Gun shooting funktioniert nicht

The game is built in a classic pixel style, and not only has three main modes of gameplay: storyline missions, survival, and defense for everyone to unlock challenges independently, but also comes with a large number of weapons, equipment, and character characters for you to unlock and use, A streamlined and delicate pixel wind scene, independently switchable primary and secondary weapon equipment, realistic simulated weather changes, and a highly textured shooting experience, complemented by slightly casual equipment cultivation and character unlocking, dedicated to bringing you a new and unique pixel shooting game experience.  Defense Mode: A large wave of zombies has rushed into the base, and you must pick up weapons to protect the last piece of land.  This game is a new and unique zombie themed action shooting game, with the goal of surviving in this zombie filled world.  Survival mode: You need to survive in various terrains.  Plot mode: Contains 40+levels, where you can clear zombies and pass.  It's too dark at night and you need to hide in a safe corner.  You need to escape to your destination and collect some items.  We need to search for supplies when we run out of ammunition.  Time is long, hungry and looking for something to eat.  The zombie is getting stronger and stronger. Good luck to you!
