Dead Frontier Night One Walkthrough
Here are some Hints to help you out.
Short controlled bursts! - Your ammo is limited so it's important to make every shot count.
Reload during pauses - The best time to reload is when there aren't many enemies about. When you notice a lull in zombies, hit the R Key.
Getting A+ - To get maximum points you will not only need to survive the night, but also make sure your overall accuracy percentage is high.
