ED-E

"Eyebot Duraframe Subject E is both the prototype and the last functional model."

- Whitley

Eyebot (Duraframe) – Subject E (or ED-E for short), is a prototype eyebot and possible companion in 2281. Its armor and weapons are more advanced than regular eyebots.

Background
ED-E is an Enclave eyebot from the East Coast, built by Whitley at Adams Air Force Base. A prototype "duraframe" model, it has been enhanced for regular combat, as opposed to the original model which functions primarily as a mobile radio transmitter. However, the war with the Brotherhood of Steel necessitated increased production of Hellfire armor, and so ED-E was the only surviving model. Whitley uploaded an enormous amount of valuable data on Poseidon Energy and his duraframe research into ED-E's logs, then dispatched it on a cross-country journey to Navarro, past Rockville, Hagerstown, the Pitt, Dog Town, Nephi, Zion Valley, Caliente, The Hub, Necropolis, Lost Hills, and San Francisco.

ED-E's first stop was an unspecified Enclave outpost in Chicago for upgrades. ED-E then came across the Mojave Wasteland, where it was shot twice by an unidentified sniper, dealing quite a lot of damage.This eventually forced it to deactivate near Primm, where it was found and taken in by a courier of the local Mojave Express branch and given to Johnson Nash. Unable to repair it himself, Nash left ED-E to languish on his desk, where it remained when the escaped convicts took over the town. When the Courier arrives in Primm, they can repair ED-E, allowing the eyebot to join the Courier on their quest.

Though ED-E still retains all of its data and an understanding of its mission, its internal positioning hardware is badly damaged. The only reason it has not been seized by interested parties is because ED-E has not communicated its special mission to anyone.

Quests
ED-E My Love: Once ED-E's logs are discovered, the Brotherhood of Steel and the Followers of the Apocalypse will both express interest in it, offering upgrades in exchange for its data.

Other interactions
When first found in the Nash Residence of Primm, ED-E is broken and lying on a table. To fix it requires one of the following:
 * 65 repair skill
 * 35 repair with 55 science
 * 3 scrap metals, 2 sensor modules and 1 scrap electronics

Endings
At the end of the game any one of these endings will play but in the same beeping noise that ED-E "speaks" and so will not be able to be understood.


 * If ED-E remains forgotten in the shop of Johnson Nash, it is eventually repaired by another courier who lets it continue on its journey to Navarro. ED-E is eventually discovered by the Followers of the Apocalypse who manage to recover vast databanks of scientific knowledge.
 * If its logs are never cleared, ED-E travels with the Courier until one of its memory banks is triggered, causing it to continue its travels on to Navarro. Upon reaching Navarro, ED-E vanishes and is not seen in the wastes again.
 * If its logs are cleared and its systems are upgraded by the Followers, ED-E remains a vigilant and constant companion to the Courier. The Followers of the Apocalypse use the information recovered from ED-E on Poseidon Energy to develop new methods to harness the energy of the sun.
 * If its logs are cleared and its systems are upgraded by the Brotherhood of Steel, ED-E remains a vigilant and constant companion to the Courier. The Brotherhood uses the information recovered from ED-E to create a small army of Duraframe Eyebots.
 * If the Courier never returns to Primm to recover the upgraded ED-E, the robot is discovered by a traveling caravan, who take it on as a protector as they wander the wastes.

Appearances
ED-E appears in Fallout: New Vegas and on the cover of All Roads.

Bugs

 * If you tell ED-E to part ways and return to Primm, he may be removed from the game instead.
 * Exiting Bloodborne Cave may glitch ED-E to be stuck in the opening of the cave. Even with the latest patch, ED-E will instead show up as a marker, but can't be found in the surroundings or in the cave.
 * ED-E will get stuck in all the towers in Hoover Dam, mixing up what door to take to follow you. He usually ends up on the roof of the tower you exited. If you take the Elevator to Hoover Dam Offices he will usually appear. (After second patch)
 * ED-E is often rendered unconscious via explosions which make him disappear. This may also happen when ED-E sustains enough damage while already unconscious(tested using Knock-Knock and Holorifle on knocked-out ED-E). Often, ED-E is dead, despite retaining the Enhanced Sensors Perk and the player won't receive a message about his death. ED-E will still count as being a companion though, meaning that you won't be able to take Rex with you instead. You also won't be able to take Arcade Gannon with you if you encounter his bug where you won't receive a dialogue option to travel with you while ED-E is already a companion. More importantly, this bug will make it impossible to play the Honest Hearts DLC, as you cannot take companions with you into Zion. The same applies to the Boomer artillery bug below.
 * Boomers artillery will kill ED-E, even on normal mode and you will not be informed of his death.
 * When at Black Mountain, its possible that ED-E will disappear after The Courier is attacked by super mutants in the small pass with the bear traps and the large boulder, but only after the super mutants attack.[Confirmed]It can happen as well in the entrance of Vault 22.
 * When inside Vault 22 and you're tasked with lighting the gas to get rid of the spores from the spore plants, if ED-E is caught within the explosion he will fall to the ground on fire, and when you come approach him he will explode. The result is he will always be counted as a member of your party and will never be able to be let go even though he no longer exists in the game.[Confirmed]
 * If you hit ED-E too much when he's knocked out (even in casual mode) he might still die, though still counting as a companion.

