Fallout 76 Enclave sees the return of an elusive faction from previous games in the series.
Finding it early in the game means travelling quite far across the map to find the Abandoned Waste Dump location, of which the Bunker Buster quest to join it is inside.
This is also the starting point for how to launch nukes in Fallout 76 - the game's rather involved end-game activity.
Where to find the Abandoned Waste Dump location in Fallout 76
First, you need to go to a specific location on the map - the seemingly ordinary Abandoned Waste Dump. You can find it here:
It's at the far east end of the map in one of the game's higher level zones, so be wary you might find resistance along the way. We highly recommend running into settlements along the route however, so if you do die, you can fast travel to them (at the expense of a few caps) to save you the trip later.
The location itself has a wire fence surrounding a rocky outcrop. It'll be a location when you get close enough to it.
Head to the north-side of this wire fence, where there will be a gap.
Head through and facing east into the rock is an entrance - which where you can enter the Abandoned Waste Dump location to start the Bunker Buster mission.
Need more help? If you are following the main storyline, then you'll come across the Type-T Fuse location and Fire Breathers exam answers quests. If you're after online activities, there is Fallout 76 Workshops and base building and how to unlock PvP. If you're after higher-level goals, then we recommend observing the level zones map, unlocking Atom Challenges, plus how to join the Enclave and launching nukes with launch codes.
How to start Bunker Buster in Fallout 76
Once inside the cave - there will be a loading screen - you need to find a corpse to start the Bunker Buster mission.
The first thing you'll see is a pile of barrels. Walk past them...
...until the cave opens up, and there are several routes to take.
The location you are looking for is on the left side. Turn left, and go in that direction. You don't need to hug the wall (though if you do, you can awkwardly climb some rocks) but eventually you'll come to a Deathclaw nest, which is in a darker corner of the cave and is glowing green.
Investigate the nest and pick up the Bypass Holotape.
You're not done yet. At the other side of the nest is a small gap in the rocks.
Squeeze through, and you'll find a corpse of an 'Agent'. This has the 'Operation Summary - Blackwell' Holotape on them.
Pick it up, and the Bunker Buster mission will begin.
Now complete the objectives set out for you, including bypassing the laser grid, and then finding the Blackwell access code. You can find a full Bunker Buster walkthrough here:
After you listen to the Holotape, Bunker Buster is complete and the One of Us mission will unlock, which requires you to explore the Whitespring Bunker. Highlight the mission and it'll be added to your map.
With the 'Bunker Buster' mission complete, you have joined the Enclave, and can now access the Whitespring Bunker.
