Zoey fades through the shadows inside the container to avoid the barage, ending up behind it. She did hear Travis's question however, pumping her shotgun. She reached he arm through the shadow again, this time poking the barrel through one of the attacker's shadows, and fired. She couldn't see the result of the shot, but she assumed it would be fine since it was the guy's shadow. She then teleported behind a different container, more to the right of the ship, and switched to the UMP. Had she known this was her role, she probably would've picked up a rifle, but this would do.
