Damaged buildings offer less protection.

28th May 2008: Decay spreads through the ruined buildings of the city. The longer that a building stands ruined, from today onwards, the harder it will be to repair. And as the moss and lichens spread across the final few skylights, several types of buildings are now dark without a generator hooked up, reducing search and attack rates until power can be restored.

Decay

Decay is an ingame feature affecting buildings that have been Ruined. When Ruin was first introduced in August 2007 it was a fixed state, where all ruined buildings could be repaired for a single AP by any survivor with a Toolkit and the construction skill. However, it was widely argued that ruin was a waste of effort for many zombies, as it would take 5AP to ruin a building, yet only 1AP for it to be repaired.

The Decay update in May 2008 sought to remedy this, making decay a more realistic process. Any ruined building became increasingly difficult to repair as time went on, meaning that after a few days it would cost survivors more to repair a structure than it had taken to initially ruin it.

Rate of Decay

• AP cost to repair any building begins at 1 AP and increases by 1 each server midnight left ruined.
• As an example a building ruined for 7 days would have a repair cost of 7AP.

Repairs

Repairing a ruined building requires that all zombies be removed from it, and that the survivor has the Construction skill and a toolbox in their inventory.

• This is shown on the "repair building damage" button.

• In dark buildings AP cost for repairing the building is not displayed.^[1]

• It is possible that there is a cap on the maximum repair cost. However, none has been seen so far, with a maximum known repair cost of 577 AP.

Ingame descriptions

Any survivor with the construction skill can see the repair cost of a ruined building, (Dark buildings must be also lit) to see it's repair cost.

In addition to this the location description will change based on the level of decay. For instance a zombie standing inside a building that is where Small weeds and vines are beginning to grow in the dusty wreckage. can use the list below to know the decay level is 6 and the building will have a repair cost of between 32 & 41AP.

This information can be of use to differing groups;

• Scouting survivors can get a snapshot of approximate decay costs while scouting as a zombie.
• Zombies can see how long they have kept a building ruined.
• Newly spawned players can quickly see whether the area they start in is a long term Ghost Town that is best avoided at low levels.

Internal descriptions

The building has been completely ransacked, and has fallen into ruin.

1. A thin layer of dust covers the debris.
2. The wreckage is thick with dust.
3. Cracks in the ceiling have let the rain in, and rust and rot creep across the damaged surfaces.
4. The walls are damp and crumbling, with pools of stagnant water gathering across the uneven floor.
5. Mould and fungus blooms across the crumbling walls, and the building's fittings are buried beneath dust and fallen plaster.
6. Small weeds and vines are beginning to grow in the dusty wreckage.
7. The debris is thick with dust and weeds, and the walls are starting to collapse in on themselves.
8. Vines and lichen cover the floor and walls, and sections of the ceiling have fallen through.
9. The ceiling above you has collapsed, and a carpet of a thousand weeds reach towards the sky.
