Getting out of the Sinkhole in Control Resonant is quite hard because you not only have to plant all four probes, but also find a way out. However, you will also encounter some enemies of the Hiss, who are called Hiss. This guide will show you how to place the probes and defeat the boss.
How to Escape the Sinkhole

At the bottom of the Sinkhole area, you will see four probes lying randomly on the floor. Grab one of them and look at the minimap located at the top right corner of the screen; it will indicate the places where you can take the probe.

These are places above the buildings surrounding the area. The more you approach the place where the probe should be installed, the faster its light will blink. When you find the right location for the probe, its light turns green, and you should interact with the area to install the probe there. After that, move behind the probe and once again interact with it to activate it. Do the same thing with all four probes.
Escape the Sinkhole

When the four probes have been placed and activated, the diving bell will rise to a point beyond your reach. You will be confronted with a massive Hiss group, so eliminate all of them before you continue. Next will come the Hiss Ruiner, and you should stay away from it until it descends to the ground and stops.
Once it does that, climb onto it and hit the orb attached to it. The orb will cause serious damage to the boss. Once the boss has been eliminated, several platforms will come into existence near the Sinkhole, and you should use them to begin climbing.

Follow the glowing cord attached to the diving bell as you make your way through the area. This cord will guide you to your destination. After a while, you’ll find a spinning refraction, and you should wait for it to open, then move through it and reach the other side.

After that, the cord will be unobtainable, but there is a way to navigate further. You will notice several rooms up ahead, and while most of them have a yellow light around them, some of the rooms will have a blue TV. You need to go through the rooms with the blue TVs to find your way out.
Soon, you will reach a point with several rooms clumped together. Listen to the sound of the music to find the blue TV room. From there, jump up and look around to find a blue glowing area that will take you to the outside world.
