Sgt. Daniel Contreras

Sgt.  is a NCR supply merchant in Camp McCarran in 2281.

Background
Sgt. Contreras can be found in the Camp McCarran supply shack. The supply shack is accessible inside the terminal building beyond the large Concourse sign and down a terminal tunnel that veers to the left. Contreras deals in shadier businesses, where it is implied he is making chems on the side for money among other things.

Quests

 * Dealing with Contreras: After attaining a level of fifteen, Contreras will send you on some errands that benefit his business. After doing so, he rewards you with This Machine.

Appearances
appears in Fallout: New Vegas.

Bugs

 * Sometimes after buying stuff from him, the game will freeze with no way of restoring movement. Be sure to save before making deals with him.
 * Once you end the conversation/bartering, the subtitles (if turned on) for his "goodbye" message are displayed but no voice is heard. Also, at that time, his facial expression stays the same (no lipsync at all). A single left-click ends the conversation, and the game continues as normal.
 * This is not a hard freeze on the PS3. Wait about 30 seconds and then start tapping a few buttons (square usually works to get the game to back out of the conversation).
 * The game doesn't actually freeze; the conversation options just don't show up. If you wait a few seconds and hit "A", you exit the conversation normally.
 * Sometimes the option, "Where was I supposed to meet Price again?" is available before Contreras even tells you to meet with him, and remains an option forever after.
 * His unmarked quests can be quite buggy and not work right, such as an incorrect response after killing the Ranger at Miguel's for him with no follow up.
 * If you already have a set of Combat Armor, Reinforced Mark 2 and drop it inside Contreras's shack, any set of mark 2 armor purchased from him will be in perfect condition regardless of the condition that was shown in his inventory before the purchase. But if pick up the armor you dropped, all the armor purchased from him will disappear from your inventory.
