A Final Plan for Esteban

A Final Plan for Esteban is an unmarked quest in Fallout: New Vegas.

Quick walkthrough

 * 1) Go and speak to Pvt. Christina Morales at Camp McCarran to start the side quest.
 * 2) Retrieve the corpse of her husband.
 * 3) Carry it to the nearby NCR troopers camped just northwest of where his corpse is found.

Detailed walkthrough
Heading south from Camp McCarran toward the map marker is one approach. Just north of the REPCONN Headquarters, the player will be approached by an NCR Trooper who offers some advice about retrieving the corpse. There are several options at this point.

After recovering the body and returning with the news to Pvt. Morales, Doctor Kemp at Camp McCarran will offer discounts on both medical supplies and services.

Bugs

 * Colonel Hsu doesn't always thank you for bringing the body back, after speaking to Pvt. Morales again.
 * Mines fail to appear around the corpse, while the Tripwire Shotgun and Beartraps are still in place.
 * Sometimes Pvt. Christina Morales disappears from the McCarran Concourse Hall after you have started it. If you go to the body, there are no NCR Troopers around to take it to.
 * Sometimes, if you mess about or leave the body at any point (or enter internal locations which require the game to go to a loading screen), it will disappear leaving no other option but to return to an earlier save point and return to the body's location to complete the quest.
 * Ranger Morales is in pieces before you get even close to the body. There are no mines by it. This means that you cannot complete the quest. He may also be stuck inside the pavement, in which case you cannot shoot him.
 * Esteban can be seen blinking even though he is dead.
 * Sometimes, you won't receive the mission after talking to Pvt. Christina Morales, but you will be able to complete it regardless, just not get any reward for it.