Possible Fixes (unconfirmed)


 * This can be fixed by traveling to Vault 22 and using the elevator to travel to any floor if the quest involving Keeley has been completed. It is also confirmed that the Vault 22 elevator method also works if ED-E vanishes after you visit Lucky 38 and get the suite and the radar shows ED-E to be somewhere in Freeside.
 * ED-E can also be returned to Primm if you have the Dead Money DLC and you go there.
 * When ED-E disappears, you can attempt a 'fix' by entering the following series of commands into the console:
 * Then transfer everything that ED-E was carrying to yourself. This is very important, since the following sequence of commands will erase his inventory and return him empty:
 * (see below)
 * Not always required:
 * The refid is listed in the black box in the upper right hand of this page. It is typed without the quote marks. So a basic, non-upgraded Ed-E would be prid 001732d1. When the prid is properly entered it will return no dialog, just a new blank line (the name of the object and the ref id will appear at the top of the screen). You must continue to type the next commands on this line or start again from the beginning.

Other Bugs


 * When walking through many doorways, ED-E may become stuck and won't move unless you go through a door.
 * After upgrading ED-E's armor, its inventory weight goes up from 1 to 2. Traveling to the Fort and back with ED-E as a companion permanently adds an additional 2 to its weight EACH time you go there, eventually making it impossible to place items in its inventory anymore. There is no known way to remove this invisible item weight, and the only way to prevent it is by firing ED-E before traveling there. Telling him to wait elsewhere before going to the Fort still adds the extra phantom weight. Apparently, its laser is being duplicated each time your weapons are forcibly removed at the Fort. This does not happen at the casinos, though.
 * It is possible that getting the Followers upgrade will result in phantom weight being added when entering casinos.
 * If this bug happened on PC, you can using console command "removeallitems", this will reset payload weight to 1/210.
 * ED-E may, at random times, use the "Blue Plasma" weapon upgrade normally made available by completing ED-E My Love for the Followers of the Apocalypse. It is confirmed that the damage/critical bonus is applied. Rapidly clicking the Melee/Ranged combat button on ED-E's companion wheel during combat can also temporarily give ED-E the use of the upgraded weapon and also occurs when ED-E is damaged by explosives.


 * After upgrading ED-E with the Followers, if it is destroyed, the dialog & text about losing its perk after its death will not appear at all. You can lose ED-E without noticing its death in battles or Vaults if it strays too far from the Courier by its own way being in [DANGER] mode because of the hostiles around him. A related bug exists where if ED-E is destroyed, its perk still remains in the Courier's Pip-Boy and still fully working.


 * It may occur that ED-E will accept unlimited items if they are given to him in a single transaction.


 * ED-E delivers a message from the BoS after enough trigger words are activated. During the last paragraph of this speech, the speaker's dialect changes to that of a Hispanic male (possibly from one of the developers of New Vegas?), and the player is stuck without being able to bring up the Pip-Boy or move. The following speech made by the Followers of the Apocalypse will not play. Quitting to dashboard and reloading does not fix this bug, however entering via console seems to fix the problem on PC. You may also try telling ED-E to wait in a place prior to receiving the message and retrieving him later.


 * ED-E's weapon may sometimes appear to be floating in midair underneath it. To fix this, fire ED-E and follow it until it goes through a door to a new area. Go through a couple of seconds after it and it should look normal again. Then you can re-hire it. Quickest way to do this is to just enter a house and fire it there right in front of the door. Experienced with original and armor-upgraded ED-E.


 * If you tell ED-E to wait, and you go to certain locations, ED-E will randomly show up and rejoin your party (happened while in Vault 34 and on the "All or Nothing" quest), sometimes just through the next door.


 * FoA Upgraded Zapper lost in Casinos or randomly is two different weapons, Energy Zap(00166B94) and Electrical Zap(001694DF), can be restored with after using left-click on Ed-E while in console to target Ed-E. The ammo is not MCA, but energy cell(00078CC2), which seems to not get lost. This can also happen upon leaving Caesar's Fort location.


