StarCraft II Mission Guides

Skygeirr Missions

Skygeirr is a Hybrid reasearch lab where you'll go to take care of some unfinished business involving the Hybrids. You'll unlock Infestors and Ultralisks. This guide should cover all of the Skygeirr Normal Achievements.

Infested Guide

Bonus Objective Reward: +3 Kerrigan levels

New Unit: Infestor

The Infestor is a neat unit that lets you take control of enemy units via parasites and, as an added bonus, it can both attack and regenerate mana.


Understand what Burrow does with Infestors and this mission should be a lot easier. Your first objective is to use Fungal Growth on a group of Marines. Go and use the ability on them, then Burrow and watch them perish. Burrow makes your unit invisible unless there is a sentry around, so be sure to use it heavily. The first part has three things you need to infect with a Virophage, move your Infestors to each part of the map. In addition, use Parasitic Domination when the game informs you to.

In the next phase, you’ll be given a base and a new objective: Destroy the Lab Entrance. Like usual, begin by building additional drones. You’re not going to need a lot of troops on this map, actually, except for when the gas is down, and even then you’re just going to want some basic defenses around your virophages. It isn’t until the end that a sizable force is required, you can just use some Infestors and infest a Battlecruiser and a Thor and turn the tide of battle.


With that said, it’s best to take it easy though. Just relax, build some nice defenses around your Virophages, keep your economy up, build up troops. Enjoy the long time when the gas is down to just strengthen yourself and make the rest of it easier. I personally took 30 minutes doing the mission, although you could do it much faster.

The bonus is kind of tricky; you need to get Creep Tumors near the science facilities. Virophages give you one free, so you can just use those or speed it up with a queen. The tricky part is that you need to clear the one on the western side; the Infested Terrans won’t do it for you.

The achievements are… easy, in a way. Defending the Virophages comes down to two steps: clear the area around them, infect them, and then build defenses on the creep. For killing with the infested units, just infest a few Siege Tanks, Thors, and Battlecruisers, and then let them go crazy when the gas isn’t running. That should be enough for you.

After all Virophages are infested and you’ve cleared your achievements / bonuses, just press F2 and attack / move toward the end.


  • Just Getting Inside: Complete the mission.
  • Master of Puppets: Kill 60 enemies with infested units (the ones you infest with the Infestors). As mentioned above, it’s rather easy if you do it with the Battlecruisers / Thors / Siege Tanks.
  • Spreading the Disease: Infest ALL Garrisons and don’t let the Virophage die.
