You will come to a dead end, but you have to jump off the platform to the one below you, jumping over the railing just behind the broken bridge. Once you have the second orb, go back and go to the door on the right from where you found the first orb. The first orb will be right in front of you, while the second orb can be found by going through the door just behind you, via an orange bridge. Here, you need five orbs to open the door. To get to this phase you must use the orange boosters to move to the next segment of Ghostrunner. From there, follow the path once more, and you will get the final orb right in front of the front door, and it will also unlock. You must go down from there to the platform below to get the fifth orb. Once you have it, walk the path until you reach a place with an L-shaped bridge. Follow the path until you have collected four orbs. From there, head to the door behind you to get the next two orbs. The first orb will be right in front of you, as soon as you go down. In this part it turns out that the number increases so you need six orbs. Jump on the orange booster to get to the next segment. Once you have all four orbs, head back to the front door and it will unlock. The next two can be obtained by entering the two doors on either side of the front door. The first two are located on both sides of the bridge where the level begins.

This part of the challenge is simple, since you only need to collect the four orbs.
