Fallout: New Vegas

The stealth suit in X-13 is a very special piece of armor, but you'll need to pass the two stealth tests in X-13 to get the basic upgrade and please the Think Tank. This Old World Blues walkthrough will cover how to pass these stealth tests, how to kill the robot scorpions that invade the facility afterwards and how to pass the two optional stealth tests to fully upgrade the X-13 stealth armor.
