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 (base 0.1 fourth wall bricks a second) 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.
Icon | Name | Unlocked at | Price | Description |
---|---|---|---|---|
Magic Mining | 1st wall destroyed | 1 brick | We need bricks to trade with the underground wizards for their secrets. Bricks are their most valuable resource. | |
Summon Titans | 2nd wall destroyed | 16 bricks | The wizards are willing to raise titans from the dead to help destroy the walls. This is a good idea. | |
Dark Magic Mining | 3rd wall destroyed | 6,666,666,666,666,666 cash 66,666 bricks |
Summons demons. Necromancers and titans do 50% more damage. We need to mine into hell with dark magic so we can make a deal with the devil to destroy the wall. Everything about this plan is excellent. | |

Unlocks reality compromisers. Unlocks the 4th wall upgrade tier. We have discovered with the breaking of the 4th wall that we are all inside a stupid idle game. Not even a real game! But we can use this knowledge to our advantage... | |
Black Research | 5th wall destroyed | 42,000,000,000,000,000,000 cash | Unlocks Black Obliterators. We have discovered a substance in [REDACTED] that holds more power than anything we have ever encountered. We call it The Black because it is pitch black. | |
Deep Magic Mining | 2nd wall destroyed | 66,666,666,666,666 cash 6 bricks |
