Members of the gang usually attack the Courier on sight. They are also fairly cowardly; fellow members will often flee if they witness large numbers of their comrades being killed. They continue to hide inside the building until the Courier kills them.
At some point in development, Yvette, the gang leader, would have been the source of an optional, unmarked quest to aid the gang in obtaining "a steady supply of ammunition from the NCR quartermaster at Camp McCarran." This quest was never fully implemented, but some resources related to it remain, in particular a note titled Ammunition for the Scorpions.