 * When ED-E returns to Primm after becoming lost, he will be hostile. If you have the Ranger Takedown attack and a Stealth Boy, there may be a chance ED-E will return to you as your follower. Allow ED-E to kill the people inside the store at Primm, then use the Ranger Takedown to temporarily knock down ED-E. Immediately after, use a Stealth Boy and crouch until hidden. Once hidden, stand up and repeatedly attempt to engage ED-E in conversation. If done properly he will start talking and you must then (Initiate companion protocol). Also, if damage has already been done to ED-E, and ranger takedown kills him, turn the difficulty up to give him more health, then try.(Confirmed on Xbox 360) You can do this to get ED-E back but if you're worried about ED-E killing Johnson Nash and Rudy Nash, you can complete this without them dying. Once you enter the Nash residence, let them battle it out and wait for them to run outside, ED-E will not follow (if he does he comes right back). If this does not work, keep loading the save from when you entered the Nash residence(assuming auto-save is enabled). Then you can deal with ED-E. Confirmed on Xbox360 after the Dead Money add on completed on Hardcore difficulty. On the PC, the easiest way to fix it is go to the console and type followed by . Then leave the shack, reenter and talk to him to get him to rejoin. Then type in  and  again to start the AI back up. It is also possible to recruit him before he turns hostile by activating VATS as soon as he is spotted, exiting VATS, and quickly engaging in conversation with ED-E.


 * Hostile ED-E seems fixed after Honest Hearts DLC complete. Had confirmed hostile before and left alive . Non-hostile when went back to Primm. Did not check after finishing Dead Money DLC.


 * Uninstalling the patch while ED-E is a current companion will cause him to no longer regenerate health. When he dies, it will not give you the message that he has and that you have lost his perk.


 * After quick traveling to Helios One, ED-E may become hostile towards Lt. Haggerty, which will cause any other companions to attack her as well. No other NCR soldiers around will become hostile if this happens. (Needs Confirmation)


 * If ED-E was upgraded by the BoS before the January 14 patch, it may also get the FoA upgrade after installing the patch, and it still randomly uses its previous zapper, giving it essentially 2 different weapons. This occurs even when not tapping the ranged/melee button in the companion wheel, I only occasionally accessed ED-E's inventory.


 * Sometimes when entering a casino and you choose to keep your holdout weapons, ED-E will only have holdout weapons when leaving the casino. Happened while doing The White Wash quest (Went in to interrogate Dazzle, left and ED-E lost all my weapons except .44 magnum revolver (Fallout: New Vegas) and the Silenced .22 Pistol)


 * (Maybe others) Sometimes upon returning to the Lucky 38 ED-E will fight with Cass.


 * ED-E May freeze in places sometimes, to fix this just talk to him or punch him to shove him, as he may be caught on some clipping. This should not make him hostile.


 * When at The Thorn (Near Westside), if you have ED-E wait by the edge of the platform where Lady Red is standing. After agreeing to fight in a match you are placed in the ring. When the gate opens, and you can attack the beasts, ED-E will attack from the platform.


 * When not in battle, you may hear the sound of crawling Giant Ants, or surging electricity. It seems that this sound is coming from ED-E.


 * When you give ED-E any faction armor, a notice will tell you he cannot wear that faction armor, and it will disappear.(It is also possible that the armor will appear on the ground underneath ED-E).


 * In some cases when you first get ED-E to join you the waiting option will not work until he is upgraded.


 * With subtitles on, if ED-E has lost a lot of it's health, the subtitles will say.


 * E-DE may sometimes be attacked by NCR troopers in Camp McCarran.


 * ED-E will sometimes not shoot at enemies attacking or enemies nearby, this can be solved by selecting the Melee/Ranged option in his companion wheel.


 * After ED-E has been upgraded by the FoA, he may not be given the 'Blue Plasma' weapon. [Confirmed on 360].


 * It is possible for ED-E (after armor upgrade) to not use his weapons and even not move out of place, If you fast travel or wait he will rejoin you.


 * When sent to the BoS they may empty ED-E of any items he may be carrying prior to the upgrade causing you to lose anything he had.
 * It is possible for ED-E, after receiving the Brotherhood upgrade, to glitch giving him both upgrades (it is not confirmed whether he receives the upgraded weapon or the color and sound of the weapon simply changes without any added bonuses).
 * After ED-E is upgraded by the Followers he will continuously switch weapons in combat.


 * Maximum Hit point drops to 50 with no reason.


 * If ED-E has anything in it's inventory all items in the inventory will disappear After it is upgraded by the FoA.
