Metal Wall

Overview
The Metal Wall is a building that can be placed by right-clicking with the building selected. In order to select it, click on its icon that is on the bottom right corner. It is just a wall with higher durability.

There can only be 30 metal walls at any given time which is owned by a single person, being the same as the normal wall. You can't put them in the borders. If one of the metal walls are broken, either by zombies or players, you will be able to place another one in its place.

Each of the metal walls cost $300.

Trivia

 * Its appearance is a group of metal merged together by screws.
 * It is referenced to as "Building1" in the game files, instead of "Metal Wall".
 * If you select the metal wall as an upgrade, you will not be able to place normal walls anymore.
 * The walls placed before you upgraded to the Metal Wall will stay as brick walls. until they eventually run out of durability. However, they do not count towards the total of walls, so you could theoretically place 30 walls and 30 metal walls at the same time owned by a single person.
