Driving the vehicle into the elevator starts the Heisenberg fight, and once it ends the factory is gone for this run. Before you board, have File: Chris's Computer from the laptop, plus the B1 rows above (File: Sturm, File: Heisenberg's Diary, the Cigar (optional) and the Factory B1 Storage goat). If the Goat of Warding: Factory Elevator Shaft is still standing, it passes by again on this ride: watch the west wall of the shaft as the elevator climbs. Everything from the floors below the B1 door goes too, if that door hasn't already cut them off: Quit Hanging Around, File: Development Note 1, File: Development Note 2, the Goat of Warding: Factory Ventilation Duct, the Ball Mold, the Iron Horse Ball and the Labyrinth: Factory (Bister Skull), the M1851 Wolfsbane – Long Barrel, and the optional Locked Fridge: Generator Room Walkway, Locked Drawer: Private Passageway, Lockpick: Construction Tunnels, Lockpick: Operating Room, Treasure: Mechanical Part (Cylinder), Treasure: Mechanical Part (Shaft), Treasure: Heisenberg's Hammer, the Fenced stash: Large Power Regulator Room, the Treasure: MB3 crystal cache, the Treasure: Crystals by the Drill (Construction Tunnels) and the Yellow Quartz in the Large Power Regulator Room, the Materials Room, the Ventilation Duct and Walkway Access.
