Opposite to neat and clean District 5 or Kokkyo 3, the 
Precinct Sigma is more worn out, more dirty. And has more graffiti! But they still keep the 
best features:
- vibrant, saturated colors
- great attention to detail (i.e. graphics detail)
- quick and easy assembly
- modularity and compatibility with all the buildings from this line (they are not modular with K3 or D5 - but they still look great together on the table).
The new 
Precinct Sigma line includes the well-known 
Post and 
Cubicle buildings (both available since 2018 as "bare" version, also compatible with some of the prepaints), as well as the brand new 
Fort and 
Sentry Towers. 
In addition, this line includes little extras to your tabletop. These are 
Building Holoads, 
Sheds and 
Containers.
