Barricades

General#

Barricades are the blocks standing between a group of survivors and the things trying to reach them. Zombies break them by hand, humans patch them with cobwebs, and the whole fight over a room usually comes down to which side runs out first.

Breaking Through#

Zombies hold left-click on the barricade from within about three blocks. Step back and you lose your progress. You can only work on one barricade at a time, so switching targets throws away everything you have done.

Damage stacks with every zombie on the same block. Four zombies break a door four times faster than one, and a Tank counts as two by itself. This is the single biggest reason to push as a group.

Your XP bar shows the barricade's remaining health while you break it, and the block cracks visibly so everyone can see how close it is.

Break Times#

One zombie deals roughly four damage a second.

Barricade Health One zombie Four zombies
Cobweb 12 3 seconds Under a second
Glass 25 6 seconds 1.5 seconds
Dark Oak Planks 30 7.5 seconds 2 seconds
Mangrove Planks 33 8 seconds 2 seconds
Spruce Planks 35 9 seconds 2 seconds
Acacia Planks 45 11 seconds 3 seconds
Jungle Planks 50 12.5 seconds 3 seconds
Bamboo Planks 55 14 seconds 3.5 seconds
Birch Planks 60 15 seconds 4 seconds
Cherry Planks 60 15 seconds 4 seconds
Warped Planks 65 16 seconds 4 seconds
Crimson Planks 65 16 seconds 4 seconds
Oak Planks 70 17.5 seconds 4.5 seconds
Pale Oak Planks 75 19 seconds 5 seconds
Iron Door 150 37.5 seconds 9.5 seconds

Iron doors are worth twice the toughest planks and five times a pane of glass. Learning which rooms have them is most of what map knowledge is good for.

Repairing#

Hold cobwebs and right-click a damaged barricade. Each repair spends one cobweb and puts back 3 health, with a one second cooldown between repairs.

Two rules matter:

  • You cannot repair a barricade while a zombie is actively breaking it. You have to drive them off first, which is why a defended door needs someone shooting as well as someone patching.
  • You cannot take a barricade past its original strength.

At 3 health per web against 4 damage a second per zombie, one person with a full stack can hold a plank door against a single zombie almost indefinitely, and cannot keep up with three.

Repairing barricades counts toward a daily quest and a lifetime achievement.

Building Your Own#

Cobwebs are the only block you can place during a round. Crouch and right-click to place one as a fresh barricade rather than repairing an existing block. They are craftable from 2 sticks and 2 thread and drop constantly in common loot chests, so webs are the most renewable defence in the game even though they are the weakest.

Shears salvage a cobweb back into your inventory, but only while it is at full health. A damaged web cannot be recovered, so pick up your walls before the zombies arrive rather than after.

Blowing Them Open#

Zombies are not the only way through.

  • Grenades do more damage to barricades than anything else in the game.
  • Guns chip them. The Remington 700 is the best barricade-breaker a human can carry, while SMGs barely mark them.
  • Melee weapons do nothing to barricades at all.

Humans shooting their own barricades is a real hazard in a firefight through a doorway, and occasionally the only way back out of a room you sealed too well.
