Barricades are any objects or structure that creates a barrier or obstacle to control, block passage or force the flow of traffic in the desired direction.
There are a few barricades:
-Riot shield(implemented soon)
-Wood shield barricade(implemented soon)
-Barb wire barricade(implemented soon)
So as the others are not functioning atm, lets head over to the brick walls.
There are two types of brick walls:
The long brick walls are a little bit longer than a human, and completely block your view.
Short brick walls are a little bit cheaper than long walls, and only cover you till your leg/waist.
More about barricades coming soon.
