Fallout: New Vegas companions

Companion wheel
The companion wheel is a new feature that is added to Fallout: New Vegas. The wheel provides easier control over non-player companion characters in the game.

There are 8 sections on the wheel, each with a specified function.

The available orders are:
 * Toggle melee/ranged fighting - also displays the weapon they are currently using when highlighted. Also if you instruct a companion to change their combat style, they will make a comment hinting towards the best combat style for them.
 * Open inventory - This displays the companion's current inventory, inventory weight, and weight limit. Be advised, however, as it appears that not all companions can carry just anything: ED-E and Boone, for instance, will not carry Legion armor of any kind.  Instead, any Legion armor the player tries to give either of them will simply be dropped on the ground.
 * Toggle stay close/keep distance.
 * Back up - makes them back up a few yards.
 * Toggle aggressive/passive AI. Aggressive means that they will any attack enemy on sight, whilst passive mode means that they will wait until you enter combat. This is very handy when sneaking around places with lots of enemies, as they will hold back on a [Caution], and wait until the enemy has properly engaged you in combat.
 * Use stimpak - heals your companion, and also shows current health.
 * Toggle wait here/follow me.
 * Talk to your companion with the regular dialogue boxes. This also provides an alternative method of giving orders to your companions, but somewhat redundant considering you have to use the companion wheel to get to dialogue mode in the first place. You do need to go into this mode to be able to dismiss your companions, however.

Nerve
Each companion also has a special attribute referred to in the game as Nerve. Nerve grants a total bonus of +50% damage and damage threshold to companions with a perfect charisma of 10 and only +5% to both at the minimum score of 1. A person with a starting charisma of 1 can boost their companions nerve to the maximum by use of an Empathy Synthesizer or Intense Training, Party Time Mentats (+5) and high Survival (so that alcohol adds +3 charisma).

This is most effective with companions that gain increases to their damage or damage threshold upon completion of their companion quests and less important for companions who gain items or abilities not associated with nerve.


 * Rose of Sharon Cassidy - Hand of Vengeance
 * Veronica Santangelo - Bonds of Steel
 * ED-E - Brotherhood Examination (DT+8) or Followers Examination (+??% Damage).
 * Rex - Rey's brain

Faction Armor
Permanent Companions will refuse to wear or even carry faction-specific apparel, except apparel corresponding to their preferred faction (see Exceptions). Giving invalid faction apparel to a companion will result in that Companion immediately dropping the item (see bugs); it is not returned to the player, but must be picked up from the ground.

This limitation does apply to non-human Companions who cannot wear armor, i.e. Lily Bowen, Rex, and ED-E. Giving these Companions any faction-specific apparel will result in them dropping it, as described above.

Although a temporary companion, Primm's Deputy Beagle is subject to a similar restriction, and will not accept any Powder Ganger apparel given to him.

Exceptions
Some Companions can be considered to be already allied with or accepting of certain factions, and as such will carry and/or wear apparel specific to those factions.

Although these Companions will wear some faction-aligned apparel they are not subject to the same effects, namely they are not treated as being disguised as a member of the faction in question.

Boone
As a former member NCR 1st Recon, Craig Boone will carry or wear any NCR-faction apparel.

Veronica
Veronica will accept any apparel specific to the Brotherhood of Steel. Additionally, Veronica will accept apparel specific to the White Glove Society, and giving her the item White Glove Society attire will result in her teaching you the unarmed move Scribe Counter.

Permanent companions
You can have up to two companions, one humanoid and one non-humanoid. All companions' default weapons have unlimited ammo. If you equip your follower with a better weapon, (DPS is checked) add ammunition and check its count from time to time - they seem to hold on to the new weapon when out of ammo or switch to melee instead. All permanent companions have a unique quest line that you can follow in order to "upgrade" them.

While actively following you, permanent companions are treated as essential (unless you are playing on Hardcore Mode, see below). It is important to note that they are only essential when following you, and they can be killed both before they join you and after you tell them to leave. In Hardcore Mode, companions can be killed even while actively following you, but they do not require food or drink and are not affected by radiation or drowning either.

Should you tell your companion to wait for you at The Lucky 38 they will be waiting in your presidential suite ready to be rehired. Note that you have to tell them you want to split up through the talk menu for them to go and wait for you. Just selecting the wait here option in the Lucky 38 will not work. In both Casual and Hardcore mode, companions sent to wait in the Lucky 38 will take consumable items left out and can possibly even take items stored in containers (they will take and consume items from containers. Preferably Nuka-Cola Quartz...). These items are not retrievable from your companions' inventories. Consumable items may also be used by active companions when transferred into their inventory. In fight situations even ED-E will use consumables.

