Billboards appear on many street blocks throughout the city (and on one car park) and provide a special surface for spraying graffiti. Unlike normal surfaces, billboards cannot be defiled by zombies and, therefore, tend to hold graffiti longer.
Unlike the city of Borehamwood (which has no billboards), there are 336 billboards throughout the city of Malton. Judgewood, Lukinswood, and Danversbank are notable for having no billboards, while Pitneybank holds the record for the most with a high of 10 billboards.
It costs 10 AP to tag a billboard and will always use the entire can of spraypaint to do so. Normal graffiti only costs 1 AP.
