Orbitals Chapter 4 Walkthrough: Deep Matter Caves (Hearts in Unison)

After completing Tri-beams Combined and getting back to your ship, your next sub-objectives are “Enter Gunner Seat” and “Enter Pilot Seat“, with “Energy Beams Activated 2/3“. Take your positions and start moving toward the left yellow marker.

Objective: Activate the Energy Beam

Keep following the yellow marker, as the path is linear. You will soon arrive at the airlock you need to enter. Park your ship.

Pick up your recommended tools for this chapter: the Scrap Hook and the Beam Cannon. Once you have both, head to the exit and use your boosters to enter the chamber in front.

Inside the Chamber

Once inside, start moving forward. In front of you will be a yellow crane. Use the Scrap Hook to get to the other side. Once the player with the Scrap Hook is across, turn off the conveyor mechanism so the other player can get to the other side as well. Once both of you are across, start moving in the direction of the yellow marker.

On the left, near the drill, you will spot some handles. The player with the Scrap Hook needs to pull out the handles to create a platform, while the other player keeps jumping across these platforms to get to the other side. Once on the other side, take the stairs to the upper platform and use the Beam Cannon to warm the icons in front of you one by one. This will pull out platforms for the other player to cross.

Go up the stairs and take a left to find a Train and Rec behind the yellow bends. After that, take a right from the stairs, and you will notice a door clamped by three hooks. The player with the Scrap Hook needs to pull the hooks out one by one, while the player with the Beam Cannon needs to wire-cut the circumference of the door. Once done, go through the door.

Oscillating Platforms

You will enter an area with drums and oscillating metallic platforms. Carefully reach the other side, watching the platforms’ timing. Once both of you are on the other side, use the trampoline in the corner to reach the higher level. Jump onto the center oscillating platform to reach the other side.

Music Puzzle

Once both of you are on the other side, keep moving forward. You will soon come across two platforms. Step on them together, and a chord will appear on the screen. Imitate the chord by shooting the utensils in front of you and matching the sounds. Once done correctly, it will open the door ahead. Start moving forward.

Dark Matter Puzzle

Jump onto the platform and get to the other side. You will see a drum in the center with two platforms adjacent to it. Each player needs to stand on one side. When the drum leans toward your side, use your tool to interact with the lever in front of you. You will need to do this multiple times until the dark matter is raised up sufficiently.

Stone Markers

After this, move to the next area. You will see three stones and three electronic markers. Match their signs. Once you do, three rocks will lift up. Climb on them and have one player pick up the broken part of the machine with the Scrap Hook, while the other welds it using the Beam Cannon. Once done, follow the marker on screen.

Piano Tiles Sequence

Keep moving forward, as the path is straightforward here. You will soon come across two buttons. Press them together, and a mechanism will activate, displaying the alphabet with symbols falling down. Follow the pattern. If you have ever played Piano Tiles or Guitar Hero, this section should feel familiar.

Once the sequence finishes, a cutscene will play. After the cutscene, move toward the yellow marker and press the red buttons together again. A cutscene will play after this, and the third energy beam will be activated.

Objective: Enter the Asteroid Core

Follow the yellow marker to exit this area, and another cutscene will play. Your next main objective is now Enter the Asteroid Core.

Head back to your ship using your boosters and take your seats. Head toward the yellow marker, park the ship, and pick up your recommended tools: the Beam Cannon and the Scrap Hook. Leave the ship and use your boosters to enter the asteroid core, completing this objective and starting the next chapter: Shattered Gravity.
