Once you activate all three, you won’t be able to leave until all three Vogels are finished talking.

The locations of the Vogel Ghosts are: directly behind the Speed Cola machine, on the right wall of the Challenge Room, and at the Aetherscope build table. Once you pick it up, you need to find three ghosts of Vogel and give them the book, these can all be activated at once, so you don’t have to worry about waiting until one is finished to complete the step. Vogel’s Journal at the computer, the item is glowing yellow and the word “Password” will be on the window in purple glowing letters. You’ll see another Dark Aether Portal going through it is how you start the next step, once you go through, go to the observation room above the Speed Cola machine, and pick up Dr.

The next step is unlocking the computer in the medical bay, where Speed Cola is. After collecting all the parts, go to the build table directly behind the Pack-A-Punch machine and construct the Aetherscope, this allows you to see ghosts in the Dark Aether and collect more lore for the game. You can also use this opportunity to go start on the Nova-5 upgrade for the Die Machine Wonder Weapon as some of the upgrade steps for the Wonder Weapon aren’t locked until you reach that step (If you want to know how to complete those parts, skip to Step 4, and come back). Once you pick up one part, Plague-Hounds will spawn and you’ll have to take care of them. You can find the three parts to the aether scope here: under the stairs in the starting room, on top of the crashed plane engine by Juggernog, and in the Particle Accelerator Room right behind the warp point. Activating the portal will send you back to the Dark Aether, so when you’re ready, you can activate the portal, this will spawn the three parts to the aether scope but the order they spawn changes based on what portal you have, so if its not in one spot, check another. There are 3 places that they can spawn, and they’re really easy to spot, those places are: behind the tank at Quick Revive, on the rooftop of Nacht Der Untoten, and the power switch.

Next, you’ll want to build the Aetherscope, which is in the Dark Aether, through another one of those portals, you went through to turn on pack-a-punch.
