X - 8 : High School Horror ! X - 8 : High School Horror ! is a side quest in the " " " Old World Blues " . After completing the quest , the player is awarded with the Spinal - Tapped achievement . Detailed walkthrough . The Courier should make their way to the X - 8 research center and use the terminal to the left of the locked door . Initially , there will only be the " Basic Institutional Data Test Retrieval " test available . The player character is required to collect three sets of data from the facility , as if they were a communist spy . Select the test when ready and make your way inside . Upon entering , the facility appears to be an American high school , created by Doctor Borous . Borous will guide the player through the loudspeaker , giving directions on where to go . First head through the right door , being mindful of the turrets that guard the halls . Go through the classroom door across the hall , and look for the terminal on the wall near where you came in . You can use this to deactivate the turret or reconfigure its targeting parameters . Opening the door in this room leads into the next classroom , where the player will find and a turret on guard . The terminal located on the teacher ' s desk will allow you to access the first data file . The next data file is in the Library , which is down the hall to the left . Make your way there and prepare to deal with the cyberdogs guarding the room . The terminal can be found in the far left corner of the room . If you use the sonic emitter to shut down the force field above the library , the turret above will fall and explode . Head through the exit on the opposite side of the Library , and look on the wall for the door marked " Stairs " . Head upstairs , being mindful of the turrets that guard the second floor . Accessing the terminal in the room will allow the player to shut off the turrets . Heading past the balcony and toward the gym , you will find the final terminal guarded by cyberdogs . Accessing this terminal will allow you to complete the test . Upon accessing the data , however , two cyberdogs will appear at the exit to the facility down the hall . Leaving the facility completes the basic test and opens up the intermediate test , which is the same test with added enemies . Completing the intermediate test opens up the final test , which will utilize force fields which cover doorways and increased security . Also , the locations of the data terminals will have changed . The player will need to have fully upgraded the sonic emitter to complete the final test . Completing all tests will complete the mission . Activate the terminal , and select " Residential Guard Test " . Go through the door , and you will enter into a large yard with several burial sites and Gabe , a very large cyberdog , who will then proceed to attack if he detects you . Glitches have been reported , in which the outside won ' t load upon opening the upstairs exit . The audio sample " Gabriel ' s Bark " can be found in one of the burial sites ; exactly which site is randomly determined when you enter the room . Be warned , especially if you have chosen to spare Gabe ' s life : obtaining the audio sample will cause four robo - scorpion s to spawn , attacking and quickly overwhelming Gabe without the player ' s intervention . If this route is chosen , the player will then have to flee from Gabe . Alternately , the player may exit the area before the robo - scorpions have a chance to kill Gabe . If you decide to kill Gabe , a timer will start counting down ( roughly 10 seconds ) . Just prior to the countdown reaching zero , he will detonate . The resulting explosion has a blast radius and damage that is roughly the equivalent of a . You still can loot Gabe after the explosion if you are fast enough . Dr . Borous will react differently depending on what choice the player makes here on whether or not to kill Gabe , though this has little effect other than changing a single dialogue option .
