Make your way into Elliot Ludwig’s office. Inside grab the Daisy (1) statue from off the desk. You can also grab the Black VHS Tape (1) and play it in the nearby machine for some lore. Once you’ve done both look behind the desk and you will see a vent cover with handprints on it. Pull the vent cover off and jump into the vent.
Walk through the vent to reach a mechanical room. Inside this room you will encounter Poppy on top she will speak to you then move out of the way to reveal a electrical plug. Attach to the plug then wrap yourself around the two posts. Shoot your other hand to the second outlet to complete the circuit.
Once you’ve completed the circuit go back over to the vent you came from. Look up and you will see a grapple point that you can use. Use it to pull yourself up to the vent. Go through the vent and head out through the office back to the hallway.
