Barricades

Summary
Barricades are a humans main defense against the zombie hordes. Humans can barricade any door or stairwell inside a non-ruined building to prevent both zombies and civilians from using passing through. If a door or stairwell is barricaded, players must either knock the barricades down, or use their climbing skill to climb over them. The level of reinforcing a barricade has is displayed by text such as 'lightly reinforced' or 'heavily reinforced'. Each of these damage levels determines the total HP on the stairwell or door, and how much damage it will take before breaking open and allowing players to pass through.

Doors
Citizens can barricade a door for 3 EP. Each time a door is barricaded, an additional 10 HP is added to it. Doors have a total of 12 different damage levels, with a fully reinforced door having 120 HP.

Stairs
Citizens can also barricade a staircase for the cost of 2 EP. Each time a staircase is barricaded, an additional 3 HP is added to it. Stairwells have a total of 8 different damage levels, with a fully barricaded stairwell having 25 HP.

Debarricading
Citizens can choose to unreinforce any barricaded door. The action costs 3 EP, and removes 10 levels of reinforcing. Alternatively, citizens can attack a barricade instead, potentially removing the barricade altogether. Be warned that such actions may not win you any friends from any citizens in the building, who are using those barricades for their protection.

Barricade Failure
For every zombie present on your floor, there is a 20% chance to fail any barricade action on a stairwell or door. This fail chance can climb up to 100% with 5 zombies present, making any barricade action impossible. A failed barricade does not cost the citizen any EP loss. It merely prevents them from completing their action.

Barricade Levels
Both door & stair barricades have a different amount of hit points that determine the total level of damage they can take before being destroyed. Each level represents 1 point of damage.
