Colossus Timing Attack

Pylon

The protoss supply building; it produces a radius of energy that is a requisite for the placement of most other protoss structures.

Gateway

Warps in the zealot, the stalker, the sentry, the high templar, and the dark templar.

Assimilator

Allows probes to harvest vespene gas from geysers.

Nexus

Produces probes and is the place that all minerals and gas are dropped off at to be processed. Also produces the mothership.

Cybernetics Core

Allows for the warping in of stalkers and sentries. Also allows research of weapon and armor upgrades for air units.

Stalker

A mobile ranged unit that can blink short distances.

Warpgate Research

Allows Gateways to transform into Warp Gates for instant unit production.

Assimilator

Allows probes to harvest vespene gas from geysers.

Robotics Facility

Warps in the warp prism, observer, colossus, and immortal.

Gateway

Warps in the zealot, the stalker, the sentry, the high templar, and the dark templar.

Immortal

A heavy assault strider with a barrier that absorbs damage.

Robotics Bay

Formerly known as the null circuit,[6][7] this structure enables a robotics facility to produce colossi and contains upgrades for observers and warp prisms.

Colossus

The large quad-legged vehicle fires lasers in a splash pattern well-suited to destroying swarms of weaker units. This unit can also traverse differences in terrain height due to its long legs, and will appear to step over ledges and other obstacles due to the inverse kinematics system.
