This page is about the cloned model that appears in the Fallout: New Vegas add-on Lonesome Road. For the original version that appears in Fallout: New Vegas, see ED-E. For an overview of eyebots in the Fallout series, see eyebot.
After the New California Republic's successful attack on Navarro, the NCR started searching through the Enclave's technology. While not understanding the purpose of one device, they recognized the symbols on it from those in the Divide and hired the Courier to deliver the package there. The Courier delivered it and left, after which the mysterious device started transmitting codes to the launch computers in the Divide, signaling them to detonate their nukes in their silos. The Divide was torn apart by earthquakes and storms and the device shattered. Afterwards, the computers of the Divide collected the fragments of the device, along with other scrap, and used them to make the frame of this version of ED-E.
At first glance the Courier mistakes the robot for ED-E, who plays music from the TV show "Ralphie". With an Intelligence of 6, the Courier deciphers the beeps and garble and realizes that the silo has "pretty advanced engineering capabilities", since it was able to remote-scan ED-E from the Mojave Wasteland and create copies within the Divide. If you do not pass this check, the player will still observe this, asking ED-E "So, you're like a robot clone?"
Upon joining the Courier's party, ED-E starts playing a log from Dr. Whitley, and continues doing so at certain "checkpoints" during their trip through the Divide. Ulysses will also use ED-E to communicate to you throughout the Divide. ED-E will also show through certain dialog choices that it misses Dr. Whitley and that it wants to be like Ralphie.
ED-E is one of the few characters to stay marked as essential in Hardcore mode because if he were to die, The Courier quest would become impossible to complete.
Immediately after you repair the original ED-E in Primm, the Courier gains access to the Lonesome Road ED-E's workbench and reloading bench, even before stepping foot into the Divide.
ED-E is one of the only two non-hostile NPCs that inhabit the Divide; the other being Ulysses.
If you turn on the general subtitles, ED-E's ending (composed of beeps) will be interpreted for you on the screen. The subtitles also translate in-game beeps, such as 'Sneaky beeping' when entering sneak mode.
ED-E can carry faction armor, unlike his counterpart in the Mojave.
One of ED-E's recorded messages explains what had happened during the Fallout: New Vegas trailer.
pc ED-E can be used multiple times in a row to repair weapons by exiting The Divide and entering it again but eventually he will stop repairing weapons for a while - even waiting for 24 hours doesn't help. [verification needed]
pc ED-E may not wait when told to, at first it may stay in place for awhile but will suddenly appear without warning following again. [verified]
pc On rare occasion ED-E will not follow you when you release him from the repair chamber. (To fix this activate a door you need to pass and wait twice,ED-E will open the door, but not follow you, then reload the last save and ED-E should act as normal) [verified]
pcxbox360 Sometimes talking to ED-E will give you the repair weapon option, even if your weapon is above 20%. Selecting this option will bring your weapon down to 20%.[verified]
pcps3xbox360 Asking ED-E to repair your weapon may cause him to stop following you. This is caused by an engine bug relating to script variables in dialogs, as one of the variables used to repair your weapon will overwrite the variable which tracks his waiting/following state.
pc ED-E can be restored to full functionality by entering the console command set "04004d16".waiting to 0
