice when he's on all fours. His double jointed knees were redesigned. That is it.
He comes with 2 sweet Queen Chestbursters.
Here he is in the package.
I did get 2 of them because...you can never have too many Aliens!
Here is his first accessory, Queen Chestburster curled up, like the logo for the film.
Here is his other accessory, Queen Chestburster for your Aliens collection.
Here he is next to all of my Dog Aliens (please Neca...no more!)
2 Ultimate, 2 Grey, 2 Brown, 2 Red Genocide, 2 Video Game, 1 McFarlane
Here is my entire Neca Alien 3 collection.
Here is my YouTube review on it.https://www.youtube.com/watch?v=TuvzvTi03LA
