SPOILERS FOR DUST BELOW










I've been playing the DUST Survival Simulator mod by naugrim04 recently and fell in love with it almost instantly.  The only thing I don't like about it is that The Courier is hostile when you meet him, and killing him is the only option, so I changed that!  This is the first mod that I've ever made for any game, aside from changing damage values in the G.E.C.K. for various weapons, so don't expect a Willow or Niner companion, but there are various options.  These include:

Fully voiced Courier Companion from DUST Survival Simulator (Voice actor is a friend and has no experience, so go easy.  Lip sync files provided by Hopper31)
Access inventory, change combat style, change follow distance, dismiss companion, tell companion to wait through dialogue options
Companion Caller for when he mysteriously wanders off
Some dialogue options for information on the story of Dust, and some comments about areas of the Mojave
Will use Stimpaks if he has any in his inventory
Special gift and conversation when you enter The Divide with him
Unlockable repair menu
Other things that you can find out!

He can be found in The Tomb (also known as Lake Mead Cave)
NOTE:  This is a completely separate NPC from the original Courier from DUST.  He will still be in the cave even if you killed the original Courier. 
ANOTHER NOTE: He follows the same rules as vanilla companions, i.e. is essential ONLY when following you in regular mode, but can die at any time in Hardcore mode.  Feel free to change these options with the "Essential" check mark in the GECK if you want him to stay alive 5ever.
