Reactor

The terran nuclear reactor is an add-on in StarCraft II. Its modular design enables it to be attached to barracks, factories and starports.

A structure attached to a nuclear reactor can produce units more quickly. For instance, a barracks attached to a nuclear reactor can produce s twice as quickly. The player must be able to afford both units, however.

The reactor grants an extra-long queue as well.

Note that in multiplayer, a terran structure cannot be attached to both a tech lab and a nuclear reactor, so it cannot enjoy the benefits of both.
