Where do Abadon Crusher Mutants spawn on the surface of the world?
There is a guide for this achievement.
The answer is yes, there are a few random spawn locations where Abadon Crusher Mutants may spawn.
The first location is in southeast of the town 'Gunbarrel' in a meteorite craters. The second random spawn location is in the southwest of the town 'Wellspring'. I found (later) a third random spawn location. Directly above from the first MBTV location in Broken Tract.
