Every city in GangCity has influential figures who can put someone like you to good use. Through the story missions (city contacts) you build trust with these contacts, unlock heavier assignments, and work your way toward a meeting with the mysterious final boss. It's the storyline that ties GangCity's world together.
Each contact has their own city and character:
Every completed mission raises your trust with that contact, on a scale from 0 to 100. You climb through successive levels as you go, from Unknown through Known, Trusted and Ally to Right Hand. Note: some contacts are rivals of each other — gaining trust with one can hurt your standing with the other. So choose carefully who you align yourself with.
A mission from a contact only counts if you're standing in that contact's city. Want to make progress with Mei Ling? Then you need to be in New York. Traveling is therefore inseparable from the storyline.
Reach a high trust level with multiple contacts, and you unlock the final boss Il Capo. Whoever completes his assignments earns a unique honor and an exclusive weapon — a fitting crowning of the storyline.
