Scattered throughout the quarantined zone are various bunkers, often serving as safe zones or temporary shelters. Some of these bunkers offer unique challenges, such as timed zombie clear-outs, specific weapon-only trials, or survival modes against endless waves. Completing these challenges often grants access to rare weapons, powerful attachments, or large sums of money. They are a great way to test your combat prowess with each character and earn some of the best gear in the game. Look for NPCs near bunker entrances who might offer these challenges. Always ensure you're well-stocked on ammo and healing items before attempting a bunker challenge, as they can be quite demanding.
