You start your journey by either joining an existing gang by an invite or asking admins to create a new one (/creategang). Every gang has a color, a tag and a name. 

As a gang member your main concern should be capturing territories and increasing loyalty in the territories your gang already owns. There are activities you can do to capture new territories, you can sell drugs to NPCs, spray your gang tag or just be present in the territory for some time. Not to mention you can easily add your own actions! 

But don't think you can start being lazy once you capture a new territory! If your gang owns some part of a territory your loyalty there will decay over time. Being the strongest gang in a territory has its responsibilities. Someone removes your tag or perhaps sprays their own tag in your territory? Your loyalty will decrease! Same goes if someone kills a resident or robs a business in your territory! Don't get scared, it has its advantages as well!

One such advantange being the ability to collect protection money from businesses! But be careful, all territories you own will be colored in your gang color on the map! That can attract unwanted attention of other gangs and someone might start a rivalry in one of your territories. Rivalry is an addition to Turf War between two gangs, you can start one in a territory that's not yours. A minimum amount of funds will have to be deposited. Once a rivalry starts, for the next 2 days you'll have to start selling as many drugs as you can for only half the price. But at the end, the gang which has sold the most drugs will take all the drug money that's been collected in that time period. 

As a gang leader you can place storage and garage checkpoints. The storage serves as a shared inventory for you and your gang members. The garage let's you add vehicles with custom colors which all your members can take for a spin!
