Primary Objectives[edit]

  • Select Drone
  • Mutate into Hatchery
  • Harvest 300 minerals
  • Morph Overlord
  • Mutate Spawning Pool
  • Morph 6 Zerglings
  • Destroy Gas Turrets
  • Destroy the Eradicator

Guide[edit]

You spawn with only 1 Drone which you are told to morph into a Hatchery. Once it is done, 6 more Drones will be released into your pen. At the same time, you will get a new objective to harvest 300 minerals, worth noting is that you don't need to have all 300 at the same time, spending them is fine. Valerian will tell you to morph an Overlord. Do this by selecting your Hatchery, press S then V. After the Overlord spawns you can choose to morph more Drones, it is not needed to finish the mission but will give you a higher income. Next objective is to mutate a Spawning Pool, same as with the Hatchery but choose the Spawning Pool. After that is done, Valerian says the experiments are done but Kerrigan disagrees. Morph 6 Zerglings and you will get a small cut scene.

After the interlude is done continue to morph Zerglings and send them up towards the Eradicator. Regardless of your chosen difficulty the battles along the way should not prove to be difficult. The mission ends right after you kill the Eradicator.

Sidequests[edit]

  • Release Zerglings from the 3 pens
Destroy the power generators to free the Zerglings
The locations of the pens are marked on your map with yellow markers.

Guide for mad dash
You need to kill off the 3 Factories in the level, the first one is in your way towards the Eradicator, the other two are at him. Make sure your Zerglings don't finish the boss off before you have killed the Factories. If you're pressed for time, you can try to skip the last two Zergling pens and go directly for the Factories in the room with the Eradicator. If you continue to make Zerglings from your Hatchery, you should have more than enough to go for it. Also, you'll probably have more Zerglings than can surround and attack a Factory, so split them up and have them attack both Factories simultaenously.

Easter Eggs[edit]

Drones

If you cross the bridge leading to the first Factory with only Drones Valerian will question you. The turrets beforehand can be destroyed with Zerglings. As soon as the line is triggered you can pull back and continue attacking with Zerglings.
