Fallout: New Vegas Game Add-Ons (DLC) Hints
Where can I find the two K9000 mod upgrades?
1 of 7: Go a short way SW from the Big MT West Tunnel to reach the X-13 Research Facility, then go inside.
2 of 7: Work on the "X-13: Attack of the Infiltrator!" main quest (if you haven't already) until you enter the X-13 Stealth Testing Lab area.
3 of 7: Don't go downstairs to the testing room. Instead, go across the entry area and through the door that's next to a locked terminal.
4 of 7: Past it, go through the second door on the left, then go across to the NE corner of the room to find a technician terminal on a table.
5 of 7: Access the terminal and choose its second option to get the K9000 mentat chow mod.
6 of 7: Go back through the door, then turn left and go through another door.
7 of 7: Straight ahead from it is the other terminal you need. Choose its second option to get the K9000 resla roil mod.
