Nexus SC2-HotS Art1

A nexus

The nexus is the heart of a protoss base.


Nexus SC-G Game1

Nova overlooks a nexus

The nexus is a mammoth, pyramidal structure that looms over each and every protoss settlement. It serves as a psychic anchor, allowing the protoss to access the psionic matrix from even across the galaxy. The nexus also manufactures probes.[1]

Khaydarin crystals are located within each nexus. They can be used as a defensive measure when the psionic matrix is supercharged by a mothership core. In turn, each nexus is linked to these cores through its khaydarin crystals, and can serve as a warp beacon to initiate recall.[2] A nexus can also produce a burst of energy that creates a chronal distortion field, briefly accelerating the production of a single structure.[3]

Game StructureEdit


The nexus serves as the hub of any protoss base. Unlike most other protoss buildings it can be warped in without a pylon. It constructs probes and serves as a processing center for minerals and vespene gas.

Nexus SCR Game1

The nexus in StarCraft: Remastered

In the StarCraft beta, the stargate was originally known as the nexus.[4]

StarCraft IIEdit

The nexus remains much the same in terms of cost, appearance and function in StarCraft II. The protoss core macromanagement ability has been moved here.[6]

Chrono Boost gives the player the choice of affecting the nexus, gateway, stargate, robotics facility or boosting upgrades at other structures—almost any building in the protoss base can be an option.

One additional attribute is that it can now warp in the mothership, or in the case of Heart of the Swarm, the mothership core.

Chrono Boost

This ability increases the production speed of a structure by 50% for 20 seconds.

In Legacy of the Void, this ability is set to autocast on a target structure of choice.[7] Efficiency is reduced to 15%[8] but the effect remains indefinately.[7]

It has no effect on allied buildings and cannot be used on incomplete buildings.

Heart of the SwarmEdit

The mothership core is built from the nexus in StarCraft II: Heart of the Swarm. The mothership is no longer produced from the nexus, instead being built from the mothership core.

Photon Overcharge

In Heart of the Swarm, the mothership core uses this ability on a nexus, which gains a photon cannon-like weapon. The weapon has range 13, targets air and ground and deals 20 damage. The weapon lasts 60 seconds and has its own cooldown of 1.25.

In Legacy of the Void, this ability is cast on pylons, dealing 30 damage[7] with a cooldown of .71 seconds.[10]

The following section contains information from a previous version of StarCraft II which is no longer valid.

Nexus SC2 DevRend1

Early nexus render

The nexus went through many small changes. As a primary structure, the scale was adjusted often, specifically the pyramid shape in the middle. The only significant overhaul was done with the intention of increasing the polycount on the curved surfaces around the structure.[13]

The chrono boost ability was briefly removed during the beta of Legacy of the Void.[7]

Ruins of a nexus

A "nexus" is a term that refers to "a central or focal point," or "a connection or series of connections linking two or more things." This fits the nexus given its central role in the protoss tech tree.

The Nexus is the name of the primary setting of Heroes of the Storm. Its shared name with the protoss nexus is brought up by Jim Raynor in the game's tutorial.
