StarCraft beating

(tags game, real-time strategy, failure)

I'm playing single-player campaign StarCraft. I'm about 30% done, playing the Terran missions. All but the last Terran missions have given me no trouble. I basically try not to read the strategy guide before the mission, but if I fail, I go to the guide.

I haven't failed until now.

This last Terran mission, "Hammerfall", is something else though. It's hard. My StarCraft enthuiasm seems sapped now. Well I only failed two times but it takes a hour to get a result. Ugh.
