Tips
  • During the alligator chase, precise movement is key. Stay on the left until it lunges, then move right, then back left.
  • When controlling Ada, the EMF Visualizer is crucial for progressing. Pay attention to visual cues for hackable points.
  • If you are in the danger state (unable to run very fast) when approaching the lift, consider reloading a previous save to avoid difficulty with the upcoming sections.
  • The ID Wristband is obtained in the Incinerator room, initiating a timed sequence.
  • ID Wristband
  • Large-Caliber Ammo x3
  • Handgun Ammo x12
  • Large-Caliber Ammo x5
