Barricade

The three barricade levels a tile can have

Barricades are a core gameplay mechanic that allows for survivors to be safe on certain tiles while at the same time giving zombies incentives to clear barricades as it is a good source of experience (not to mention the juicy survivors full of loot that may be hiding inside)

Barricade Success Build Table:

# of Barricades	Survivors Enter?
<10	Yes
10-25	Yes
25-50	No
50+	No

Barricade build success rate scales linearly from 95% to 0% as you build from 0-250 barricades

Zombies have a base 50% success rate when attempting to destroy a barricade

Survivors can no longer enter a tile if there are more than 25 barricades and must enter using the parkour skill from an adjacent building

Zombies cannot enter any tiles that have a barricade on them
