This section contains a complete walkthrough for The Inferior World chapter in My Memory of Us. Here you will find a thorough walkthrough for Chapter 9 with screenshots. With this guide to My Memory of Us you will easily beat the game.
This chapter is mostly a chase sequence. Don't allow yourself to lose speed on holes and branches on your way. Avoid cars, signs, chests. Try to use speed ups (example is shown below, the speed-up field is marked with red arrows).
Once you reach the destination, go to the right until you encounter two guards. There is a chain and a platform with paint between them. When the guard on the left turns away, pull the chain a few times.
After spilling the paint move further. On the left side you will see another memory. Keep going to the right and enter the alley leading deeper into the location (it's on the right from the old lady in the window).
Keep going. Jump over the chests and get to the end of the street. Then, go deeper into the level. Pass by the guards and go down to the next alley. You should reach the place shown in the picture below. This person will give you a radio.
Now go back to the previous alley. You will notice that the robots don't tolerate having a radio. Wait for the robot at the top to move away, climb on the upper platform and hide in the pipe in the middle. Once the guard passes by you, leave the hideout and go to the left. Press the button and go down the ladder. Go to the alley located below and then to the alley that is even below. Now you must sneak pass guards - it is recommended not to use stealth here because you might not make it in time. You must use the moving vehicles as cover and go to the left. Start running a bit earlier before the car, so that you will be sure that you can pass by the guard. The cars are faster - you can't move through the whole alley by using a single car. Use the gaps between the guards to wait for another car. In one spot you will find a pile of boards. Take the advantage of it to rest before continuing to avoid the guards. Keep going to the left, place the radio near the painter (on the drawer next to the easel - check the picture below).
The painter will leave a brush - take it. On the same level, on the right, you will find a bucket of red paint and a painting of an important person on the wall. Use the brush on the paint, walk towards the painting and interact.
In this minigame you must match proper patterns to the marked spots on the painting. Don't worry if you make a mistake - there is no penalty for a mistake. Keep filling the areas until there are no more red patterns available. Then, take the painting, hang it on the first hook (the one near the bucket with paint) and use the knob. This should distract the guards on the further plane. Take the radio from the painter, go up and then to the left.
In this place you must interact with the child cart - the man will help you transport the radio next to the guard. Walk with him and then take the radio. Go up and then again up (to the left from the old lady in the window). Place the radio on the shelf. Now you must transport bricks for the workers twice - deliver the cart with bricks to them. You must fill the cart in the place marked with arrows on the left side. A pipe is hanging there, there is also a button that sends the bricks. Take the radio, sneak pass the guard, go to the right to the point marked with arrows. Now you can receive the secret code with a radio. Each number is a different symbol.
The access code to the door is: 715. Now go back to the location with the old lady in the window. You will notice a man on the right side - he will unlock a passage for you. Keep going to the right until you encounter the girl.
