Gateway

The Gateway is a Protoss building used to "create" infantry. It creates a swirling rift that warps in Protoss warriors from their home territories to the location of the military colony housing the Gateway. A phenomenal amount of energy is required for this operation and, as with all Protoss structures, a Gateway can only function if it is powered by the psionic matrix formed by a network of Pylons.

Gateways are an inferior form of the Warp Gate technology which was lost during the Aeon of Strife. (The Protoss maintained the ability to use Warp Gates, however.)

 * Warp Gate redirects here. For the Xel'Naga-crafted Warp Gate, see Warp Gate (Xel'Naga)''

The Protoss have significantly upgraded the Gateway for the upcoming conflict: it can now be transformed into a new version of the Warp Gate.

The Protoss inventors barely understand the technology, as it has been reverse engineered from ancient Xel'Naga structures found on both Aiur and Shakuras.

Warp-In
A Warp Gate can warp-in Protoss forces to any part of the battlefield that lies within the Psionic Matrix... which can be expanded by the very mobile Phase Prism. This enables Protoss forces to be transported directly to the front lines, to beleaguered outposts, or even to launch ambushes. The forces quickly warp in, gaining hit points over time. If the units fall outside the Psionic Matrix during this process (for instance, if the supporting Pylon or Phase Prism is destroyed) then they are destroyed. Each Warp Gate has a cooldown equal to the production time of the unit it just produced before it can warp-in another unit. All Warp Gates can be selected by using the "W" key. The Warp Gate does not have the ability to summon units regularly, but can be quickly transformed back into a Gateway.
