the shuriken is steady to aliens acid, but the smart disk it's not in the movie first alien is the "Predaalien" it seem the movie wont be so cool. There is a scene, one Predator fight with alien,but I'm not sure ALIEN OR THE PREDAALIEN,but I'm sure one thing the movie wont bi so cool, the first movie AvP TWO predators they die from one alien this is just not right the first predator die so quickly, and the AvP2 will be the same.
