A Final Plan for Esteban

 is a quest in Fallout: New Vegas.

Quick walkthrough
Retrieve the corpse of NCR Private Christina Morales her husband, located to the east of REPCONN Headquarters. His corpse is used by Fiends to lure in NCR troops, so take them out first, then grab the corpse and drag it to the troops, they're just down the way to the north of the place you found him.

Detailed walkthrough
Just head south from Camp McCarran toward the map marker. Just north of the REPCONN Headquarters, you will be approached by an NCR Trooper who offers some advice about retrieving the corpse. From the Trooper's position, you should be able to snipe all of the Fiends off of the roof of the buildings surrounding the corpse (about 4 or 5 of them). Afterward, approach from the west (toward the REPCONN Headquarters, the open end of the U-shaped building layout surrounding the corpse). Even though the Troopers warned of traps, there are bear traps by the picnic tables and a rigged shotgun in a walkway between the two buildings.

You will need to carry the corpse back to the two NCR Troopers who you spoke with earlier. When you get close enough, a new note will be added, and you can drop the corpse. Return to Pvt. Morales in Camp McCarran and inform her that the task has been completed.

After speaking with Pvt. Morales, she will thank you and offer to assist you in anything you need, though this is just a figment of thanks. There will be a reward of 50 caps if the player asked for a reward, though you'll lose the karma reward if this option is chosen.

Colonel Hsu will thank the player for their work after the quest is completed.

Journal entries
"Private Morales has asked me to find and retrieve the corpse of her dead husband. His body is apparently being used as a lure to draw in NCR troops and slaughter them.  Better keep a look out for traps and snipers...

The body is just east of Repconn HQ and I should carry it to the troopers camped out on the north side of the railroad tracks."

Warnings
A NPC (Non Playable Character) may accidentally detonate the mines around the corpse (for example a Traveler or a Fiend), blowing Private Morales to pieces and not allowing you to win this quest.

Bugs
The corpse of Private Morales will occasionally blink or get stuck in place.

Be sure that you talk to the NCR Troopers before you reach Ranger Morales' Corpse. If you reach the corpse before talking with the troopers, they won't acknowledge you retrieving the corpse.