There are 8 permanent companions and recruiting them all will earn you The Whole Gang's Here Trophy/Achievement. Note: This does not mean you must hire all 8 companions within a single play through the game. You may recruit half of them with one character build, and recruit the other half the next time you build a character. It seems to be enough trying to hire a companion for that achievement, even in one game. If you already have one or two followers (1 human + 1 non-human), and try to hire another one of the same category, the potential companion will refuse stating that there's no space. This already counts towards the achievement. Doesn't work on PS3. On 360 This worked simply by meeting and talking to all 8 in one play through.

There is a cheat to obtain the trophy 'The Whole Gangs Here'. simply keep re-hiring any one companion until you get the trophy

(It is possible to collect all 8 if you wish, just send each of them to the lucky 38 one after the other, this is easier if you wait to attack any factions until you have collected them)

Behind the scenes
Several remaining resources point to the game having at one point allowed for the Courier to have multiple humanoid companions. Primarily this is found in disabled dialogue options, such as a conversation with Mortimer where the Courier would have needed to specify which of their human companions they were offering to Mortimer.

Returning Lost Companions
The following fixes work when you lose one or both companions and are unable to find them at either your Lucky 38 suite or in their original home locations


 * Go to Vault 22 and use the central elevator (which you may need to repair at a skill level of 50). Take the elevator to another level. Your missing Companion(s) will be waiting there at the exit of the elevator. You will need to use the Companion wheel to tell them to follow you again as they will be in "Wait Here" mode. It appears that the game does some sort of companion check when using this elevator, and will move your companions here regardless of their status.
 * Push the Tilde key and then type in.

The Ref id's for companions are listed on their respective pages. You can use (instead of both commands stated above) too - if you want to know where you lost your companion. Be sure to make a new save before using any Console Commands. This bug might be related to times when a companion wants to converse with you about his/her quest. In that case, after retrieving him you will need to initiate such a conversation yourself to make the person start following you again. If he/she still stands there and doesn't run after you after the conversation, you can try firing the person from the team and rehiring soon after. This should make them follow you again.


 * Sometimes a companion will disappear and not seem to be retrievable by fast travel or the moveto command.


 * In that case, attempt this:

Move all items from the targeted companion over to yourself to avoid losing them.

See Console Commands for more information on how to use the console.


 * When entering the Legion Fort, upon leaving via fast travel, your companion(s) may not follow you. They will be waiting at the Forts main gate.


 * Sometimes, if you direct Rex to go back to the Lucky 38, he will disappear; in this case, he may be inside The King's School of Impersonation - simply go inside, look around, and you may see him run past you, out the door, and up to the Presidential Suite at the Lucky 38, where he'll be available for dialogue again.

Bugs

 * Everything in ED-E's inventory will be lost when you leave it with the Brotherhood of Steel or Followers of the Apocalypse for upgrades. This is because 'old' ED-E is replaced by 'upgraded' ED-E.


 * Companions attributes drop to a very low level, eg. Veronica, original unarmed 103, drops to 31. You can use console command 'GetAV unarmed' to check the value.


 * Bringing companions that have weapons into Casinos and other places that remove the players weapons will sometimes remove the companions weapon also, putting it in the players inventory. If dropped on the ground -- it will say "Steal" or "Take" with no weapon name shown, and you cannot pick it back up and your companion can only use your weapons with ammo supplied with it. You can workaround this problem using the console. Select the companion and then use "additem  1" to return his or her weapon.
 * Note: Rex and Ed-E are safe, as they don't use actual items for weapons. (EDIT:  Not entirely true; Rex's "Bite" can be placed in your inventory with certain bugs, most notably after completion of "For Auld Lang Syne".) Not true about ED-E either as I exited the casino with him and his Electrical Zap was no longer listed in his companion wheel and in battle he would not initiate combat.


 * Be careful when entering an area populated with enemies such as caves because if you enter and your companions are too far away when you enter, they might be placed in the middle of a group of enemies and possibly die before you can get to them.


 * Sometimes in a fight, a companion's limb(s) may become crippled. If the fighting ends before the player has a chance to heal them, the companion in question will regenerate their health, but not the health of the affected limbs.  This happens especially if the companion was knocked unconscious during the fight and will result in them hobbling around behind the player holding the injured limb.  The issue may be resolved by dealing non fatal damage to them and then using a stimpak on them via the companion wheel. Sometimes same happens and your companions voice keep complaining about limbs when dismissed or replacing with another companion. (Happened with Veronica) There is no verifiable way to resolve this problem.


