How to successfully execute the Protoss Void Rush for Starcraft 2.

The Void Ray is a very unique unit with a distinct Protoss feel. Few tier 2 units in the game can inflict so much damage in such little time, and so it did not take long for Protoss players to abuse the potential of this unit. Requiring only the Cybernetic Core as a prerequisite and the Stargate to manufacture, the first 200/150 Void Ray can be brought to the field very quickly – especially with some help from Chrono Boost.

Protoss players would quickly block off the entrance to their base, hopefully prohibiting the enemy from knowing what they’re up to, and then send 2-4 Void Rays to attack their unsuspecting enemy right inside their home.

The usual harassment at this point of the game focuses on the mineral line, but Void Ray rushers do not compromise for such petty means and go straight for the Town Hall. Players who lack any sort of anti-air will lose immediately, while others who can defend will spend the next few minutes losing various units and buildings to hit and run attacks while the Protoss player solidifies his economy and expands. Players who wish to use this strategy must make sure they possess the ability to micromanage these attention-requiring units, which are quite slow and not heavily armored, while also taking the time to take care of their economy and production.


Counters:
  • Stalkers with Sentry (Sentries are light and, with Guardian Shield, take little damage from Void Rays)
  • Mid-sized Marine groups
  • Hydralisks
