Fallout: New Vegas Companion Guide

Much like in every other Fallout game, New Vegas introduces a number of recruitable allies. These poor schm... valiant souls will join you on your path of destruction through the Mojave Wasteland. Each one of these bullet sponges has a particular role in which they excel as well as a Perk that they give your character. As such, it's incredibly important that you pick your two followers carefully so that they provide you with the greatest benefits to your character build.

There are many different ways to utilize the followers in New Vegas. For example you could make a veritable firing squad by having Ed-E and a ranged attacker complimenting your own ranged attacks, or you could have Rex and Lily along to act as distractions while you snipe enemies from a distance. Or you could let Lily do all the melee fighting while taking shots along with Ed-E from far back enough that enemies never have a chance. It’s all about how you want to deal with the enemies in the Wasteland.

Mechanical Companions

The Mechanical allies you can recruit on your travels are somewhat limited with one that is suitable for melee and one that’s suitable for ranged combat. While they’re fairly powerful in their own way they’re also incredibly limited in that they cannot upgrade their weapons or armor outside of side quests. Unfortunately this means that they’re very likely to die on Hardcore mode if you aren’t incredibly careful about how you play.

Take note that you can indeed heal your mechanical companions with Stimpacks even if it doesn’t make sense. We’re looking at you Ed-E.

Realistically speaking it doesn’t matter which of these two characters is better than the other as you should pick one of them based solely on your gaming style. If you believe that your character needs ranged combat support than Ed-E is the choice while melee combat support means you’re taking Rex along. It’s about as simple as that.



Recruited from: Primm, Mojave Express Couriers.

Ed-E is sitting on the counter and must be repaired to get him to join up with you. You can repair him with a high enough Repair skill (65+) although using Science (55+) will make the Repair check easier. Or, if your Science skill is below 55 but above 35, you can fix Ed-E with Scrap Metal (3x), Sensor Module (2x) and Scrap Electronics (1x). These parts are scattered about and should be easy to find by just searching around.

Perk Granted

Enhanced Sensors: Increases the range at which the player can detect enemies. This is an incredibly useful skill for anyone who is using either the Sneak skill or planning on being a sniper. These sensors will pick up enemies before almost any of them have a chance to notice you especially when you’re indoors. While outdoors there is a chance that some rare few enemies will be able to spot you but this is the exception to the rule.

Side Quest

Ed-E My Love: This quest is surprisingly complicated to get started. Ed-E has a number of logs saved up inside of him and they’re unlocked after hearing certain keywords as well as time spent on the road. To start things off speak to Old Lady Gibson in Gibson Scrapyard in Novac about Helios. This prompts a recording saved within Ed-E.

From this point forward you need a mixture of killing time, such as by waiting or simply adventuring, and Ed-E hearing other key words. These words include Air Force Base, Archimedes, Eden, Enclave and Navarro. Speaking to Arcade Gannon in the Old Mormon Fort is a great way to get some of these as is simply traveling to Nellis Air Force Base. In either case after several of these logs the chance to end the quest will appear.

After this, wait for two in-game days and you should receive a transmission from Knight Lorenzo, who will direct you to Repconn Headquarters. On the top floor, loot the dead corpses to receive Brotherhood of Steel Mission Holotape, and Mission Statement XV-56.

Once equipped with those, go to the Hidden Valley and you should receive a message from April Martimer telling you to bring Ed-E to her at the Old Mormon Fort. If you do that, his weapons will be upgraded. Or, if you want an armor upgrade, take Ed-E to Knight Lorenzo. Note you must be on the Brotherhood of Steel's good side for this.


Ed-E is probably the better of the two robotic allies you can have as a follower. Since these guys can’t be upgraded the fact that Ed-E stays back while using his powerful laser blasts is something of a god send. For the most part he will hover near you until blaring his battle anthem and blasting any enemies who dare approach you. If you’re finding that he’s getting taken down too often tell him to hang back further so that enemies will have to run past you to get to him, giving you plenty of time to kneecap them.

When playing on Hardcore mode you will definitely have to protect Ed-E until he gets his armor upgrade. Keep him close by you so that enemies will have to choose between who they attack. Aim for their legs so it takes longer for them to close in and be sure to disarm them whenever possibly by going after their weapon arm.



Recruited from: Freeside, The King’s School for Impersonation

Must complete the “Nothin’ But a Hound Dog” side quest to get him to join. To unlock this you must complete the “G.I. Blues” quest and then speak to King again.

Recruitment Quest

Nothin’ But a Hound Dog: This is a simple quest but it bears note that there are several ways to end it. You need to bring a new brain to Henry for Rex and there are a number of options. Depending on what brain you pick you will modify Rex’s stats:

1) Speak to Old Lady Gibson at the Gibson Scrap Yard in Novac. You can talk her into selling you the brain of one of her dogs, Rey, for 700 caps. If your barter skill happens to be 70+, you can talk her out of said brain, giving it to you for free. Bring this back to give Rex increased damage.

2) Head west out of New Vegas to find the Violet and Violetta trailer park. Here you will find a Fiend named Violet with a pack of dogs led by Violetta. Kill Violetta and take her brain back to give Rex improved movement speed.

3) At The Fort you can speak to Anthony about Lupa. This starts a one on one fight with the vicious dog while you wield a machete. Using Lupa’s brain makes Rex able to endure more damage in combat. However, the Legion-hating Boone will refuse to travel with you when Rex is your companion.

Note that you can only receive one brain.

Perk Granted

Search and Mark: Having Rex around allows you to more easily find things lying on the floor as well as containers. By zooming into the environment you can see pretty much any free items lying about on the floor as well containers, safes, Hollow Rocks and dead bodies. This is useful but not really deciding factor in bringing him along.

