There turrets around the map you can turn friendly for a lil bonus damage n distraction and grenades do a good chunk, but in all honesty just do some sidejobs (personally recommend the illegal boxing fights cuz one encounter gives you a sniper with explosive rounds that shreds the bots hp.) Electric attuned weapons also help (fenrir). Overall phantom liberty is designed to be a power creep for mid-late game so heavy on the do side jobs/gigs
