While walking around the city, you'll sometimes encounter citizens in need. ISAC will scan them for you and identify which consumable you can give them. So far, this only results in you getting an extremely minor amount of experience points - seemingly less than 1% of a level for me. What is the benefit of helping these guys?
The main reason to help civilians in need is for the XP and for the items they drop. At least in the beta, the item was typically a cosmetic item but I've heard they can drop weapon skins as well.
Everything I've read about leveling up quickly has said to help the civilians in need for the XP. So I'd say the main reason to help them is for the XP.
I kept track of how much XP Civilians in Need gave me today, and this is what I found:
- At level 6, 209 XP
- At level 7, 213 XP
- At level 8, 219 XP
(Note that I have already unlocked the +10% XP perk, so these numbers include that bonus.)
This means as you increase in level, so does the amount of XP they give. Of course, at lower levels this will still be a higher percentage of the amount of XP you need to get to the next level, but they definitely aren't worthless (IMO) as you progress through the game.
