i play from the see wall, theres a spot on that catwalk on the far side of the map, and then i like to work from the rocks on the side of the base

the catwalk spot is nice cuz you crouch down in a shadowed area ... most players dont catch where you are right away

honestly, as long as i stay out of the open space by the front of the base i do excellent, i get out in that open area and i lose bearings quickly
