Defending Your Shelter Against Firefighters and Crawlers

Fortifying Doors and Fire Hazards

Firefighter variants completely bypass fire-based perimeter defenses and will break through standard wooden entrances. To keep your shelter secure:

• Avoid relying on surface fire barriers or lava moats as primary base defense, as Firefighters walk right through fire completely unharmed.
• Replace all wooden entrance doors with non-wooden alternatives or solid barricades. Firefighters are capable of chopping down wooden doors to breach your home.

Blocking Crawler Infiltration

Crawler variants introduce unusual infiltration threats due to their reduced size:

• Inspect perimeter walls, fences, and base foundations for any single-block gaps near the ground. Crawlers are able to squeeze through tiny one-block openings that keep standard zombies out.
• Completely seal floor-level gaps with solid building blocks. If a Crawler slips past your defenses, it will snap at your legs to slow your movement, making it difficult to flee from other approaching undead.
• Ensure external perimeters are well lit so you can spot low-profile Crawlers moving across the terrain before they reach your structure.
