Take out the fuse and re-load at the gift shop once more.

Kill all four (or five - too many body parts to count) stalkers and head upstairs. Power Node - Balcony near the corpse in the Stalker arena (after the battle). Wait til the charge, then stake (or stasis) and fire. Camp near the broken door, and wait with a weapon and a stake. To activate the stalkers, go to the center of the room after the door is destroyed and Isaac contacts Daina about an alternate route. Unlike some of the other Stalker arenas, this one has few surprises and just one way to get to you. Easily done on round 2 and onwards here (your ability to Re-Spec nodes can help you do more damage as well). Use the Seeker Rifle to kill a Stalker while zoomed in. While you can do this in Chapter 4 (the first instance you meet Stalkers), you may have a height advantage in the Chapter 6 stock-room (run back to the stairs and set some detonator mines to prevent them from coming upstairs). Kill a Stalker with the Seeker Rifle while zoomed in. Power Node - The admin office past the maintenance tunnel and slamming door. Take all the items you can carry, as you will get back into the hallway adjacent to the church lobby (and hence, the gift shop) shortly. There's a save station (due to the QTE death-scene), so save if you like. Stasis the slamming door and get into the security office. Schematic - Security Suit in the office storeroom near the hatch.

The necromorphs will appear once you step outside. Insert the circuit to unlock the door across the room. Solve the door puzzle by pulling open the panel near the dead guy in the mind-wipe machine and taking the circuit module to the circuit panel by the door.

You can either use a Javelin Gun to put down a spear (right under a vent or in the middle of the rooms is good) or simply juke/Line Gun or Plasma Cutter the suckers with some stasis. There's a reason for this, as two elite Slashers will drop in and attack soon after Isaac solves the puzzle to the locked door. Proceed to the brain-washing center and note the very large blow-out window in the room. Note you can break the fuse to unlock the door back to the church lobby (and hence the enemy free gift shop) to save, shop and upgrade. Smash through the enemies down to the ground floor and ride the elevator up to exit.
