Detailed walkthrough
When the Courier is first allowed out of the Think Tank and the Sink, the Courier will be tasked with retrieving three pieces of technology, and the coil from the X-2 facility is the easiest one to do. When the character enters the X-2 facility, there will be minimal opposition: Three protectrons. These three are spread out at various levels of the tower.

After defeating the protectrons, climb the ladder to the top of the tower and use the support arms of the transmitter to reach the X-2 antenna at the top. After grabbing it, the player will hear the scientists start to bicker again and Mobius will announce that the transmitter station has been overrun by his robo-scorpions. In addition to robo-scorpions, Y-17 trauma override harnesses may be waiting outside as well. With the Courier's new shiny coil, head back down into the facility.

When when the Courier re enters, a handful of robo-scorpions are now populating the building. The scorpions are tough, shoot lasers and will explode shortly after dying. Fast travel is useless when the Courier gets back outside, as a handful of scorpions will be waiting for the Courier the at the main (lower) exit.
