Stag could spawn at level 4 and/or 5 notoriety. And Level 6 is Zin with all their ass-kicking stuff such as Marauders or Murderbots. Or, instead you could make Stag spawn as normal pedestrians just like gangs, and ride around the town on their n-forcers. Also adding ultor from mission The case of mr. X would be fun, i dont know about the vehicles they could use, but seeing them would be definitely fun. We got gangs from the past, so why not ultor?
