Interior Wall
wall
Lighter wall used for room dividers and second-floor partitions. A bare wood frame is see-through and zombies can climb through it; a plastered wall is a finished wooden wall with a coat of plaster so it can be painted.
Variants
| Variant | Tier | Cost |
|---|---|---|
| Wood Frame | Light | 2 planks, 2 nails |
| Plastered | Medium | 4 planks, 6 nails, 1 bucket of plaster |
About the interior wall
Interior walls are player-built partitions used to divide rooms, seal off second-floor sections, and shape the internal flow of a base. Unlike exterior log or metal walls, they are built for layout and light containment rather than holding back a horde, so their main role is organizing storage zones, sleeping areas, and crafting rooms behind your real perimeter defenses.
Placement & defense tips
- ▸Use interior walls to create a small 'safe core' room deep inside the building where you keep loot and sleep, so a breach at the perimeter doesn't immediately expose everything.
- ▸Wall off open staircases on upper floors to turn a second story into a defensible retreat, leaving only one controlled approach.
- ▸Leave a doorway gap where you want a door rather than fully enclosing a space, since adding a frame later means tearing a wall section down.
- ▸Keep at least one interior wall between your safehouse and any exterior window or door so light and noise are less likely to draw attention through the outer shell.
- ▸Plan grid alignment before building; mismatched partial walls waste materials and leave awkward gaps you can't door over.
Choosing a variant
- ▸A bare wood frame won't stop anything, since zombies climb straight through wall frames; finish the frame into a proper wooden wall for any partition that needs to hold a zombie or block line of sight.
- ▸Plaster isn't a separate wall type: it's a finish you mix from plaster powder and water and apply to an already-built wall so you can paint it, so it only changes how the wall looks.
- ▸Since interior walls aren't your defensive perimeter, don't over-invest scarce nails and planks here, but do finish frames into walls, since a bare frame lets zombies through; plaster is optional decoration for when you have spare materials.
Common mistakes
- ✕Relying on interior walls as actual zombie defense instead of treating them as room dividers behind a real outer wall.
- ✕Boxing yourself in with no door gap, then having to dismantle a finished wall to add a frame.
- ✕Spending high-level carpentry effort plastering interior walls for looks while the exterior perimeter is still incomplete.
Frequently asked
Can zombies break through interior walls?
Yes, given enough hits any player-built wall can come down, and a bare wall frame doesn't stop them at all because zombies climb through it. Plastering is cosmetic and doesn't change that. Neither should be your primary line of defense.
Do interior walls block zombie line of sight?
A full-height wall blocks sight and helps keep zombies from being drawn to you through windows. Use them to hide lit or active rooms from the street side.
Is plaster or wood frame better for dividing rooms?
They aren't alternatives: build a proper wooden wall (frame first, then planks and nails), then optionally plaster it so you can paint it. Plaster is decoration only, and a frame on its own won't stop a zombie.
