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 weapon being used.
 * Open inventory - This displays the companion's current inventory, inventory weight, and weight limit.
 * Toggle stay close/keep distance.
 * Back up.
 * Toggle aggressive/passive AI.
 * Use stimpak - also shows current health.
 * Toggle wait here/follow me.
 * Return to normal dialogue.

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 add ammunition and check its count from time to time - they seem to hold on to the new weapon when out of ammo and switch to melee instead.

Whilst actively following you, permanent companions are treated as essential (unless you are playing on Hardcore Mode). It is important to note that they are only essential whilst following you, and they can be killed both before they join you and after you tell them to leave.

Returning Lost Companions (PC)
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.

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

Returning Lost Companions (Console)
If you are unable to find your companion despite waiting or fast traveling, go to Vault 22 and take the elevator to the bottom floor. He/she should be directly in front of you when you step out. It even works when the companion has been told to "Wait here." This can only be done if you have a repair skill of 50 or greater.

Proven: works on Ps3 console.

Bugs
Things your companions kill do not seem to effect your reputation (in all cases).

Disproved with the NCR in 'New Vegas' (PS3)


 * Due to unknown reasons the robot victor will not move from the front of the Lucky 38 from the beginning of working with Mr. House where he will say that Mr. House is waiting up top and that no companions may join you. With Victor still there you cannot send your companions to the Lucky 38 when you part ways, but if they get lost they will return to the Lucky 38. Unfortunately if you go to party up with them again they will not be at the Lucky 38 and will not be where you originally found them, therefore making it impossible to party up with them again.
