Orbitals Chapter 3 Walkthrough: Deep Matter Caves (Tri-beams)

After entering the asteroid at the end of Chapter 2, you will see two yellow markers, each leading to a different chapter. The left marker leads to Hearts in Unison, and the right marker leads to Tri-beams Combined. In this walkthrough, I am going to the right side first. You can go left first if you prefer, but the order does not affect the outcome.

Objective: Gain Access to the Asteroid Core

Your main objective is to gain access to the asteroid core. To do this, you need to activate all three energy beams. This is also your first sub-objective: Energy Beams Activated 1/3. One beam is already activated by default, and you need to activate the remaining two. Head to the right yellow marker to begin Tri-beams Combined.

Sub-Objective: Activate the Energy Beam

Head toward the right yellow marker. The path is pretty linear, so keep following it until you reach the destination. Park your ship.

Your next sub-objective is to pick up the Beam Cannon and the Liquid Launcher. Pick these up and leave the ship.

After leaving the ship, use your boosters to reach the airlock and enter the chamber ahead. Take a right and keep following the path since it is pretty linear. After a while, you will come across a blue machine with a droplet icon on it. Use the Liquid Launcher on the machine first, and then follow up with the Beam Cannon.

After that, head toward the yellow marker on the higher floor by following the green pipes. At the end, you will see a platform. Stand on it together, and you will fall down to the lower ground.

In front of you will be a flap with blue arrows on it. Use your Liquid Launcher on it. This will open a chamber where you can pick up a new tool: the Ground Pound.

After picking up the Ground Pound, head to the platform with the purple icon, and you will fall onto a machine. Use the Liquid Launcher to move this vehicle to the platform ahead. Once you have done this, get off the vehicle. A button will pop up on the ground. Stand on it and Ground Pound it.

After this, get on the second shuttle in this area. One player uses the Liquid Launcher to drive it, while the other player with the Ground Pound needs to jump on obstacles ahead to clear them. Once you dock this shuttle, another button will pop up. Jump on it again to activate it.

After this, follow the yellow cable and jump across the platforms to get to the other side. Here, you will find another shuttle. On this side, you will see three water icons and three push-up buttons.

Stand on a button first, then use the Liquid Launcher to lift the button up, and then jump on the button to activate one mechanism on the shuttle. Repeat this for all three buttons to activate all three mechanisms. Once all three are activated, the shuttle will dock.

Use the platforms to get back to the other side you came from. Ground Pound the button again, then use the water turbine and have the other player press the button on the machine to activate the beam. A cutscene will play after this.

Redirecting the Beam

Head back to the upper area and follow the yellow marker. Drop down to the lower level and keep moving forward, since the path is straightforward here. You will soon reach an open area.

You will spot a grey and yellow machine with a water icon on the bottom. One player needs to shoot the Beam Cannon at the reactor in front. This will activate a red beam that needs to be redirected. Use the Liquid Launcher on the mirror to redirect the beam, and then follow the direction of the beam.

Keep following the path of the beam. Here, you need to do three things in three different directions. Look to the first left. Use the Beam Cannon to align the platforms, and the player with the Liquid Launcher needs to get across the platforms to the other side and rotate the mirror to guide the beam onto the mirrors in front.

After this, get back to the center and align the drones again. Then use the Liquid Launcher to clean the mirror completely in front of you. Once the circle is complete, head to the right, align the drones again, and get to the other side of the platform.

Once on the other side, look to the right. You will see a channel that is clamped. Use the Beam Cannon to clear the path. Once it drops, start heading in that direction.

Keep following the yellow marker, but you will need to parkour and avoid the red beams in this area. Keep following the path and jump to the higher level. Once on the higher level, open the chamber.

A cutscene will play, which activates the first energy beam. After this, follow the yellow marker back to your ship and head out. Once you are back in your ship, Chapter 3 will end, and you will be heading towards Chapter 4.
