To access the Fortnite “Destroy Control Points with a Stone Plow or Battle Bus” challenge, you must complete the “Connect to a device near Condo Canyon, Daily Bugle, or Tilted Tower” challenge.
The challenge we face is actually very simple: you will have to capture an armored battle bus or a car equipped with a stone plow, then break through the barricades of the IO controlled by a city level.
Where are the roadblocks located?
In all the cities under the control of the secret organization, you will find the barricades of the IO or whatever the Zeppelin stole. You can see them at the east entrance of Tilted, south of the Daily Bugle, or at Cone Crossroads. Roadblocks are strictly metal barricades marked with yellow triangles.
Where can I find a stone plow?
Stone Plows are the latest on-board upgrades added to Fortnite. they are objects Widespread It can be found on the ground, in chests, but especially in red combat boxes (boxes of such vehicles). Once in your inventory, throw it into the working machine of your choice to equip it with Stoneplow! You will be able to force IO barrages without any problem.
Another solution is to collide with an armored bus on these roadblocks, but there are only two examples: one at the shrine and the other at the synapse station!
