One of the free stretch goals I received for backing season 3 of Zombicide was a set of two barricades. These are, at present, the only scenery items specifically designed for Zombicide. Barricades were introduced to Zombicide in the season 2 expansion set, Toxic City Mall. Barricades are represented in the game by double-sided tokens indicating their two states - "incomplete" and "complete".
To start building a barricade, a single Survivor spends 3 Actions at once. Place a barricade token, with its "incomplete" face showing, over a straight border of the Zone the Survivor stands in. An incomplete barricade has no effect on the game.
To complete a barricade, one Survivor may select an "incomplete" barricade on a border of the Zone he is standing in and spends 3 Actions at once. He then flips the token over to the "complete" side or replaces the token with one of the 3D barricades shown here.
A barricade can be completed in a single Turn if two Survivors spend 3 Actions each. The first Survivor spends 3 Actions to start it, then the second Survivor spends 3 actions to complete it. Note that all survivors who took part in the construction of the barricade earns 5 experience points. Also note that "Free" Actions can't be spent to build or finish a barricade.
1. Adjacent Zones are
set apart if their common border is fully blocked by any combination of
walls and barricades. Half street Zones and doors only need one
complete barricade to be blocked, but a mall double door and standard
street Zones need two complete barricade tokens to be blocked. A single
barricade in a Zone that needs two has no effect.
2. Barricades can't be crossed but don't block line of sight. You can shoot over them and Zombies can see over barricades.
3. Complete barricades aren't considered doors for spawning. They don't isolate rooms from the rest of the building.
A Survivor can entirely break a barricade in the same way he could open
a door. He still needs to have a door-opening weapon (Axe, Chainsaw,
etc.) in hand to do so.
5. Whenever Zombies get an extra
Activation (because of a card, miniatures lacking or another game
effect), remove all barricade tokens from Zones where at least one
Zombie of the indicated type stands. These Zombies spend their entire
Activation to destroy the barricade, even if they have several Actions
to spend. If a Runner gets an extra Activation that moves him into a
Zone with a barricade on his first Activation, he'll use his second
Activation to destroy the barricade.
6. The Zombies follow the
shortest route to the noisiest Zone or visible Survivor, as if there was
no barricade, though complete barricades will still stop them. They
pile there until a shorter path is defined or the barricade is
