I thought of that too. But the exo suit is only as good as the person wearing it and doesn't cover your face. If I have an exo suit and some mma dude sucker punches me it's going to be light's out. He punched her first when she was trying to save the guy, she didn't see it coming and was fighting half dazed in which you could argue is the only reason she's alive is because she had the suit on. Lol wait...Did he punch her? He lunged at her with a knife right? Yeah that scene could've been handled better.
