There are a few options for starting positions here. Smoke and Lesion can start in Warehouse and fall back. Smoke should play a shield in Missile holding a line of sight into Warehouse. Lesion can play in Barrels/Electrical, falling back into Lockers, and then Lab. Skopos should plant a drone second floor for flanks. The other defenders can sprawl to fill out the basement. Rotate as needed to support each other to meet the push.
