Check the cameras to see where the alien is. If he's at the door, lock it. If he's not, unlock/don't lock the door. When you hear a loud bang, search for the time bomb using the cameras. Once you find it, click it. Keep the power going by saving power when you don't need to use it. (Locking doors uses power and so does using cameras). The phantoms don't do anything. They just block ur vision.
