Kill The Machines¶

Follow the tracks and eventually you’ll reach an abandoned ruin which is swarmed with multiple Machines that you’ll need to take down before you go in and search for Boomer. Here you’ll need to deal with three Scrappers and two Clawstriders. Scrappers are weak to Shock Damage and are most vulnerable from the back (Plasma Cell). Clawstriders are also weak to Shock Damage and are most vulnerable from the back (Razor Tail).

Examine the Camp¶

After you’ve cleared out all the machines, head to the back of the area and examine the camp, then activate your Focus again and tag some more Tracks that you’ll want to follow. Eventually you’ll reach a dead end, so use your focus to highlight any climbable surfaces and make your way up to the top. Enter the nearby wreck and examine the device.

Go to the Wreck¶

Head southeast from where you found the device to find another wreckage, then examine the Tools. Here you’ll be ambushed by two Longlegs and one Frost Bellowbacks that you’ll need to take down. Longlegs are weak to Shock Damage and most vulnerable from the Front (Concussion Sac). Frost Bellowback are weak to Fire Damage and are most vulnerable from the large sac on the back. Upon clearing out all the machines once more, speak with Delah and Boomer.

Follow Boomer¶

After the conversation has come to a close, you’ll be given the Boomer Shredder Gauntlet, then follow Boomer until you reach the resting place for a Shellsnapper.
