Sgt. Daniel Contreras

 is a supply merchant in Camp McCarran.

Background
can be found in the NCR Supply Shack, the Supply Shack is accessible from a far end of Concourse area via a terminal tunnel. deals in shadier businesses, where it is implied he is making chems on the side for money among other things. Contreras will give you unmarked quests that are fairly easy to complete. Depending on your choices in the unmarked quest concerning inconsistencies in the the base's weapon ledgers, he may give you the unique rifle This Machine. After you have obtained This Machine by reporting him to (Lt.) Carrie Boyd, Contreras will no longer be present to sell supplies.

Appearances
appears in Fallout: New Vegas.

Bugs

 * If you talk to Contreras during the NCR quest I Put a Spell on You, Contreras will not have the option that activate the unmarked quest to retrieve This Machine. (confirmed)


 * Unmarked quest stops at the NCR ranger with no secret stash access or This Machine, doesn't matter if you kill the ranger or work out a deal. (Confirmed by others, tested with old save and bug happening 4 out of 6 times. Don't know cause.)

Confirmed bug. stops at blake quest,dialogue not there from blake.

If you want This Machine and are experiencing this bug you can still report Contreras to Carrie Boyd after the NCR ranger agrees to the deal. To do this just hacking his console on the 2nd floor of the supply shack and downloading the records. Then see Carrie Boyd, you will be given the This Machine as a reward and Contreras will disappear. (Not a huge issue as he is so out of the way once you complete the Camp Quests.)

When asked to deliver the note to Issac, Issac will not spawn outside of Gun Runners. If this happens, going in and out of his house will fix it.


 * When buying supplies from Contreras he will sell a version of the Recon Armor worth 610 caps and in a very poor condition. After buying the Recon Armor, it will be in perfect condition in your inventory. To obtain more perfect copies of the Recon Armor, exit the buying screen and re-enter it to buy a maximum of 3 copies, after which, upon buying more Recon Armor, the armor will unbug and you will be left with only 1 version of the Recon Armor in its normal state.
