Getting StartedReviewed August 2026

Your first seven days

Build a strong account foundation before chasing raw Influence.

  • Keep construction and investment queues active.
  • Join an active faction before starting long timers so faction helps can reduce them.
  • Push Mansion prerequisites, resource stability, and the Investment Center together.
  • Save flexible speedups for event windows when the same action can earn rewards.
TurfReviewed August 2026

Buildings and upgrade order

The Mansion gates turf progression, while support buildings determine what that progression can sustain.

  • Mansion: raises the ceiling for other buildings and unlocks features.
  • Investment Center: unlocks economic and combat research.
  • Training Centers and Hospitals: balance force growth with wounded capacity.
  • Faction Club, Hostage Cell, and Interrogation Room become major late-level gates.

Investment priorities

Treat investments as a branching plan, not a list to complete at random.

  • Economy investments compound by improving build speed and resource flow.
  • Crew investments unlock higher associate tiers and core combat statistics.
  • Switch into investment-speed gear, skills, and buffs before starting a long project.
  • Wait for faction helps before spending speedups whenever the event schedule permits.
CombatReviewed August 2026

Associates and counters

Bruisers, Hitmen, and Bikers form the core combat triangle; Cars fill a specialized role.

  • Build around one primary associate type before spreading upgrades broadly.
  • Match enforcer crew buffs to the associates actually marching.
  • Scout first and change formation when reliable information is available.
  • Track wounded capacity and healing resources before committing to prolonged fighting.

Enforcer development

Concentrated enforcer development produces useful teams sooner than leveling everyone evenly.

  • Separate Campaign skills from crew buffs used in standard battles.
  • Choose a small core that supports your main associate type.
  • Gear and rank unlock meaningful performance improvements.
  • An Underboss affects every march and wall defense, so choose deliberately.

Formations and scouting

Formation choice is strongest when it responds to the opponent rather than habit.

  • Use scout reports to identify the exposed front line.
  • Pair your formation with the associate counter relationship.
  • Preset defensive and rally formations to reduce mistakes under pressure.
  • Treat incomplete scout data as uncertainty, not certainty.
EventsReviewed August 2026

Event stacking

Efficient players make one upgrade score in several places at once.

  • Check Personal, Hell, faction, and seasonal milestones before spending.
  • Pre-stage resources and timers, then finish during the matching scoring window.
  • Do not sacrifice account priorities for a low-value milestone.
  • Record recurring task values so the faction can coordinate high-value assignments.
FactionReviewed August 2026

Faction fundamentals

An active faction is a progression system as much as a social group.

  • Faction helps shorten construction and investment timers.
  • Raids, reinforcements, gifts, and faction investments reward coordinated activity.
  • Share rally expectations and event assignments before the timer begins.
  • Keep city rules and non-aggression agreements visible to newer players.
EventsReviewed August 2026

Governor's War preparation

Preparation is inventory management: troops, hospitals, healing, speedups, relocators, and clear roles.

  • Confirm hospital capacity before combat.
  • Reserve healing and general speedups for the planned objective.
  • Assign rally leads, fillers, scouts, and reinforcement roles.
  • Follow current city and faction rules; event formats can change.
