Woah, the action looks amazing. The Predalien looks spectacular beating the hell out of old Wolfie, she has my vote for the final battle.
Go Chet!
Gotta love the bit where she forces Wolfie backwards into the wall or when she sends him flying form the tail whip.
Not to mention every shot of Wolf was spectacular, I had a Predogasm when I saw that Tracker from Predator return.
