Mission one,

Personal strategy

1. Create a bunker send 4 marine and an scv to fend of the coming marine wave, a siege tank would be nice
2. build missile turret 5 - 6 near the medic commentator from tycus previous stage, add 4-5 scv to guard them.
3. Build 5-6 goliath and 2-3 medics send them to the turrets
4. Have tycus and 2 medics guard the base near command center, build a turret or two and a bunker.
5. Timing and managing you resource is key here and if plan carefully you would only lost 4-5 colonies.

After my 5th retry finally beat it.

Mission two

There is a way to 'cheat' your way out, here is how.

1. On start command all unit to stop attacking the rock, instead use them to defend the base.
2. Harvest mineral and gas until at least 1000 each.
3. Create 4-5 missile turret to fend of the zerg fliers from left base near the bunker, send 4-5 scv and 2-3 medics to help guard.
4. Build 2 siege tank to help fend of the banelings wave from the right base, send 3-4 scv and a medic to help guard.
5. Build a factory have it fly and land here :

6. Create 3-4 siege tank and 3-4 goliath.

7. Go to the second rock, don't destroy any zerg building.
