Base Design vs Crawl-Out Zombies in 7 Days to Die 2.0: How to Fortify Against the Undead's New Tactic

The Storm’s Brewing update didn’t just bring tougher zombies and deadlier storms to 7 Days to Die—it gave the undead a new trick: they can now crawl through small (1-meter) gaps in your base. If your horde fortress hasn’t been updated, it’s basically an open house for zombies.

Whether you're a solo survivor or building with a squad, this guide will show you exactly how to upgrade your base to counter Crawl-Out Zombies—with proven block combos, layout tricks, and community-tested fixes.


🧟 What Are Crawl-Out Zombies?

With the 2.0 update, zombies no longer just smash their way in. Now, they:

  • Crawl through 1m gaps, including window slits, railings, and half-block walls

  • Can surprise attack from below, above, or side gaps

  • Crawl faster in certain weather conditions (like sandstorms)

🔥 Community Reactions:

“They slid right under my floor fencing and killed me during Blood Moon.” – Reddit User
“Old designs are dead. You need to rethink your wall layouts.” – Steam Discussion


⚠️ Base Types Most at Risk

Your base is vulnerable if it includes:

  • Bar windows or iron railings with no solid backing

  • One-meter openings between blocks or under roof edges

  • Unsealed crawlspaces, ramps, or decorative gaps

Even a single gap can become a zombie express lane.

🧱 Proven Base Design Fixes

✅ 1. Use Scaffolding Blocks for Vision Windows

  • Let you see and shoot out, but fully block zombie entry

  • Recommended for early-to-mid-game horde bases

✅ 2. Trim Gaps with Quarter or Pole Blocks

  • Fill small holes with narrow blocks like poles or ¼ plates

  • Zombies can’t crawl through but you still can melee or fire

“A pole + plate combo saved my bacon. Zombies can't crawl in, but I can swing through it.” — Steam Community Thread


✅ 3. Elevated & Suspended Base Design

  • Build 2–3 blocks above ground on stilts or spike trenches

  • Funnel zombies into specific access points

  • Especially effective during storm-based horde nights

“All my bases are now lifted with spike floors below—forces pathfinding into a murder hallway.” – u/BloodMoonBoom


✅ 4. Underground Safe Rooms with Crawl Traps

  • Create “reverse crawl zones” with tight tunnels filled with traps

  • Bait zombies into low-ground chokepoints and eliminate en masse

Pair with Molotovs, pipe bombs, or turret setups for full effect.


🔧 Tools & Block Combos to Use

🔁 Still Relevant: Classic Defenses

Even with the new AI, classic base strategies still hold up—if paired with crawl prevention:

  • Spikes: Still great for outer layers

  • Moats & trenches: Redirects crawler routes

  • Turrets: Now more useful with focused choke designs

  • Blade traps & electric fences: Best when paired with bar pathways

Pro Tip: Keep your entry stairs 2+ blocks wide. If one breaks, zombies won’t rush the walls!


🔬 Testing Your Base (Before Blood Moon)

💥 Use these quick tests:

  • Throw a rock into the gap—if it passes through, so can a zombie

  • Crouch-test it yourself—if you can sneak under it, fix it

  • Spawn a crawler in debug mode and watch pathing behavior


💬 Community Wisdom: Design Like the Dead Are Smarter

“Your base isn’t finished until it’s crawl-proof.” – 7DTD Wiki Contributor
“You don’t need to seal everything—just think like a zombie.” – Discord Survival Strategist
“Patch 2.0 made zombies smarter. Time to build smarter too.” – Reddit Discussion


🧠 Final Thoughts: Think in 3D

In 7 Days to Die 2.0, zombie AI now respects physics AND exploits gaps. The old days of thin bar walls and pretty overhangs are gone. Your new base must think in 3D—up, down, and through—to hold off the undead.

Use the tools in this guide, test your builds, and patch those weak points. The crawlers are coming... and they don’t knock.
