People now use ladders to reach the rooftops in Sobek city Breakthrough

The rooftop nightmare is still not over for Sobek city.

Apparently people can still get up to some of the roofs in the second sector with clever use of the assault ladders...

So far the only effective way to I found to strike back at the  roof dwellers was to get next to the base of the building as a recon, deploy the drone, strap C4 explosives on the drone and to fly it to their faces (it quickly runs out of battery due to C4 and it explodes, detonating the c4 then it expires)
