Haven's Fall

When arriving on the planet, Dr. Hanson will plead that you protect the colony. However, the Protoss will demand that it is purged of its Zerg infestation. Haven's Fall is the resulting mission of agreeing to assist the Protoss.

For this mission you'll have access to a new air unit, the Viking. They can only attack air units, however they can transform into a strictly ground to ground unit. The Zerg are abundant and growing in strength. You'll want to pump out Vikings, medics, marines and any other strong units you've acquired. Quickly lash out against the close by Zerg bases. This will dwindle their forces and may provide extra resources to gather.

You need to press an offensive, but be sure to at least leave a basic defense. A siege tank or bunker should service for keeping the Zerg off your heels. With enough of the Zerg bases taken down, they will be unable to produce a sizeable army. Be swift and you'll be able to clear out the colony in no time.

After the battle, the Protoss will award you with a gift for your cantina. Additionally, Hill will have a new Viking mercenary for hire.
