I’ve made a new game and have skipped the Watson lockdown and trying to max level before I do any missions. I’m at level 12 but it’s taking forever.

I’ve searched YouTube and there are a ton of XP guides where they show you good areas to farm XP, but for them to be reliable you have to already be about level 20-30 otherwise it takes forever to down enemies because you can’t access most weapons or you do so little it’s just tedious. I already have 27 street cred and have the arm launcher but it really isn’t enough, it’s better to use a sniper but it takes 3-4 headshots for each person.
