Raider attacks are a significant threat, especially in the early to mid-game. They enter through the vault door and proceed downwards, stealing resources and injuring dwellers. Strategy: Your vault door should be upgraded and have two heavily armed dwellers stationed in the first room (usually a Power Generator) directly below it. These dwellers should have your best weapons and high Strength/Perception. As Raiders move through rooms, drag additional armed dwellers into the combat rooms to provide support. Use Stimpaks liberally to keep your defenders alive. Raiders will eventually retreat once enough are defeated. A well-defended entrance is crucial for minimizing damage.
