Level 11
Jump over two sections of the shadow when the platforms move on you. Then go up and jump over the upper parts of the same platforms to get to the lantern. Having done this, take the flashlight in your hands and climb with it to the first platform, which will drive up close to the second floor. Jump with the lantern down towards the second platform. Place the flashlight directly at the shadow of the second platform when it is as far away as possible (closer to the stairs) from you.
Run back and jump over the shadow that will go back. A shadow will pass by the lamp and you can pick it up. Climb up with the lantern and place it on the nearest moving platform, place it directly on the opposite wall (towards the corridor along which you must pass). Now you can easily overcome this corridor.

Level 12
Take the elevator up. Call the platform by pressing the red button and put the flashlight on the left on it. Moreover, the flashlight should not be directed in the direction of movement of the platform, but backward. Launch the platform. The lantern will drive off and will shine directly on you, lighting the way further. It remains to go to him and direct him to the exit.
Level 13
Go to the exit, but the corridor is littered. Turn right and behind the wall, on the pipes, you will find the first recorder. When you reach the next corridor, you will get the achievement. A lantern is hidden in a niche on the left. Take it and go to the big turbine. There is a remote control that allows you to rotate a broken screw. The screw consists of four parts, but two of them are completely destroyed. One of the two remaining allows you to move in a jump, and the other has only one piece.
Just on the other you have to put the lamp so that it now illuminates the desired part of the screw. Turn it and jump to the center. Turn the screw with another remote control and jump to the right. Use the second lamp to light the screw, press the remote control and take the first lamp. Direct one lamp in the opposite direction from the tilt, go there with the other and turn around. From a long distance you can cover a dark slope. Now go upstairs. Bring the first lantern with you to light up the path above. And you will find a second voice recorder before entering the ventilation.
Level 14
Get to the room with the screw. This time you can move along all four blades, and each leads into a corridor with a control panel. To begin, move forward and to the right, to the first lantern. Take it and put it on the edge of the nearest blade so that the lamp shines on the other end of the screw. Press the remote control so that the lantern on the blades shines in your direction. Jump to the center of the propeller and to the second lantern in the corridor on the right. Place it on the edge of the nearest blade. Thus, now two lanterns are located on the two nearest blades. Turn the screw so that one of the lights shines on you, and the other – to the left, where the first lamp was.
Move there; use the remote control to rotate the blades twice. One lamp will shine on you, and the other to the left, from where you came here. Get to the start. Turn the screw and pick up both lights. Set one lamp so that it illuminates the nearest blade. Install the second lamp on this blade so that it shines to the right. Press once on the remote control. You will see that the lantern on the blades now illuminates the climb behind. And you can go further. Take another flashlight with you, go up and light the bridge. But before him pick up the third recorder.
Level 15
Go down and Virgil will contact you. And you will receive the achievement. There is a lift on the right. Lower it, take a flashlight with you and go up. Point the flashlight at the blue button opposite. Lower the lift so that it does not interfere with the light. The same flashlight will illuminate the lower blue button, which will open the way further. Light it with the second lamp. Walk along the corridor and get the achievement.
Level 16
Keep moving. There is a button on the left. If you shine on it, a dark corridor with a second spotlight will open. Now it does not pick up. Go on the lift, get off and lower it by pressing on another remote. Stand on the top of the lift and ride on the third tier. Take the spotlight from here and go down to the first tier with it. Use one spotlight on the button, with the other – into the corridor with the third spotlight. Take all three spotlights and go up to the second floor. Take one spotlight to the third floor and light the button that opens the exit. Point the second spotlight to the button on the second floor, and illuminate the third way to the open exit.
Level 17
Direct the nearest lamp to the second one, on the right. Point it at the button on the wall. A neighboring corridor will open. Return to the first lamp and direct it through the corridor on the left to the button on the wall. Run to the second lamp and direct it to the first to illuminate the corridor. Again go to the first lamp, but take it only when you are standing behind, to continue to shine on the button. Follow towards the button. Turn the lantern at the button towards the corridor with a green arrow. Together with the first lamp, go along the corridor and shine to the right. Get out of here.
Level 18
In the next room, go right to the far lamp. If they shine on the blue button, the platform will begin to move. You don’t need it yet. Instead, position the lamp so that it faces the wall on the right. That is, if the platform moves off to the end, then the lantern will illuminate the same button. Shine on this button with the previous flashlight to get the platform to the other end. The first lamp will continue to illuminate the button and thereby hold the platform in this position. Take the second lamp that you just moved, and direct it to the second button to open the corridor to the platform with the first lamp. Jump there and grab this first flashlight. Stand back and set it so that it illuminates the blue button that opens the door, and the entire path of the moving platform. Follow to the abandoned lantern and carry it to the platform. Stand with him on this platform and light up the blue button.
The platform with you and the lamp will reach the other side, and the first device will illuminate the path. With one lamp illuminate the first, and the other – the second part of the corridor.
Level 19
The next room will be more difficult than the previous ones. There are three spotlights. Move to the second spotlight and point it at the rotating room. Having done this, return to the first spotlight and press the red button so that the bridge will rise nearby. Thanks to this, the second spotlight illuminates the button inside the rotating room, and the third – the way in. Bring the first spotlight there. Move to the second and raise the bridge nearby.
Go inside the rotating room and aim the first spotlight on the second. Bring the second into the rotating room. Point one spotlight at the button at the third, and the other let it light up the bridge on which you came here. Take the third spotlight and take it to the place of the second, directing it to a rotating room. Run to the place where the first spotlight was. Click on the red remote to create a bridge here. The door should be open, and the bridge should be lit. Take both spotlights to the first console (you will need to direct them at each other to illuminate the bridge). Then light yourself a passage to the exit.
Level 20
Take the spotlight and take it down to the second. Light the second spotlight without touching the button. Jump to it and put it on the platform nearby. Light up the button with the first spotlight so that the second spotlight rises on the platform. Partly you need to highlight the path to it. Get to the second spotlight, go up with it and light up the button behind the glass.
Due to this, the flap in the window on the left will drop. Run to the first spotlight, take it back to the corridor where it stood, but direct it to the window without a shield. Run to the second spotlight. Take it in hand, go sideways around the room, but at the same time continue to illuminate the button so that the shield does not block the path of light from the first spotlight. So you bring both spotlights to the exit.
One you light the door, take the other to it and install it on the side, illuminate the path for the first. Zoom into the first one and set it as far left as possible. Jump to the second one, which should be on the right by the door, and turn it a little to the right. Then again jump to the first and bring it closer to the left edge, a little closer to the door. The second point to the button in the wall to open the door. The first spotlight should be positioned at such an angle as to maximize the illumination of the corridor outside the door. And you can jump the rest of the shadow.
