This step-by-step guide will show you How to Proceed Down the Tunnels in the Main Job: You Know My Name for the game Cyberpunk 2077 Phantom Liberty.
As the mission starts, head into the marker in the middle of Dogtown and force open the blue door. Continue until you reach the submerged tunnels, then dive into the water and advance.
Continue moving forward until you encounter an iron grill barricade, then turn left towards the red mine in the distance. The player can either get close enough to disarm the mine or stick to the right to bypass it
Proceed ahead and open the grated hatch located to the right of the first mine. Deactivate the second mine once you enter the hatch.
Unlock the red door of the van, exit from the rear, and then track the red cable up into the partially submerged room.
Go to the corner of the room and dive back into the water. Go towards the third mine, disarm it, then go through the hole beside it.
Head to the corner of the room, continue to swim through the narrow hallway type-path, and dive into the water again near the red cable.
Make your way to the third mine, disable it, and then proceed through the adjacent opening.
In the next area, open the shutter and enter the half-flooded room. Reach the submerged ladder behind the fence and climb up.
Climb the ladder then press the red break release button. Climb onto the lowered platform, then press the next red brake release button. Crouch to the next lowered platform and through the vent.
Climb the ladder, then activate the red brake release button. Step onto the lowered platform, press the subsequent red brake release button, and crouch through the vent to reach the next lowered platform.
Continue to advance further and then climb up the series of ladders to reach the top.
