Buildings are items that gradually gain you more resources for buying more buildings/upgrades. Each building has an individual resource per second production and increase in price each time you buy one. Wall Destroyer currently contains 14 buildings, 6 of them being unlockable by purchasing specific upgrades. Each buildings damages the wall by giving cash/wall damage, except for the Brick Factory which only produces bricks. Reality Compromisers produces fourth wall bricks as well as attacking the wall. Buildings usually cost cash, but some of them require other resources.
Each building's price is calculated with the following formula, rounded to the nearest integer:
- where M = number of that type of building currently owned.
Or, equivalently:
Therefore, the cumulative price for N buildings is calculated as a finite geometric series:
The last 6 buildings requires specific upgrades to be unlocked. Each one of these upgrades are obtained by breaking one of the base walls.
