In this mission start off by getting numeras scv's to mine minerals and gas. As you are doing that put all of your marines into the bunkers. Make sure that you repair the bunker and vulture in the begining of the mission. Make a barracks and multiple marines, make sure you have about three bunkers loaded with marines at both of the way's into your base. Also make some missle turrents behind those bunkers. Make a factory and a Machine Shop. Upgrade the Vulture's spider mines first. (spider mines are mines that once planted become invisible to the enemy unless they have a detector, They will wait until they sense enemy units approaching then they will come up and go up to the enemy unit and explode. Be carfeful though they can kill your units when they explode.) Put these spider mines in front of your bunkers. Build and academy and upgrade marine attack range. keep repairing any bunkers, missle turrents, or vultures that get damaged in the zerg attack. Wait for thirty minutes and you will be just fine.
