Scavenger

Scavengers are groups that are usally made up of Turians and Humans. They are only actually encountered alive once in Mass effect on the planet Trebin in the Hades Gamma Cluster. The scavengers and their civilian M-29 Grizzly are located on Trebin standing around the debris in the north-west of the map. They have low shields and are armed with pistols and assault rifles and their is no cover except the M-29 Grizzly so they shouldn't be to much of a fight even on insanity.
