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. With the Courier's new shiny coil, head back down into the facility.

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 exits the facility, due to the fact that in addition to robo-scorpions, Y-17 trauma override harnesses may be waiting outside the main (lower) exit as well. If the player character utilizes a sneak skill of 100, heading towards Higgs village in order to fast travel may also become useless, as Lobotomites have a tendency to spawn there as well.
