Yes, I’m only thinking from what i saw in the movie. There could have been traps that he used up. There’s definitely mimicry which will make a person freeze up for a moment. Would be pretty cool to set Audio Decoys to have been used and been effective. It would be nice to have Hopper’s team figure something out on the fly about the PRED and how to flush him out and you can have a scene or two of counter-counter scenario.
Besides the tactics used by Dutch, the Cryo suits used by Keyes, and maybe the Fire used by Royce there aren’t many mind games in the movies. I guess Naru will have something to say about that.
