Break Terrain in Howling Abyss

Certain structures in the map will break and fall in to the abyss after a certain action is done.

Dying near one of the statues on the bridge's sides might cause it to break or not.

Walking near the large pillar on the left side of the blue team's base will cause it to topple down.

Scoring a first blood will destroy another bridge at the leftmost side of the map.

There are a set of blocks near the purple team's outer turret that will fall when walking near it.

After losing a set amount of health, the turrets will begin to crumble. This can happen twice before being destroyed.
