Mission 4: Assault on Korhal

Conditions for winning

• Destroy enemy Physics Labs OR
• Destroy enemy Nuclear Silos

Conditions for losing

• All your structures are destroyed.

After you start off in the middle of the map, you'll have to get up your defenses quickly, as the enemy will come with regular attacks. Place Bunkers on your nothern, eastern and southern flanks with Siege Tanks and SCV support. When you know you can hold them off, build an attack force of 12 to 24 Marines, move them west and claim the resources there.

When you've got your new base set up and defended, build up a large force of around 6 Tanks and 24 Marines, and send them east towards an opponent base, and destroy it with a Sieging method, using your Marines as protectors on Hold position around the Siege Tanks.

Set up another base, and this time, defend all your bases well against only northern and southern attacks. Now, build up a large force consisting of Siege Tanks, Battlecruisers, and lots of Marines and Medics.

You can either slowly push them north for the Physics Labs or south for the Nukes. Which you destroy will affect your next mission. Siege and unsiege your Tanks and attack buildings that come into view, with your Marines in front taking care of any units that come along and your Battlecruisers overhead guarding the rear and finishing off the units that come too close. A SCV or two nearby is probably also a good idea. Personally, I'd recommend destroying the Nuclear Silos, as Nukes are much more annoying than the occasional 3-Battlecruiser attack.
