The Past Within is a Co-Op Point and Click adventure set in the mysterious world of Rusty Lake. Both of the players will get to choose one of the sides between Past and Future. After selecting the side, both of the players will get to play the chosen side of the story. After selecting a side, the game will ask you if you trust the person who chose the other side, and then both of them will choose a picture between a bug and a butterfly. After choosing the same symbol, the first chapter of the game will begin.
In this guide, we’ll be covering the first chapter of the Past Within game.
Chapter 1
We’ll denote both of the players with the side that they chose. One player will be Past and the other player will be Future.
As the chapter begins, Future we’ll be looking at a machine similar to the computer. On the other hand, Past will have a letter on its left side and a box with 9 small buttons on it on the right side. Future needs to click on the Red Switch on the computer to turn the machine on and the screen of the computer will turn on. As the screen turns on it’ll say the “CUBICAL DEVICE 01BF” The Cubical Device holds a memory that contains the room of the person in the past. Now, make sure that you are in a contact with the other player because you need to communicate throughout the whole game to help each other and end the game.
Press the Enter key below the screen of the Cubical Device to go to the next screen and it’ll tell Future that you’re about to make a connection with the person in the past. Past will need to open the letter and read the date on the letter and tell it to Future. Enter the year 1926 in the machine to proceed forward. Now tell Past the flashing blocks on the screen so he can open the box. Confirm on the device that Past has opened the box and he’ll find the matchbox and then it’ll teleport to Future. Open the Matchstick to get the Switch.

Now Future needs to insert the switch on the left side of the device and turn it on. Click and drag it to the left side and insert the switch in P-17 and turn it on. Four pictures will show on the left side and Future will have to discuss it with Past to set the pictures in order. As a Past, go to the right side two times to see the four paintings on the wall. The correct pattern of the pictures is the following.
- Top Left – Crow Painting
- Top Right – Butterfly Painting
- Bottom Left – Tree Painting
- Bottom Right – Albert & Rose Painting
After putting all the paintings in the right order, Future will get the different symbols in the same positions. Past needs to click on the box on the ground in the same area as the paintings. Now, tell the symbols to Past so he can open the box. The box will open and Past will get coal and then Past needs to use the Coal in the fire pit. After using the coal in the fire pit, Past will get a diagram of three rows with 5 notches in each row above the firing pit. Now, Future needs to rotate to the back side of the device and he’ll see the same pattern that Past has in the diagram. Ask Past what he sees in the diagram to put the notches in the correct position. The correct positions for the notches are the following.
- 2nd Notch on 1st Row
- 4th Notch on 2nd Row
- 1st Notch on 3rd Row

After placing all the notches, a battery will come out of a small container on the right and the device will start to smoke up just like in the Past’s room. Grab the battery and insert it on the right side of the device. A small fan will start spinning and the smoke will start to go out through the fan. There’ll also be a timer showing above the battery, “17: 15”. You need to tell Past the time and Past needs to switch the area to the clock and set the time to “5:15”. The smoke from Past’s room will start to clear. Past needs to go to the Coffin screen and the picture of Albert will break down. Pick up the picture and Past will find a key.
Past needs to put the key in the second drawer to find the face mask. Click on the mirror and put on the face mask to equip the face mask and Past will see that his room turns snowy. Now, go to the double door with glass on them with different shapes and symbols. Future will find a key and a picture of when the fan started spinning so he needs to place the key under the small circle on the right side of the fan of the device. Insert the key and rotate it to open the circular frame and Future will see a shape that looks like an eye. Three different symbols will also come outside around the eye and Past needs to tell the positions of the symbols around the eye shape on the glass door on the bottom right of his screen.

When the symbols match, Future will be able to look through the eye and two shapes will highlight. Past needs to click the shapes and the symbols around the eye will change. Past needs to tell the positions of the symbols again to Future and after placing the symbols in the right positions, more shapes will highlight, and Past needs to click them. The symbols will change again and then they have to repeat the process until the door opens and they both will see each other. Future will see Rose wearing the face mask and Rose will see the device.
Past will find some papers on the right side of the cupboard on which the device is placed. There’ll be positions of switches in those papers. Past needs to tell the positions of the switches to Future. Future needs to rotate to the left side of the device and turn down the first two switches in the first row and turn down the second switch in the second row. A tape will come out and then Future needs to insert the tape into the device. After loading the tape, it’ll show Albert Vanderboom on the coffin. Past needs to go to the coffin screen and click on the coffin to see the name. Future needs to tell the flashing alphabet on the coffin and Past needs to click those alphabets to open the coffin.

Future needs to press the Enter key on the device to go to the next screen and it’ll ask the closest thing to Albert. Past needs to click on the front pocket of Albert’s Coat and get the code. Future needs to enter that code into the machine. After that, the machine will show three different substances: Bone, Flesh, and Blood. Past needs to place the orange triangle that he found in the coffin on the cupboard to unlock it. Past will find the same three symbols of Bone, Flesh, and Blood.
Bone
Future needs to go to the back side of the machine and 20 buttons will be showing. Past needs to pull the handle and he’ll find a tool that can be used to open the mouth of Albert. Past needs to place the tool in Albert’s mouth and then Future needs to tell the flashing position of the button and then Past needs to pull that tooth in Albert’s Mouth. They both need to communicate until Past gets the required tooth.

Now, Future needs to confirm the teeth sequence with the Past on the device to progress onto the net substance.

For the Flesh, Past needs to place all the candles and then place the diary in the Flesh section inside the cupboard. The candles can be found in the lantern hanging from the ceiling in different areas. Switch through the areas to find the candles and place them on the stand right next to the coffin. Light all the candles with the match stick and you’ll get a key from one of the candles. Use the key in the first drawer to get the diary. Place the diary in the Flesh section.
A screen will appear on the left side of the device. Future needs to tell the photographs to Past and the Past needs to fill one of the blocks with the pencil according to the emotions written on the right side of the blocks by Albert. The emotions will match with the pictures so both Future and Past need to communicate with each other. The blocks that Past needs to fill are in the following order.

It needs electricity to work so, you will have to place it in the vacancy of the Turbine. Make sure that the Turbine is also near the Fynbos Biome so, you can target it when the Solar Amplifier is installed.
Click the Solar Amplifier and then select the area of the Fynbos Biome to start a fire. After selecting the area where you want to start a fire, it will turn the Fynbos Biome and the near area of the biome into Ash Tiles and you will see certain tiles on which you will be able to place another tool named “Arboretum” Arboretum can be placed on the Husks of the burnt buildings and it will create a forest in its surrounding by using the Nutritious Ash Tiles.
