Stealth Suit Mk II

The aural stealth suit Mk II, referred to by Dr. Borous as the psychoanalytic cardiac-dampening sneaky stealth suit, is a unique piece of medium armor in the Fallout: New Vegas add-on Old World Blues.

Background
Created by Big MT researchers in the X-13 research facility using captured Chinese stealth armor technology as a basis, the aural stealth suit was supposed to be a next-generation, cutting edge infiltration suit, to be used in the war effort. After the proof-of-concept suit was completed, work began in earnest on an actual prototype. While the first unit was merely a standard suit of armor, built to test the validity of the pattern, the Mark II became a unique, computerized platform, combining the best technologies available at Big MT.

The core element of the suit is an automated personality central control system located in the torso, which controls the built-in medical dispenser, capable of injecting Med-X and stimpaks automatically when needed, controlling the heartbeat of the wearer through a specialized cardiac regulator, providing real-time feedback on battlefield conditions, automatically fitting itself to the user's shape and frame and automatically adapts systems to the user's specifications during testing and unlock features as they come online (though since it never left the testing phase, the control system requires the user to complete infiltration tests in the X-13 research facility), based on an ingenious firmware upgrade created by the researcher Kael. These upgrades are necessary for the user to benefit from the more advanced subsystems, such as gloves coated with a rubberized dampening compound to enhance manual dexterity or advanced servomotor buffers in the leg rigs, allowing for faster sneaking. Along with firmware, the suit also comes equipped with its own subnet for discrete information gathering and transmission during missions.

In 2281, the suit, along with both the X-2 transmitter antenna array and sonic emitter, was integral to the Think Tank's aid to the Courier to take back control of Big MT for themselves from Dr. Mobius.

Characteristics
The suit has a similar design to the assassin suit, but is cleaner and has a luminescent white chest piece with similar white stripes on the back. The suit itself has a built-in medical system that automatically dispenses Med-X and stimpaks. A female on-board computer narrates the usage and current levels of these items, as well as warning of impending combat situations, reminding the wearer of an active Pip-Boy light, and making offhand comments without prompting. Should the user get poisoned by a cazador, the suit will dispense a stimpak if available and cure the poison. When the user is crippled while wearing the suit, the suit will dispense Med-X.

Upgrades
The suit can be upgraded in the course of four stealth tests in the X-13 facility. Bonuses from upgrades are cumulative.
 * Firmware version 1.1 - Adds a bonus of +10 to Sneak (Stacks with the +15 Sneak already on the armor, giving +25 to Sneak).
 * Firmware version 1.2 - Adds a bonus of +1 Perception.
 * Firmware version 1.3 - Adds a bonus of +1 Agility.
 * Firmware version 1.4 - Adds a bonus of +20% to Stealth movement speed.

Locations
It is found in three pieces in the X-13 research facility. One part in each of the three labs in the first hallway after entering the facility.

Behind the scenes

 * The on-board computer is voiced by Qore hostess Veronica Belmont, who also voices Light Switch 01 and 02, and the original unaltered voice of Christine Royce.
 * The AI on-board the suit is a reference to many assistant AIs from pop culture, including the AI of the motorcycle in the film Warriors of the Lost World; when the Robo-Scorpions attack, the computer says "Mean robot bugs! Mean robot bugs!" in the same cadence as the motorcycle says "Bad mothers! Bad mothers!"


 * Early versions of the scripting for the stealth suit Mk II still exist in the resources of Old World Blues, based heavily on the prototype medic power armor from Fallout 3. This includes the use of the special "Suit Med-X" effect specific to the prototype medic power armor, which would have allowed the stealth suit Mk II to apply Med-X without risk of addiction and with the added benefit of temporarily suppressing the negative effects of crippled limbs, as well as the negative effects of many types of addictions.
 * Opening the NVDLC03AuralStealthSuitQuest entry that governs the suit's unique features and dialogue in the GECK reveals that it was intended to have an "Advanced Optics" upgrade, after the v1.4 upgrade run. The Stage check for the v1.4 upgrade bark from the suit is set to 50, and the dialogue line for Advanced Optics is at 100, an invalid entry. Delving into the script file in the Quest data tab also shows that this would have been done in a VR test, likely the defunct VR room with the Protonic Inversal Axe inside before the entire test was scrapped for some reason.

Bugs

 * There is a bug where, after the suit auto-applies a stimpak, your health will not increase, keeping your health at the minimum threshold for the damage script. This causes the suit to use a stimpak every time you're injured, as you drop below the scripted HP, burning through stimpaks extremely quickly.
 * Before starting the stealth research in X-13, make sure all armor pieces are in your inventory. Starting the run before the pieces are taken may bug the script and result in not getting the armor.
 * The stealth suit seems to occasionally glitch out and continuously issue doses of Med-X until the user's supply has been emptied, or until the suit is taken off (Leading to Med-X addiction very quickly).
 * The suit can administer Med-X anytime the user enters combat or anytime the stealth status changes from [HIDDEN] to [CAUTION], even if no damage has been taken by the player.
 * When fully upgraded, it doesn't boost your sneak speed by the said 20%.
 * In third-person view, rotating to the front side of your character can sometimes cause the head and arms of the player character to disappear, immediately reappearing once the camera returns to the rear.
