The Courier must find and detonate all 30 warheads in the Divide. Any detonated warheads leave behind flames. This can be accomplished after finishing the story of Lonesome Road by revisiting these locations.
- After retrieving the detonator at the marked men camp, go south and detonate the warhead on the army truck to clear the path.
- Turn west and follow the path towards the Hopeville missile silo bunker. Detonate the next missile at the Hopeville women's barracks.
- Turn east again and follow the road through Hopeville until you reach a Hard locked gate. Open it with sufficient Lockpick skill or go through a passageway slightly south. Continue on the main path to find another warhead in an army truck. Nuke it to clear the way.
- Before continuing down the road to the collapsed overpass tunnel entrance, first head immediately East and take the first road to the south towards the wrecked trucks at the marked men supply outpost. There will be another nuke.
- Backtrack your way to the previously detonated nuke and head towards the overpass tunnel. Before you can reach it, another warhead lies in the back of an army truck.
The High Road (4)
- Follow the High Road and just before reaching The Crow's Nest there's a warhead stuck in the highway.
- After the Crow's Nest, the highway will bend to the south, and another warhead is seen in an army truck that is surrounded by deathclaws.
- The end of the highway is marked by a collapsed tunnel overpass. Leave the highway by making a U-turn to the right and head towards the Junction 7 rest stop, where the next warhead is located.
- Now slightly backtrack your way onto the highway, where you'll see a small off-ramp leading east-northeast at the billboard sign. Follow that path, take the first road to the right and a wrecked crane will come in sight. Just behind a nearby rock lies the nuke.
The Courier's Mile (2)
- To find the first of the two nukes here, go past the first large concrete road slab on the right that's bedded into the ground and look to your right, slightly past to what's left of a building in the south-southeast. The orange top of a nuke will be visible.
- Go back to the road to the previously mentioned slab position and walk just past the second upright slab, on the left. Walk just a bit onto the rubble and the second warhead will come in sight.
The Divide - before the Cave of the Abaddon (5)
- After having ED-E launch the missile at the Ashton silo control station to unlock the Courier's Mile, and traveling the Ashton missile silo lift, the Courier will end up at the top of the Sunstone Tower roof. The warhead is found to the left of a billboard.
- A second warhead lies close by, to the right of the same billboard.
- Descend down the makeshift stairs and head the only way possible, southwest. The road narrows and eventually is blocked by rocks and another warhead.
- The road ahead becomes blocked by the explosion, so turn northeast to bypass it through a cave. Before you reach it, on the right is a warhead sticking out of the rocks.
- Turn slightly to the north and just a little further up ahead is the entrance to the Cave of the Abaddon.
The Divide - before Ulysses' Temple (8)
- After arriving on the Boxwood Hotel roof, having lost ED-E, descend the stairs and head south. Go around the flattened building towards a sewage pipe. Go past it and enter a small cave, where a warhead will be in plain sight sticking out the rocks.
- The explosion has caved in the entrance once entered. To leave it, detonate the warhead that's fallen down with the rubble blocking it.
- Outside, go straight northwest, to find a warhead blocking the path to the east of the flattened building.
- Once the warhead is gone, a path below a building becomes a passageway towards Ulysses' Temple. Immediately beyond it, look up to the right to discover a warhead in a marked men camp.
- Look straight upward to see another nuke buried in the rocks above the temple's entrance.
- To the left will be a sewage pipe. Go around it and detonate the nuke that comes in sight, creating a path leading up and over the previous building.
- Go slightly up the building, but make an immediate turn around the rocks at the building's base, going south towards the wastewater treatment plant. , To the left is the next warhead.
- Follow the path past the rock face to the southwest and get rid of the wedged in nuke that's dangling closely above a building. Then backtrack to the flattened building and pass it. Make a slight drop and turn west to pass a lifted fence walkway between two rocks. Go through the top floor of the building and descend to the entrance of Ulysses' Temple.
Ulysses' Temple (6)
Six warheads lying in plain sight among missiles, once the Courier has taken the elevator down to the temple's missile bunker.
Grants 500 XP and the Warhead Hunter achievement/trophy upon completion.
