The biggest scores aren't pulled off alone. GangCity has three coordinated heists where you team up with other players, each with its own team size and roles. If a single participant fails their role, the whole job is at risk — cooperation and preparation are crucial. If you're in a family, the proceeds can flow into the shared family vault.
The most accessible joint heist. A player opens a heist as host (for example on a transport) and sets up a lobby that stays visible in the city for a while. A second player joins in with a car from their garage as the stake, and the heist begins. A good car raises the success chance, but you lose it when you take part.
Available from a mid rank. Three players each fill a specialized role:
All roles need to be filled before the heist can be carried out.
The biggest score, for advanced players. Four roles work together: a driver, a demolitions expert, a weapons expert and an organizer. The stake (and therefore the reward) is higher than for the smaller heists, and there are several difficulty levels that affect the success chance. This is where the real tension lies: high risks, big rewards.
For all three: a strong team with good gear and vehicles gets much higher success chances. So build a network of reliable allies to run these jobs with.
