Defenders
Use this Barrier Mesh to stop attackers from getting onto site directly. This will make it difficult for attackers to get onto safe positions on A Site when trying to plant. You can hide behind Sign and shoot them as they try to break the wall or go around. This should also stall them long enough for your teammates rotated in Heaven to help as well.
Stand on the back wall in the middle of the tile shown, and put the top right corner of the Barrier icon at the tip of the tree and throw the Barrier.
