Mission 1: Wasteland

Conditions for winning:

• Find Jim Raynor
• Build a Barracks
• Train 10 Marines
• Raynor must survive

Conditions for losing:

• All your buildings are destroyed
• Raynor dies

You gain control of some SCVs and Marines when you start the mission. You should group your Marines as Group 1 by highlighting them and pressing Ctrl+1. Now whenever you press 1 they will be automatically highlighted, and if you press 1 twice the screen will center on them. This is hotkeying.

Leave your SCVs for now and move your marines down southeast to where the base is. En route you will meet Jim Raynor in his Vulture. He is not likely to die with his high damage and 300 hit points. Include him in your group and go down to the base.

Then, move your SCVs down and start mining. You can kill some Zerg with your Marines and Jim Raynor if you want to, but it's not necessary. When you have enough money, build a Barracks and train 10 Marines. Once you do, the level's over. Zerg will not even attack during this whole level, so unless you purposely kill Jim Raynor, you're not about to lose.
