Veins of Helios

Symbol #1: As soon as you exit the first airlock, turn left around the corner. The symbol will be on the wall directly in front of you.

Symbol #2: After exiting the first airlock, proceed to the end of the path. You will reach a point where you can use a jump pad or drop down a long chute. Hug the north wall while dropping down the chute and use your boost jump to reach the first level. The symbol is on the north wall of this level.

Symbol #3: From the previous symbol's location, drop down one more level in the chute. You should see an exit into the airless environment. Look east for a worker drone moving a platform with two holes. Jump onto this platform. When it reaches the far end, jump off the northern end onto another platform with a jump pad. The symbol is on the nearby wall.

Symbol #4: Go to the platform overlooking Central Maintenance, which has two jump pads. From this platform, jump onto the western of the three buildings surrounding the entrance to Central Maintenance. Go to the north ledge of this building and look south to find the symbol on the structure.

Symbol #5: Proceed through Central Maintenance and exit via the northern airlock (Airlock #3). Facing the airlock, go to the right ledge and look down to find some pipes. Jump onto these pipes, then jump onto the thin ledge of the eastern building. Follow this thin ledge around the corner, and you will find the symbol on the wall.
