hey so i got to do the task where you have to get to the reactor terminal, but i got to a point where there are like 4 sides and i dont know where to go, its like where theres an electricity orb wandering around, help please
In this task you should enable reactor attractors on the reactor terminal, then lure the core (wandering orb) into the reactor, which is placed in center of this chamber, using an anomaly sensor switched to attractor mode. (If you lost both sensors, there's another one in the gravity anomaly)
Then you can activate the reactor using the terminal, and proceed to the gates marked with large "C" letter. The gates can be opened using the terminal near them.
Service shop is the large hall with several derelict submarines and a large portal crane on on the ceiling of this hall.
There is two working terminals, one is controlling the crane, and second is used to start the software update when your submarine is in right position.
If you're completely lost, you can teleport to service shop using the cheats menu in the main terminal of the submarine. It's the 11th point.
