Clinging to Memories 3 in ZZZ — walkthrough

Talk to Weisz/Belle, move along the only route through the cavern, collecting the gearlings, and stand on the "magnifying glass". Climb the blue lever to open the door. Go up to the second blue lever. You will be able to control two of Rina's banbus, Drizella and Anastella.

Stand on the first blue lever, then switch to the second banbus and stand on the next lever. Go up with both banbus. Collect the box on the right, go left and up, to the first blue lever. Go up and right with the second banbus, to the second blue lever (you can collect resources beforehand). You need to put a block on wheels on the blue lever in this room. Do not forget: when you push the block into the wall, you change places with it, that is, there are no dead-end or hopeless situations here.

Go to the exit with both banbus. Go up, pick up the observation data. Stand on the "magnifying glass". Move all the way to the right, climb up to the second observation data, collect the cogwheels and the Elite Researcher's crate just above. Fight the enemies and enter the portal.

Stand on the blue lever at the top, behind the conveyors, with one Banbu. Go through the open door with the second Banbu and stand on the blue lever. Go there with the first Banbu. Move to the right, move along the conveyors, collecting the cogwheels and activating the handle. You will turn the conveyor to the right. Switch to the second Banbu and go along the conveyors to the right. Activate the handle and go to the exit with the second Banbu.

Collect the supplies at the top and stand on the "magnifying glass" on the right. Stand on the blue lever at the bottom with one Banbu. Push the wheeled block to the right with the second Banbu, through the open door, onto the conveyors. Switch to the first Banbu located below. Stand on the handle on the right. Push the block with the top banbu again, and this time it will go to the right (due to the fact that you turned the conveyor). Push the blue block to the right to place it on the blue lever. This will open the passage from below. Move to the right with the bottom banbu, stand on the handle and push the block to the right.

Switch to the bottom banbu and stand on the blue lever on the right. Move the block to the last blue lever and leave the location. Move the only way, collect resources, including the latest observation data. Stand on the finish cell. Defeat all enemies to complete the task.
