Acting as a standard T2 Metal Extractor in most cases, the Fortifier can also repair and assist in the same range as a Construction Turret, but with 2x the Buildpower. This makes it a potent and convenient repair station to keep your army and defenses fighting over a contested point.

Economically-speaking, the Fortifier costs roughly the same in metal, energy and build time as having a basic T2 Extractor and 2 Construction Turrets, but with the same health as the extractor, and without the potential to airlift the turrets to new positions.
