Hier alle locaties, ge-copy-paste van gearbox forums, SPOILER alert dus:
1. Sledge’s Safe House
This claptrap is found at the end of a dead-end hallway, just after the room with a broken ceiling and part of it forming a ramp on the left.
2. The Lost Cave
Found deep in the back at a bandit camp nestled there. Can be easy to miss if all you did was restart the game to respawn the broken crystals close to the entrance instead of playing through the zone normally.
3. New Haven (x2)
The first claptrap is next to the bulletin board.
The same claptrap gives an expansion in the Second Playthrough instead of an item like all of the rest.
4. Tetanus Warren
This one should be in the area where the cave splits. On the left should be a bunch of shacks and barricades, as a landmark.
5. Crazy Earl’s Scrapyard
He's in the northern area, close to the wall along the northern section of that area.
6. Krom’s Canyon
On entering the canyon, go to the right hand branch. This is easy to find if you take Earl's sidequest for food. He's way up high on the left, close to the end of the canyon and across the wooden bridges there. His kit is also found on those same bridges, but you can't pick it up until the quest is activated.
7. Old Haven
He's found in the southwest corner of the map in a garage. Look for a building with a sign over the door.
8. Trash Coast
On entering the area, head immediately south. He's somewhere in the middle of that part of the zone.
9. The Salt Flats
This one is found in the camp below Thor, the giant digger.
10. Crimson Fastness
You'll run across this one on your way through the bunker. His kit is also nearby in the next garage.