Additionally, as noted above, Rex will receive different perks depending on which brain you chose:

* Rey's Brain - Faithful Protector (increase attack damage)
* Violetta's Brain - Unshakeable Tracker (increase speed)
* Lupa's Brain - Blood of the Legion (increase hit points)


Rex is a surprisingly vicious attacker that closes in on enemies rapidly to hit with weak, but constant, attacks that carry a chance of knocking his targets down. When he notices an enemy, and isn’t stuck in sneak mode, he will charge that enemy and attempt to knock it down over repeatedly while trying to chew its face off. Since he moves in so rapidly most enemies won’t get a chance to deal too much damage at range but he’s still quite vulnerable to powerful melee enemies, like Nightkin. If you want to keep him alive help him by disarming these enemies’s and then shoot them while they’re down.

While a strong ally Rex isn’t the greatest ally for Hardcore mode. All it takes is a Nightkin or two to land a few critical hits and say goodbye to your doggie. If you’re going to use him then keep him a good distance behind you in passive mode. This way enemies will have the chance to focus on you while he starts to knock them down.

    Boone is beast but hes boring and makes the game easy Veronica and Lily is beast with close combat... just give them a Ballistic fist and Oh,baby respectively and they will start pwning all ppl. in hardcore just dont use lily and set veronica on ranged energy weapons.. shes better with energy weapons then guns.. arcade is a looser cass is beast with shotguns raul is best with a revolver ed is better then rex
  • tylerwilson - August 2, 2011 3:37 a.m.

    yall need to know that if you do all the quests for the van graphs that (cass) rose casside will die
  • Jaborgia13 - May 1, 2011 3:51 p.m.

    God Head7 - If you don't get Rex the brain, after a while he dies, and if you get him a new brain his attacks are more powerful.
  • Jaborgia13 - May 1, 2011 3:49 p.m.

    Citizen Wolfie you need to work with Mr. House just for one mission and he will give you the Presidential Suite Key, and you can put companions in there to do that you have to say Lets Part Ways and then it will say something like make your way to the Lucky 38. The cool thing is, you can recruit every companion (Not at the same time) and tell them to go to your Suite, and then when you go back there, they'll all be waiting and you can pick whoever you want and you can take in turns, it also saves time by not having to go to there location and back all the time! Hope that helped!
  • luke26 - March 29, 2011 7:39 p.m.

    i was killing all the people in the hidden bunker and when i was running around ED-E picked up a zap glove and after that he was these shots of lightening and i don't know how to change it back.
  • godhead7 - January 27, 2011 11:52 p.m.

    Not sure if anyone else has done this but, if you get the quest to get Rex a new brain, but don't get hiim the brain, he will follow you around and you will have 2 companions. Makes short work of pretty much everything.
  • Taylor_griffin - December 11, 2010 7:52 a.m.

    This is the best thing to do get boone on your team give him the anti-material rifle and power armor with that this guy is f@cking invincible since the anti rifle kills almost everything in one hit and boone is a helluva shot
  • corruptuser33 - November 24, 2010 11:54 a.m.

    In hardcore Ed-e and Gannon as a healer or lily as a tanker is the way to go. You gotta do their quests though else theyll get mowed down. For Gannon you need power armor though else he's useless. I've tried all the other companions in hardcore and they all end up dying against mellee creatures like cazadors and deathclaws.
  • CitizenWolfie - November 6, 2010 10:16 a.m.

    Does aybody know how to get the companions to just chill out at your house? I'm trying to get them all and I read on GR somewhere that you can dismiss them and they will return to your New Vegas Suite but so far no such luck.
  • Ronimator - November 1, 2010 4:21 p.m.

    when i tried recruiting a second companion, the character said that i already have one, and that i cudnt recruit another, wtf ?
  • H2A2I00 - November 1, 2010 2:48 a.m.

    Veronica is my personal favourite since she just obliterates everything in her path and she proved to be useful against deathclaws surprisingly
  • EAC73 - October 31, 2010 7:08 p.m.

    I really like lily even though she does freak out but that is just what makes it fun to have her around especially when u go into inventory and give swap stuff with her she goes "grandma gots a present for you" its just priceless.
  • sniper430 - October 31, 2010 10:57 a.m.

    although I did not have the science to repair the robot on black mountain, isn't that also a companion? It was a mister handy I think...
  • McSpudds - October 30, 2010 4:26 p.m.

    Ed E's the best and he plays fight music when you battle with something
  • Gameguy94 - October 30, 2010 2:51 p.m.

    So far I really like Veronica. She's got really powerful attacks at close range while I blast away at range. I tried Boone for awhile but he's useless for CQB.
  • philipshaw - October 30, 2010 11:30 a.m.

    Great guide, I will check this out when I get back into Fallout: New Vegas next week
  • Darth_Griffin - October 30, 2010 4:29 a.m.

    it's worth noting (and you guys forgot to mention this) but ED-Es Perk also allows you to target cloaked enemies in VATS. Amazingly useful when going up against the Nightkin.
  • FnKaiser - October 30, 2010 3:29 a.m.

    Awesome, it might be also worth noting that ED-E and Boone are still essential (they can't be killed) on any difficulty with hardcore mode turned OFF, even after you complete their side quests. I'm working on getting all the companions then going back to my favorite little robot and a nothing-to-lose sniper.
  • Dabenguin - October 30, 2010 12:46 a.m.

    @manguy17 I did too Great article as usual
  • Manguy17 - October 30, 2010 12:42 a.m.
