In Fallout: New Vegas for the PC, PS3, and Xbox 360, there are several companions you can locate that have varying skills and upgrades that may benefit you.
Here is the list of companions, what benefits they have, and where you can find them in the game.
Arcade Gannon
Arcade can be found in the Old Mormon Fort. You must have high intelligence or a skill level of 75 in speech to get Arcade join you the first time you see him. If you can’t recruit him the first time, complete Julie Farkas’ missions and he’ll join you after they are completed. Arcade has a skill called Better Healing which allows you to regain 20% more health from any source.
Cass
Cass can be found at the Mojava Outpost inside the Mojava Outpost Barracks. You must complete the “Heartache By The Number” quest from Cass, followed by the “You Can Depend On Me” quest from Alice McLafferty in order to recruit her. Cass has a skill called Whiskey Rose which gives you and Cass a higher damage level when you both drink whiskey. You will also not suffer intelligence loss from consuming alcohol, and you’re not effected by alcohol addiction. You can choose to give Cass the Hand of Vengeance, which increases her damage with all guns by 15%, or the Calm Heart which gives her +50 HP for more survivability.
Craig Boone
Craig can be found inside the Dino’s mouth guarding the town of Novac after 9 pm. You must complete the “One For My Baby” quest that he gives you before you can recruit him. Craig Boone has a skill called Spotter which automatically marks hostile targets in the area, and pairs very well with ED-E’s Enhanced Sensors skill. He is an excellent marksman, and can usually kill enemies before you even see them. After you complete Craig’s first quest, he will receive the 1st Recon Beret upgrade, which gives you +1 Perception and +5% Critical Chance. After his second question, you’ll be able to pick between the 1st Recon Survival Armor and the 1st Recon Assault Armor, which are identical except for looks.
ED-E
ED-E is a prototype eyebot that can be found in Primm. You’ll need either a skill of 55 in Science, 65 in Repair, or you’ll just need to find all of the parts in order to repair ED-E and recruit it. You can’t have ED-E and Rex as companions at the same time. ED-E has a skill called Enhanced Sensors which allow you to detect enemies at an increased range, and enemies will appear on the compass and can be targeted in VATS even while cloaked. This works very well with the Spotter perk from Craig Boone. You’ll get to choose between Enhanced armor or Enhanced Weapons when you complete ED-E’s quest.
Lily Bowen
Lily can be found in Jacobstown. Talk to Dr. Henry and complete the quest “Guess Who I Saw Today” in order to recruit Lily. Lily has a skill called Stealth Girl which improves the duration of Stealth Boys by 200%, and all sneak attack crits do an additional 10% damage.
Raul Tejada
Raul is a ghoul mechanic and can be found in a jail cell at the top of Black Mountain. Check out the first terminal to get a password for the second which opens the cell doors. You just need to talk to him in order to recruit him at that point. Raul has a skill called Regular Maintenance which slows down the degradation of weapons and armor. For upgrades, you’ll be able to choose between Vaquero which increases combat ability, or Full Maintenance which slows down the degradation of weapons and armor by 75%.
Rex
Rex is a cyberdog and can be found inside The King’s School of Impersonation in Freeside. You will either need to pay 500 caps or have a 60 Speech skill level to get past the door guard. If you choose to pay the 500 caps, you get them back when you talk to The King. You must complete the “G.I. Blues” quest given from The King, and then the “Nothin’ But A Hound Dog” quest in order to recruit Rex. You can’t have Rex and ED-E as companions at the same time. Rex has a skill called Search and Mark which allows you to find unequipped ammo, chems, and firearms within a short distance, as well as other hidden items like hollow rocks and safes when you are using the binoculars.
Veronica Santangelo
Veronica can be found in the 188 Trading Post near the Slop & Stop Shop. Veronica will ask you about the Brotherhood of Steel, so answer positively about them and she’ll join you. Veronica has a skill called Scribe Assistant which allows you to craft workbench items by speaking to her. She is also proficient in close combat.
