StarCraft II Mission Guides


Welcome to the start of the Heart of the Swarm Campaign. After these first three missions, you'll have a choice in which missions you'll undertake from there. Our guides will walk you through the missions on Normal difficulty and provide advice on completing the various achievements. So let's get started!


This is the start of your journey, it teaches you basic base building and combat. There is no risk of failure in this mission.


Your first step is to select the drone, then build a hatchery. Then you’ll need to set the drones to harvest some minerals. It’s really easy so far and shouldn’t be all that difficult. Then build an Overlord, in order to increase your supply. No risk, nothing, take your time. At this time you can also build more drones, if you want, to increase your income, but do note you’ll need to make a spawning pool right after, which takes 200 minerals, but the extra drones helps in a little bit when you’ll need to spawn zerglings and overlords and there is a combat sequence up ahead, so you’ll definitely want to have an upper hand during it, if nothing else for ease of finishing the mission.

After the zerglings are made, you’ll be asked to destroy the Eradicator and have a bonus of releasing zerglings from pens. The zerglings from pens makes creating zerglings a joke, realistically, you shouldn’t need to make anymore, but it’s good to get in the habit of constantly refreshing your army.

As you move forward, you’ll run into a room with gas turrets, just attack move and you should be fine. The eradicator was a joke for me, honestly.

Lab Rat Achievements

  • Mighty Mouse: Destroy 35 Sentry Bots, you should completle this achievement with ease.
  • Rat Race: Complete the “Lab Rat” mission in less than 10 minutes, just work as fast as you can and skip unlocking the extra zerglings, keep making more at your base to save time.
  • Lab Rat: Complete “Lab Rat”
  • Mad Dash: Destroy 3 factiories within 10 minutes on Hard. Just keep making zerglings, non-stop, and have a strong economy ASAP to keep producing them.


I really enjoyed this mission, a lot different that the other ones. If anyone is still having trouble with this mission or completing the other missions check out There are some really good video guides there.
