The barricade holds, for now. In Zombies Attacking Door, hands hammer at the wood, and one roar belongs to something much bigger. Submarine in Distress keeps a crew counting the minutes on a groaning hull. Shadow Over Us is for a threat that has not shown itself yet, when the players know and the characters do not. Watcher's Vigil scores a room crossed without being seen, and Horrors Above a chase with something overhead. Some pieces also loop, for the scene that will not end on cue.
