Chinese Stealth Armor (Fallout 3)

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

The armor has active camouflage systems that, when activated, 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 canceled 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.

Trivia
In Chinese, Hei Gui (黑鬼) literally means "Black Ghost.", but it also has another meaning. Literally, Hei (黑) means black, dark, etc., and Gui (鬼) means ghost, apparition, etc. Usually it is used to denote a person of bad character, but can also be taken as an ethnic or racist slur.

Bugs

 * Wearing the Chinese Stealth Armor allows the wearer to infinitely equip headwear. However, only one of each item may be equipped, and DR does not stack (though skill and S.P.E.C.I.A.L. bonuses do).
 * 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 char levitates 5 feet in the air with out legs, while your head is going into a creepy shaking motion
