Into the Sinkhole: Diving Bell, Probes and Exit

Descend with the diving bell
Use the bell’s upper control, stop for the Hiss encounter and press the control again after clearing the fight. The invisible enemies require watching the red lamps and their movement rather than attacking an empty marker continuously. Clear the later pair before continuing downward.
Place and activate four probes
At the bottom, carry each probe until its signal turns green, set it down at the valid location and use its rear panel to activate it. Repeat for all four. A placed probe is not automatically active, so check the panel if the objective still asks for a deployment.
Survive the extraction encounter
The bell moves out of reach while enemies arrive. Clear the waves and track the large flying Hiss. Use its low pass to reach its weak orb rather than trying to jump directly to the raised bell. Keep the arena in view so you can respond when the reachable opening returns.
Climb out along the cable
Use the newly formed platforms and the illuminated bell cable as your route. Wait for spinning refractions to open before crossing. Follow the television and music trail to the exit and confirm completion. Return to Power Lines if that parallel preparation mission remains unfinished.
