Malton is big--it has, in fact, 100 different suburbs. That's a lot of different areas to visit, and it makes the city seem enormously intimidating to new players. But don't worry--these hundred suburbs can be reduced into 20 districts, smaller groups of 5 suburbs each.
Malton is divided into 4 divisions. Each division is a corner of the map: NW, NE, SW, or SE. Each division has 25 suburbs and is divided into 5 districts. They are written as: SW-2, or SE-4. See the map below.
Historically, each district had it own radio frequency. However, as 20 frequencies became too numerous for a diminishing population, this was reduced to five frequencies that don't follow district lines.
After exploring your home suburb and establishing a base in it, try moving into another suburb within the district. Search around and see what buildings you can find. Try to establish a second base in this new suburb.
If you continue to do this, you can establish a very helpful in-game strategy called "basing". You should have five different bases within your district, as well as backup safehouses. You should be familiar with the locations of all the tactical resource points (TRPs) within your district.
Once you've based up in your district, it won't be long before you create a network of friends in the other suburbs in your district. Try forming an organization. Use your five bases as the five bases of the district, name the district (if it has not already been named).
This strategy allows for easy networking and mass organization, and has been used in many districts around Malton. You can improve your district by using the "basing" strategy and creating a district network for it.
