Vehicles production structure
The Warp Sphere can best be described as the Scrin War Factory. It consists of a large 'gateway', similar to the Portal, but running under rather than over the large, blue orb suspended at its centre. This sphere is a teleporter, more powerful than that contained within the Portal and is able to transport Scrin ground vehicles from either across space, or simply down from orbit; precisely where is as yet unknown.
As with the relationship between the War Factory and Tech Center, Warp Spheres may only bring forth the most basic of Scrin vehicles without a Nerve Center and/or Technology Assembler nearby. With a Technology Assembler present on the battlefield Scrin Foremen may even call for towering Annihilator or Reaper Tripods to be teleported in. Owing to their size and complexity, larger Scrin vehicles take longer to materialise, as well as costing more Tiberium. They repair units as well.
