Walkthrough step-by-step
Into the Sinkhole is the fourth main mission in the Contain the Crisis questline and the second sub-quest of Notes: Plan of Attack. The active Pattern resonance the CFD needs can be found at the bottom of the Sinkhole and must be harnessed — the FBC team sent down to place the probe relays did not get far, so hopefully Dylan has better luck.
1. Escort the Probe Relays into the Sinkhole
The Sinkhole is in the Evacuation Zone and was passed on the way into the area the first time. Jump on top of the diving bell and interact with the button to start descending. After a short distance the bell stops and a room of attacking Hiss must be cleared; then jump back up top and press the button to continue downward.
2. Find and Defeat the Hiss
At the next stop there is a miniboss that turns invisible and hides in the room — spot it via the minimap icon and the red lamps that switch on nearby. When near its approximate location, attack around the area and you should eventually hit it. If healing is needed during the fight, run around the room looking for health pickups. After the first is defeated, another pair appears — defeat them too, then jump to the probe and interact with the button again to continue.
3. Install the Probe Relays
At the bottom of the Sinkhole, place the four probes that drop on the ground. Pick one up, then check the minimap (top right) for the destination — the relay spots sit on top of the buildings around the area. The probe's light blinks faster as you get closer and turns green when you are at the right spot; interact to place it. Then interact with the back of the placed probe to activate it. Repeat with all 4 probes.
4. Escape the Sinkhole
After all 4 probes are placed, the diving bell rises too high to reach and a large number of Hiss appears in the room — defeat them. After the first large wave, a giant flying Hiss appears; avoid its attacks until it floats near the ground and stops moving, then jump on its back and damage the orb there for heavy damage. After the boss dies, platforms appear around the area — use them to jump and climb back up the sinkhole. Keep following the lit-up cord from the diving bell to know where to jump. At the spinning refraction, wait for it to open and jump through to the platform that appears on the other side.
5. Follow the Music
At the top of the area, jump across to where the TV lights up in front of you; keep following the TVs playing music to lead you out, and once back outside the mission completes.
