StarCraft II: Wings of Liberty/Protoss buildings

Gateway
Has the ability to be upgraded into a Warp Gate, which can "warp in" units across the map to any spot within the range of Pylons or deployed Phase Prisms. Each Warp Gate can only "warp in" one unit at a time and is subject to a cooldown period before it can use the ability again. In addition, newly warped in units will gradually materialize and be vulnerable for a period (like a newly warped in Protoss structure), and if the Pylon or Phase Prism is destroyed while the unit is being warped in, the unfinished unit will be lost.

Dark Obelisk
It allows Dark Templar to be built.

Null Circuit
This structure enables a Robotics Facility to produce Observers.

Phase Cannon
A defensive building very similar to a Photon Cannon but with the ability to be transform into an energy structure within a Pylon's psionic matrix radius and then move, albeit slowly[54] (compared with a Stalker's blink ability or a Gateway's warp-in). The Phase Cannon replaces the Photon Cannon.
