Component Tower
Description:
Revenant forces have a rather unique base defence system. Instead of building turrets directly, they build heavy-reinforced empty towers called ‘Component Towers’. These towers can later be upgraded with either an anti-infantry Hellfire Turret, and anti-armor Guardian Turret, or an anti-air Dagger Turret. The empty towers themselves construct rather fast compared to other defences, making it an effective tactic to deploy some empty towers around the perimeter, and upgrade them later when they are needed.
Do note that when unupgraded, they have no defence, and can only act as target practice or as roadblock (a rather expensive one then).
Renders:

Note: model and texture may change at any point during development.
Non-official comment: after many versions, I decided to base them on the original TS Component Tower, mixed with some own ideas. The end result is what you can see here.
