A bullet zipped across multiple zombies in one go, and it hit the shoulder of the special class zombie that they were chasing. But once that happened, the abomination of a zombie screamed and caused many regular class zombies to start swarming around it so that they could offer the protection that it sorely lacks. However, when that happened, Yinn was already one step ahead of her.
She used the headlights as a way to gain access to the special class zombie as she swung with the rope gun that each of them possessed. With that, the Grey Bear Squad Leader was swift enough to send another bullet into the zombie's head before she could deploy extra raven zombies to populate the night skies.
This was immensely crucial since they did not wish to attract any more attention by lighting the skies with bullet fire. Unfortunately, as much as they hope to keep a low profile, Click was not being subtle at all.
