X-8: High School Horror!

X-8: High School Horror! is a main quest After completing the quest, the player is awarded with the Spinal-Tapped achievement.

Detailed walkthrough
Taking place at the X-8 research center, the quest has two parts. For the first part, the Courier needs to start and complete the "Institutional Data Retrieval" basic test, while the second part requires taking the "Residential Cyberdog Guard Test."

Once inside the research center, turn south and head down the stairs to find a room with coffins and three floating brains. Approach the "X-8 Test Terminal" next to the locked metal door with the "Testing Areas" sign above it. From the terminal, select "Enter Institutional Data Retrieval" and then select the "Basic" test. Then enter the test facility through the now-unlocked door.

Institutional Data Retrieval
The facility is an American high school, created by Doctor Borous, who will comment on the Courier's progress through a loudspeaker. Enemies encountered here are cyberdogs, "Hall Monitor" automated turrets and lobotomites.

Head through the southern double door into "Hall H" and enter into the first classroom on the right. In it, find a wall-mounted "X-8 Turret Control System" terminal in the northeastern corner of the room, with which the turret in the next room can be manipulated.

Continue through the southern door into a large classroom, access the terminal on the desk and download the first student report from it. Exit the room through the northern door and continue north, past the door into the library. Inside, find another terminal in the northwestern corner of the room, and download the second student report from it.

Exit the library through the northeastern doorway, past the small kitchen area, and through the northern door with the "Stairs" sign above it. Go up the stairs and take the southern door to enter the library's second floor. Follow the path to reach the double door in the southwestern corner, and enter the hallway behind it. Turn west for a short distance and enter through the doorway that reads "Coach's Office." Inside, find another terminal on a desk in the southeastern corner, which holds the third and last student entry. Once obtained, leave the office again and exit through the eastern metal door at the end of the hallway.

From here, head north through the metal door and follow the path until reaching a red exit sign. Exit back to the main facility through the nearby metal door.

Residential Cyberdog Guard Test
Back in the main facility, access the "X-8 Test Terminal" again, select "Enter Residential Cyberdog Guard Test" and go through the metal door once more. This time it leads into a large cavern, home of Dr. Borous' former pet cyberdog Gabe. The goal is to obtain the Audio Sample - Gabriel's Bark holotape from one of the six earthen mounds labeled as "Gabe's Digging Spot," the mount holding the item is random every time.

The digging spots are located as follows:
 * Upon entering, head east past a small fence with some metal crates, the spot is slightly to the left.
 * Turn south to find the second spot next to a support beam.
 * Turn west to find the third spot next to a massive rock pillar.
 * Turn slightly northwest to find the fourth spot next to a long piece of fence on the ground.
 * From here, find the fifth spot to the southwest nearby, or the sixth spot to the northwest behind the house.

After retrieving the holotape, several robo-scorpions spawn near the exit, and the quest concludes.
