The Constructor is the builder for the Substrate.
Fragile constructor unit. Multiple Constructors can speed up build time or boost unit production.
The Constructor is a non-combat basic unit that is responsible for using stored patterns in its Fabrication Array to construct buildings. In addition, its Fusion Arc allows the Constructor to aid in producing units more quickly when assigned to specific buildings. When buildings or units are damaged, the Constructor can also use the Fusion Arc to fuse nanites into the affected buildings and repair them.
