Your Assets
Influence
Influence is what you will slowly accumulate from over time. Every 3 minutes, your influence will grow according to how much control you have over the station. The more territories your gang has tagged, the more influence you get.
Just remember that Influence is shared between the whole gang, so if you want to promote some lieutenants make sure they're trustworthy and competent, as they're going to be buying from the same funds as you do.
Equipment
Spend influence from gangtools to purchase items for your gang. See the equipment section below for details on purchasable equipment.
Lieutenants
Lieutenants can do everything the boss can but they cannot promote other lieutenants. Lieutenants can recruit, use gangtools, and are immune to deconversion. You are limited to three lieutenants max, and it is recommended that you promote as many people as necessary to reduce the risk of having all leaders arrested/killed.
Picking good lieutenants is important. Don't just promote the first few people you see. Promote those who appear competent and know what they are doing. Promote gangsters to lieutenants with a gangtool.
Gang Management
As a part of the gang's inner circle it is your responsibility to keep you gang going. Spray cans are cheap, and distributing them to your gangsters will allow your influence to grow faster. Even when you have a Dominator active, having more territories will make the timer count down faster.
Communication is extremely important. Your gangtool has the ability to send a message to everyone in your gang at no cost. Use these to coordinate your gang and rally them whenever appropriate. If you have a lot of surplus influence, gather your gang in a meeting area and distribute weapons, armor, and spray cans to them to keep your gang strong.
Avoid travelling alone. Your best avenue for protection are your own gang members. If you are always surrounded by your allies nobody can take you by surprise. It may be a good idea to make sure you always have at least one bodyguard by your side. If your gang is well armed and you are communicating well with them, you could virtually be untouchable.
Following Through
In the early round, resist going around spraying territories with your spray can. Spraying tags leave fingerprints and raises security's suspicion against you. You are far better off passing your spray cans to recruited gangsters, and you can focus on recruitment, equipment, and not getting caught.
Your anonymity is your most valuable asset early in the game. If your rivals spot you converting crew or using a gangtool, they're sure to alert their friends. If they manage to do that, consider yourself marked for death.
Do not allow the station to evacuate. If the shuttle is allowed to dock with the station, you only have a few minutes before you lose. If you use your gangtool to recall the shuttle, keep in mind that station security (or even your rivals!) may use your recall signal to pinpoint your location. Never stay in the same spot you recalled the shuttle from unless you are willing to fight them. Active dominators will also prevent the emergency shuttle from leaving the station. If you've missed the window to recall the shuttle, spawning a dominator may be your only recourse from defeat
Remember that rival gangsters can be reverted to a neutral crew member by beating them in the head! Recruit them yourself afterwards to steal members from the enemy.
