Warp Gates serve as reinforcement portals which can Warp In infantry directly into a Psionic Matrix. The way it functions is quite simple: the Warp Gate first Warps In units, who are 'stored' within the structure. When needed, the Warp Gate can then materialize the units within Pylon Power, who will gradually, slowly building up till they materialize fully. During this time however, a unit is extremely vulnerable and can be destroyed before it finishes Warping In, and the process requires the Warp Gate to rest between teleporting units for 35 seconds. Used in conjunction with Phase Prisms (which can deploy a Psionic Matrix anywhere), the Warp Gate enables great surprise attacks and can send in reinforcements directly into enemy lines. Like most Protoss structures, the Warp Gate needs to be in a Psionic Matrix to function.
