StarCraft/Terran mission 1: Wasteland

It's been a while coming, but here's your first real mission. All your units start in the upper-left corner, and your base lies in the lower-right corner. Group the marines and hotkey them to 1; do the same with the SCVs and hotkey them as 2. Send them southeast, marines first, and kill any Zerglings you come across.

Going south, you'll meet Raynor. Take the entire group down to your base, then have the SCVs mine minerals while you build some more. Build a Barracks and just start training Marines. If any Zerglings attack, your marines can hold them at bay. Once you have 10, you win! (Didn't think it'd be hard, did you?)
