I am in chapter 5-1 now. I went a factory, I guess Ashley is in here. They took Ashley from me. When I get in here, my bullets finished after killed zombies. But Zombies are still coming and my bullets finished. Beat the those zombies is so hard for me. I cannot use knife for this. What can I do? Those zombies are really hard...
