Wall

"A basic barrier that is used to prevent passage through an area."

- In-game description

The first tier of player buildable wall defenses looks like a fence. The wall blocks movement, but bullets can pass through it. It can be upgraded to a Wall (Tier 2) by going into the "Upgrade Mode" with your Hammer, pressing  and hitting it with the hammer while having the required materials in your inventory.

This wall is fairly weak and can be destroyed by vehicle collision, heavy explosives, or precise heavy machine gun fire targeted at its edge.

The Tier 2 Wall is the most commonly found wall due to its good durability and low cost. Only Heavy Explosives can destroy these walls, but they are far less resistant than the Tier 3 version.

The Tier 3 Walls are very sturdy. It is recommended to use the most hard hitting weapons like Artillery and Satchel Charges to take one out. However, since the wall uses Concrete Materials to be built, it takes 24 hours to cure. Uncured Tier 3 Walls are far more fragile.

Tips

 * Walls and Gates of the same tier have the same health.
