If you're an Abiotic Factor player searching for rare collectibles, the Unlost Sister Bobblehead is a must-have item. This guide will walk you through exactly where to find it, the best route to take, and key tips to ensure you don’t miss this hidden treasure.

Where to Find the Unlost Sister Bobblehead


Before you can grab the Unlost Sister Bobblehead, you’ll need to wait for the Sister of the Unlost to leave the Reactor entrance. Once she’s gone, the bobblehead will spawn in her place, allowing you to claim it.

Step 1: Starting at Level 1


  • Begin your journey at Level 1, marked by a large green "Level 1" sign and a map.
  • Move forward until you reach a yellow, tram-like structure (note: this isn’t a functioning tram but a passageway).
  • Pass through it and stay to the left, continuing until you find a staircase.

Step 2: Navigating to Spillway C


  • Take the stairs down, then turn left and proceed forward.
  • You’ll soon spot an orange balcony-like pathway—jump onto it and turn right.
  • Upon entering the next area, look to your left to find two staircases.
  • Climb the stairs to reach Spillway C, which leads to the Reactor zone.

Step 3: Claiming the Bobblehead


  • Follow the path into the Reactor room.
  • The Unlost Sister Bobblehead will be sitting on a table to the right.
  • Pick it up to add it to your collection!

Tips for a Smooth Hunt


Wait for the Sister to Leave – The bobblehead won’t appear until the Sister of the Unlost vacates the Reactor entrance.

Watch for Enemies – Some areas may have hostile NPCs, so stay alert.

Double-Check the Path – If you miss the orange balcony or Spillway C, backtrack to ensure you’re on the right track.

Why This Bobblehead Matters


Collecting the Unlost Sister Bobblehead isn’t just for completionists—it’s a rare item that adds depth to your in-game achievements. Whether you're a trophyhunter or just love uncovering secrets, this guide ensures you won’tmiss it.
