Assimilator
The Assimilator, a Protoss structure that can only be built on top of Vespene Geysers, allows the player to collect Vespene Gas. Probes sent to an Assimilator will return Vespene Gas to the nearest Nexus. The Assimilator is equivalent to the Terran Refinery and the Zerg Extractor, but has significantly higher endurance.
The Assimilator is one of only three Protoss structures that does not require a Psionic Matrix in order to be warped in or operated. (The other two are the Nexus and the Pylon.)
Competitive Usage
The most efficient way to harvest Vespene from an Assimilator is to assign exactly three Probes to it. A worker count text is displayed over the Assimilator. It turns red when the worker count is higher than three.
The timing of when to build Assimilators and transfer Probes from mineral gathering to Vespene is an important strategic consideration. Many Build Orders will specify when to build the first or second Assimilator, and the player must also carefully balance mineral and gas needs during mid-game transitions.
Like its Terran and Zerg counterparts, players will sometimes build Assimilators on the Vespene Geysers in their opponents’ base, usually in the early stages of a match. This maneuver, called a “Gas Steal,” provides several competitive benefits including a delay in the opponent’s ability to gather Vespene. The Probe’s ability to begin warping in an Assimilator and then immediately continue scouting makes the gas steal somewhat easier for Protoss players.
PROTOSS – THE WARRIORS OF AIUR
HONOR. WISDOM. TRADITION.
In stark contrast to the adaptable Terrans and the ferocious Zerg, stand the rigid, tradition-minded Protoss. With their psionic abilities and advanced technology, the Protoss have long considered themselves the most powerful species in the galaxy. This people’s greatest asset is the tenets of their primary religion – the Khala – whose tight framework demands dogmatic adherence.
Protoss Buildings
Another outstanding technical achievement of the Protoss is to teleport their buildings over long distances from their home planet Aiur to the most remote parts of the galaxy. This is done by converting the buildings into energy and dematerializing them within the psifields built on the outposts.
