Chinese Stealth Armor (Fallout 3)

The Hei Gui  is an armor originally worn by the elite Chinese Crimson Dragoon troops, as well as the Black Ghost counterinsurgency/terror units before and during the Great War.

The armor has active camouflage systems that, when the player is crouched, generate a modulating field that transmits the reflected light from one side of an object to the other, making a person much harder to notice (but not completely invisible). This technology was the basis for the unstable "Stealth Boy" wrist units developed in the U.S.

History
Chinese Stealth Armor was used during the Chinese invasion of Alaska and was the Chinese solution to invasion by U.S. forces in power armor.

Earlier Hei Gui models were also used during raids against the Hoover Dam secret laboratory and Limit-115 laboratory.

Appearances
The Hei Gui Stealth Armor was originally going to appear in Van Buren, the cancelled Fallout 3 by Black Isle Studios. It was the step up from UAF armor with its small stealth bonus.

It also appears in the Operation: Anchorage Fallout 3 DLC pack. It is obtainable from the sealed armory inside the Brotherhood Outcast Outpost once Operation: Anchorage has been completed. Once worn it will increase your Sneak skill by +15 and if crouching, will also apply a +5 stealth field which can be seen in 3rd person view. It can be repaired using Recon Armor. You are also allowed to equip any headwear. Any headgear that you equip will be invisible when you go into sneak mode with the Chinese Stealth Armor equipped.

Trivia

 * In Chinese, Hei Gui (黑鬼) literally means "Black Ghost". Literally, Hei (黑) means black, dark, etc., and Gui (鬼) means ghost, apparition, demon, etc. Usually it is used to denote a person of bad character. It should be noted that Hei Gui (黑鬼) has also become a racial slur against anyone who has dark skin in modern Mandarin slang.
 * The Hei Gui armor appears to bear a resemblance to the Cyborg Ninja armor worn by Gray Fox from Metal Gear Solid.
 * It also bears a striking resemblance to Raiden's "Sneak Suit" from Metal Gear Solid 2, especially when coupled with the optical camouflage.
 * The suit can be repaired using Recon Armor
 * The suit also has a striking identical appearance towards the main character's armour in the game Haze by Free Radical.
 * The stealth armor alone also looks somewhat like the armor warn by the stealth players online in the Splinter Cell game series.
 * Humorously the PC can equip head gear on top of the suit. Thus making it possible to enhance the abilities. Expanding on the that, it is possible to boost stats to their maximum using two of the same hat. Continually attempting to equip a hat of the same type that you are wearing will result in the bonus from the hat being applied, but the hat itself not being equipped. A practical example is the Roving Trader Hat which can be used to boost your Barter skill to 100 if you have two of them.

Bugs

 * Another bug is that the suit might not show the upper part of the head when worn.
 * A funny bug is if you have the Sandman perk and you use it while wearing this your character levitates five feet in the air without legs, while your head is going into a creepy shaking motion.
 * Giving this to companions may result in the armor disappearing from their inventory. They still wear it if they have nothing better but you can't trade back for it.
 * Giving this to companions may reveal an interesting glitch. Let your companion equip the suit. Crouch, and then stand. Then give him a better armor, so the companion will equip it. If you crouch again, you'll notice that the Sneak Field effect will still be there! You can even take the CSA away from him, give to other companion and do the trick all over again. The effect may disappear after a load, though. This trick can be done with all humanoid companions, except for Star Paladin Cross, since her standard armor is superior to the suit, so she won't equip it when you give it to her.
 * Crouching while wearing the Chinese Stealth Armor, and talking to Wadsworth, your robot butler in your house in Megaton( asking for a haircut) you will see a black background where your head will be in the haircut selection. (needs testing on PC version)
 * If you are standing up with the Chinese Stealth Armor equipped and reload. As soon as the reloading animation begins, go into sneak mode. The invisible shield will be active but your character will be standing and invisible for the moment. Once the reloading is done, you will go into sneak mode and still be invisible.
