Sector 3 acts as the main hub for access of most of the facilities and places in Mech Crusaders, and can be accessed via the game's sidebar.
Here is a list of the primary areas for Sector 3:
- Commercial District
- Trade District
- Administration Offices
- Battle District
- Central Hub
- The Wastelands
Sector 3 is mostly ruined urbanized land, but there remains a small forest near one of Sector 3's playgrounds where a creature called a Drazil lives, and this lizard was the basis for the hobby sporting game Drazil Wars.
