Use the following trick to kills enemies easily if there are elevators or doorways in a room where enemies spawn. Normally when you exit through a such a doorway or stand inside or near the elevator, the enemies will leave and try to reach you by another route. This can be used to your advantage. When enemies appear in a room that is entered through an elevator or door, return to that elevator or door and wait until the enemies retreat. Use this time to heal or reload as needed. Slowly move out from the elevator or door until the enemies appear again. Eliminate some of them before stepping back over the space that will force them to retreat. You can also use Stasis on a single enemy before retreating, allowing you to kill it at your leisure. Note: This may not work in all locations, and will occasionally freeze or glitch enemies into ignoring Isaac.

Take the Semiconductor inside and it will malfunction and stop the electricity. Collect the Electro Shot mod access the terminal in the final room. You can also find a circuit behind the door that requires a wrench.
