Main Objective  |  Destroy the zerg infestation

The map is home to a handful of colonies, four of which are already infested by the zerg. The goal is to wipe out the zerg infestations, but that's easier said than done when the zerg start infesting the non-infested colonies. Non-infested colonies don't show up on your radar until you discovered them, but we've got their locations in our map to the right (non-infested colonies are marked with white dots [and our arrows]; the gray dots are resource caches you can collect for free).

Periodically, you'll get warnings that the zerg are beginning to infest one of the clean colonies. The zerg infest a colony by setting up a virophage in the center. If you view a colony that they're attempting to infest, you'll see the virophage bubble on the ground with a meter filling up over it. When the meter is ful, the colony is considered infested, but if you can destroy the bubble before the virophage is fully formed you'll save that colony. If you fail to save a colony, the number of infested colonies you have you clean increase, prolonging the mission.

As the mission starts, put your SCVs on mineral and vespene collection duty, put the two small ground unit groups on patrol duty protecting the two entrances to your base, and add a reactor to your starport. You're going to need the starport to churn out myriad vikings—virtually all you'll build are SCVs and vikings—so start by doubling its capacity. We also suggest training a couple of medics to keep your base guards in good shape so that you don't have to spend many resources on defending the base.

While things are getting started, you can use the three vikings you start with to clear out the nearest infested colony. It's directly northeast of you and doesn't have much in the way of defense. Roll onto the scene with your vikings in flight mode and target first the flying brood lords. The brood lords can't attack you while you're in the air, so it's free shooting. When the brood lords are toast, target anything else in the sky before landing your vikings on a clear spot on the ground near the burping virophage. Tell the vikings to hold position and they'll do a good job of fending off any small zerg that attack while also destroying the nearby buildings to clear the infestation. When all of the infestation is clear, you'll get confirmation via radio and the marker on your map will vanish.

The other infested colonies won't be so easy to clear. We suggest avoiding the northernmost colony until you have a large group of vikings, but you can start heading southeast once you've got eight or so viking units. Stay airborne at first and kill off the bat-like mutalisks. The mutalisks are the only air-based zerg units that can attack you while you're in the air, so you'll want to kill them off quickly before wiping out the flapping brood lords. As before, once the air space is cleared, drop the vikings down to ground level and put them on hold to simultaneously fend off small zerg attacks and wipe out the zerg-infested buildings. When all buildings are destroyed, fly the vikings back to base and let your SCVs repair them.

The reason we suggest avoiding the northern base (and as well the easternmost base) is because, in addition to a heavy air force, it's got a number of ground units and turrets that'll shoot your vikings out of the sky. Since your vikings can't hit ground units while in flight mode, you'll need to approach these bases with a seriously strong force so that you can keep six or more vikings on the ground. Micro-manage your grounded vikings so that they take out the ground zerg that are shooting at the flying vikings before your grounded vikings bother with the buildings.

If you're not keeping tabs on the non-infested colonies, however, you'll start getting more to worry about. When you get the warning that a clean colony is becoming infested, we suggest directing your attention to it at the soonest possible convenience. Even if it isn't convenient. Infestations-in-progress aren't too dissimilar from full-on infested colonies, but there will be many fewer buildings to destroy...and time is more of the essence. Clear the air, again attacking first the mutalisks before wiping out the brood lords, and then land on the ground with your vikings to immediately attack the virophage and destroy it. When all infested colonies are destroyed and all infestations-in-progress are halted, the mission ends.

Simply completing this mission earns you +3 protoss research.
