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.

Bugs
Beneficial Glitch - Infinite Headwear How To - Customize Visible/Active Headwear (when using glitch/exploit)
 * Certain NPCs can initiate dialogue with you even if they can't see you. Robert, from the Blood Ties quest is known to do this, as is the guard outside Allistair Tenpenny's suite.
 * The suit might not show the upper part of the head when worn.
 * 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. This also occurs if you have a Stealth Boy active.
 * 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.
 * Even though you are crouched, unmoving and invisible, enemies (especially Super-Mutants) may still be drawn to your location (PC Version). They may stand directly in front of you, waiting for you to react.
 * If you wear this with the Ghoul Mask the head of the armour will disappear.
 * If worn with nothing else equipped, the Chinese Stealth Armor may sometimes allow you to stack different head gears (with no upper limit), such as multiple different power armor helmets, or other miscellaneous hats and headwraps. After equipping the armor, you will be able to add a head piece just as you normally would, but when a second helmet is selected, it will not remove the first one. This is extremely useful if your character has a low damage resistance, as you can actually put on enough power helmets to effectively make yourself close to invulnerable (73 damage resistance seems to be the cap). This is also a fantastic glitch because the beneficial properties of unique head wear such as Three Dog's Head Wrap can be stacked, vastly increasing your stats. This glitch does not always work; sometimes you will not even be able to equip a singular helmet with the Stealth Armor in the first place. (Tested on X360)
 * Trying to equip multiples of the same helmet, such as two hockey masks or two outcast power helmets, will allow you to add an infinite number of perks that helmet has (not DR) because the first helmet will stay equipped while the second never gets equipped. For example, two hockey masks, the first is equipped and I get +5 unarmed.  The second, when attempting to equip, remains unequipped but adds to the perk, making it +10 unarmed.  And so on until you're done trying to equip the second helmet.  With this, I was able to have +2010 unarmed (hockey mask), +13 perception(any prewar hat), +130 big guns and explosives (raider blast master helmet), and +120 rad resistance (power helmet).  Granted, the cap for these are 100, 85 rad resistance, and 10 for perception.  However, even though unarmed says it caps at 100, continuing to add masks results in additional unarmed damage (I deal 150 damage with a Deathclaw gauntlet). (tested on X360)
 * Also it appears that after doing this switching to any other armor does not unequip the helmets, so you can go back to your favourite armor afterwords (but seriously what effects would you get from other armor that is beneficial after you have maxed abilities and stats and non-poison resistance, except for the stealth field), it may be possible to get infinite AP by using the re-equip buildup by using 2 ledoux hockey masks (needs to be tested. Tested on PC to be NOT working. Seems Ledoux's masks doesn't work with infinite headgear trick. You can equip many but only the mask's DR will be active.)
 * One of the main problems with the above glitch is that for the most part, it's fairly random which piece of headgear is selected as the "top" layer; the only one that takes damage when fired upon/smashed. For instance, if you are wearing three power helmets for their Rad Resist. but you are also in possession of the nearly indestructible Winterized T-51b Power Helmet, chances are that you'll want the T-51b as your top layer, protecting the other helmets on your person. To specify which helmet you want as your top layer, follow these steps carefully. You'll need the Chinese Stealth Armor in your possession for this to work, of course.
 * 1. Equip the helmet you want as your primary Damage Resistance headgear (best if it has the highest DR rating and/or CND).
 * 2. Remove any and all other headgear (glasses, masks, etc). Body armor will not affect this process, so it can be left as is for now.
 * 3. Save your game.
 * 4. Reload your saved game. This will cause the engine to reload your currently worn armor and appropriate 3D models.
 * 5. Equip the Chinese Stealth Armor and apply any and all other helmets you desire. If your helmet of choice becomes unequipped, simply put it back on.
 * 6. Equip any other armor you are going to wear, unless you intend on wearing the Chinese Stealth Armor.
 * 7. Exit your PipBoy. Your character's image should be preserved according to what you were wearing at the time of your last save. This also means that whatever head armor you had selected at the time will be the only armor taking damage, even if you are wearing multiple items.
 * This also has the enjoyable effect of allowing you to combine multiple hats and helmets in an interesting combination of visual styles, such as the Raider Arclight Helmet and a Power Armor Helmet for an even further retro-futuristic "robotic man" look, ultimately personalizing your character to an extent not normally possible without the use of mods.
 * The only limitation to this glitch is that you cannot equip more than one of the same headgear.
