Icebox

Use this Poison Cloud to create a oneway angle against enemies pushing through the left lane of B Long from Yellow. You will be able to see their feet in the left lane and they won't be able to see you at Yellow

Stand on the glass wall behind Yellow where the snow cracks, aim at the corner of the containers on the left, and move right until your crosshair is above the black and yellow stripes. Then move to the left side of Yellow container to hold the oneway angle