 * Dismissing companions to the Lucky 38 can sometimes result in them staying in the same location instead of moving to the Lucky 38. So if you cant find your companions at the 38, check where you dismissed them.


 * Make sure your companions are not stuck before you zone into another area as they will sometimes remain still and not follow you into the new area.


 * The option to dismiss companions to the Lucky 38 will disappear even before Mr. House becomes hostile to the player.


 * Sometimes, companions will constantly talk to you if you look in their direction (Boone,Cass and Veronica).


 * Companions may sometimes end up with the weapons of other companions (i.e. Boone having Arcade's plasma defender as his default weapon), causing the other companion to lose their weapon permanently. This may be caused by the weapon removal glitch in casinos or the Fort.


 * Sometimes when wandering near mountains, your follower(mine was Arcade)may get stuck in a part of the mountain. When I had Arcade, he was only shown from the waste up and he was stuck in the rock. You will still be able to speak and dismiss the follower but the follower just stands in place. Reloading from a previous save where this wasn't happening will fix this, but try fast traveling first if possible. "Needs confirmation" On the PC, this can be fixed by targeting the companion in the console and typing moveto player.


 * Sometimes you will lose companions completely and they won't just show up. You will still have their perk and they are considered invited with you, but they are nowhere to be found. Several players have found that they will reappear if you use the elevator in Vault 22, wait for over 72 hours and they will return to their home as if you dismissed them, or just randomly show up while you continue to play. Waiting 72 hrs then going to Vault 22's elevator made Raul re-appear after he mysteriously disappeared. (Nov 25 2010)


 * Others have had issues where their companions will be lost for dozens of hours and have yet to find them, or have them return home. While they are "lost" you are unable to dismiss them, or recruit another companion to take their place. If you cannot find your companion eventually you will be unable to visit Caesar as you are considered "not alone".


 * When dismissing companions in The Fort they will walk to the main gate to cottonwood cove and wait there


 * Upon completing the quest "I Could Make You Care," Veronica may sometimes stop following the player. Though she remains a companion and her companion wheel can be accessed, she remains standing in place once the player finishes speaking to her, and will not move from her position unless her companionship is terminated. (Confirmation needed on many of these particulars) Secondary confirmation about Veronica getting stuck when completing "I Could Make You Care." Firing\re-hiring did not fix the glitch on the PC, This could happen with ED-E after he returns to Prim, when you leave it with the Followers of the Apocalypse(When you say "maybe" to the Brotherhood of Steel). On 360 this is caused by a failed conversation between Veronica and the elder if you reload a save when she will follow you re-enter the elders chamber and watch there conversation she will follow afterward.


 * If the player recruits Boone, Veronica, Raul, Rex, and Ed-E they will get the achievement "The Gangs All Here".


 * Leaving certain areas (notably the Lucky 38 and the Novac Gift Shop) with Boone in your party may cause a bug where the screen goes black while the audio still plays. This can only be solved by loading a save outside the area. (note: if you can get the game to autosave during a blank screen you will be able to load that autosave with no problems.)


 * On my game when trying to equip better weapons for my companions all they do is leave it in their inventory therefore all my companions won't have better weapons i.e. Boone only has his hunting rifle even though he has a Anti-Materiel rifle with several hundred bullets.


 * On my game at times when i switch companions weapon style from ranged to melee their weapon gets stuck inside them and they end up punching the target or shooting from an invisible gun.


 * If you have several companions in the Lucky 38 at one time and leave Weapons laying around they may start to fight each other and they will die due to the fact that they are no longer listed as an essential anymore.No solution as of now


 * Sometimes, if the player climbs a rock that his companion can't climb, the companion will try finding another way to reach the player. This can be fixed by fast traveling to somewhere, but as soon as you fast travel, your companion will star running straight. You can run after him and speak to your companion. This shall fix the bug.


 * Fast travel to Cottonwood Cove and you may lose all of your companions.


 * It's possible that you can lose the ability to hire or dismiss companions that you've already previously hired -- the dialogue option simply doesn't show up. An apparently-related bug is that during certain sequences where your companions are not allowed to follow you (most notably when entering the Lucky 38 for the first time), your companions are ordered to wait but will not resume following you when ordered.
