Warhead Hunter

Warhead Hunter is an achievement/trophy for the Fallout: New Vegas add-on Lonesome Road. To obtain this achievement/trophy, you must find and detonate all 30 warheads in the Divide.

Locations
Most warheads are detonated within the course of the story, but there are at least five to ten that are in various corners of the map. Some hunting is required. The only way to detonate them is with a Laser detonator.

1-6: Can be found at the end of the DLC, inside Ulysses' Temple.

7-10: Near Ulysses' Temple, one is buried in the face of the cliff directly above the entrance to the temple. The second is on the cliff face just above the building with the empty pool on its roof. The third will be blocking the path up to the temple, near that same building. The fourth can be found near the entrance of the Wastewater Treatment Plant.

11-12: Are located in The Courier's Mile. One is located to the lower left of the rubble wall in the camp of the Irradiated Marked Men. The second is located on the upper right wall of rubble very close to three Irradiated Deathclaws though it can be easily seen and detonated.

13-14: The first will be blocking the route between the Sunstone Tower Roof and the Cave of the Abaddon. Traveling toward the Cave of the Abaddon, still out in the open, it'll be on your right among a pile of debris. One of Ulysses' painted markers will be on the ground in front of it. One of ED-E's circuit boards will be accessible after the warhead is detonated.

15: At Junction 7 Rest Stop

16: Exiting the Hopeville Missile Silo Bunker, look down the hill. It's Lying on the ground by a building. The building is right next to a billboard with a flag on it.

17-18: (Near Boxwood hotel roof) Inside Rawr's Cave, on the other side of a drainage pond near the overturned section of highway. One will be immediately above you on the cave's ceiling, and the other will block your exit after you trigger the fight with Rawr.

19: In the Marked Men Camp, just south of where you pick up the Laser Detonator. This one is vital to the story line. You cannot proceed without it.

20: Southeast of Ashton Silo Control Station one is located left of an army truck and dead end, it is up against a rock wall.

21: Marked Men Supply Outpost On the east wall beside an overturned truck.

22-23: In the back of a truck blocking the "S" road between the Hopeville Missile Base - East Entrance and Collapsed Overpass Tunnel Entrance. Second one is a little further down, blocking the same road.

24-25: On the bridge between High Road Entrance and Ruined Highway Interchange

Before Collapsed Overpass Tunnel Entrance - 5

 * 1) (Required) After retrieving the Laser Detonator in the Marked Men Camp, you have to blow up a warhead on a truck bed to leave the area. Can't miss it.
 * 2) Head back to the Hopeville Missile Silo Bunker exit. In front of the barracks that is across from the destitute gas station is another warhead.
 * 3) Following the path to the Collapsed Overpass Tunnel Entrance, it branches before entering the ruined city area. Among the bunkers off the right side of the right path is the warhead.
 * 4) In the very southeastern-most corner of the Marked Men-run ruined city you'll find another warhead in the center of the broken-down trucks and vehicles.
 * 5) Just before the Collapsed Overpass Tunnel Entrance is a warhead. Right in plain view.

Before Ashton Silo Control Station - 4

 * 1) After getting attacked by the first group of Marked Men past the Collapsed Overpass Tunnel and moving along, you'll start being fired upon by some more in the distance. Below their building and the path to The Crow's Nest is a warhead.
 * 2) The next warhead is found in the middle of the Ruined Highway Interchange area, surrounded by deathclaws.
 * 3) As you near the end of the highway, you'll come across a fork. Take the right path that heads downward toward a collapsed tunnel and a ruined vehicle. A warhead is near the "Smitty's Diner" sign, near the Junction 7 Rest Stop.
 * 4) After the last warhead, now take the left fork. When you come upon the Marked Men camp, head to the southeast. Tucked in with the rocks behind a truck is a warhead.

Courier's Mile (unlocked after setting off nuke at Ashton Silo Control Station) - 2

 * 1) As you enter the area, you'll see a fork. As you take the right one, you'll be able to see a warhead up ahead in the distance among the destroyed buildings behind the deathclaws.
 * 2) Back and along the left road, you'll come to a path and a clearing on your left full of Marked Men. Tucked away in the back with the ruined buildings is a warhead.

Before the Cave of the Abaddon - 5

 * 1) As you exit the Ashton Silo on the Sunstone Tower rooftop, head to and peak down over the western edge. Below, on the left-hand side of a large white "On Solid Ground!" billboard near a large, collapsed building you'll see a warhead.
 * 2) On the opposite side of the same billboard from the last warhead is another.
 * 3) (Required) From Sunstone Tower, head southwest. Tucked between the boulders is a warhead you have to detonate to continue along.
 * 4) Head around to the right from the last warhead. Up among the rubble on your right, you'll see only the tip of a buried warhead sticking out.
 * 5) (Required) Head northwest from the last warhead. You'll see another warhead wedged in-between the rocks.

Before Ulysses' Temple - 8

 * 1) After reaching the Boxwood Hotel Roof, head southeast. Behind a pipe gushing water you'll find the den of Rawr the Deathclaw. One is embedded in the ceiling.
 * 2) After defeating Rawr, another is used to leave the den
 * 3) (Required) Further along from the last two, at the base of a ruined building where some Marked Men are shooting from you'll spot a warhead.
 * 4) After passing under the building using the path created from the last warhead, look up and to the right. In the distance (above the entrance to the Waste Disposal Station area) you'll see a warhead sitting next to a Marked Man sniping at you.
 * 5) Head south from the toppled building. Around another gushing pipe, up among rocks, you'll find one.
 * 6) After detonating the previous warhead, a path leading up will be created. After climbing up, you'll be atop the toppled over building. Going around to the right will take you up to the entrance of the Wastewater Treatment Plant. The warhead is on the rocks to the left of this entrance.
 * 7) Look out southwest from this area and you'll see one atop the nearby building in the farthest corner.
 * 8) High up and to the right of the entrance to Ulysses' Temple.

Inside Ulysses' Temple - 6

 * 1) Next to you as you walk in, to the right.
 * 2) To the left as you walk in, along the wall next to large missile.
 * 3) Further to the right between two large missiles.
 * 4) Hidden in recess behind first large missle along right wall.
 * 5) Further to the left between large missiles.
 * 6) To the right of center walkway.

Bugs

 * If you have Euclid's C-Finder, there may be some interaction between it and the Laser Detonator to the point where the Laser Detonator will not blow up the warhead. If this occurs, drop the C-Finder, blow up the warhead and pick up the C-Finder again.
