I am really starting to hate this game, and I'm only 6 missions in. I tried 3 times to rescue the Norad II, and every time, the Zerg AI cheats. Honestly, how the hell is this supposed to be fair? You're up against an enemy that can control every one of its units at the same time, issue unique commands to every single one, AND use every unit more effectively than you can without even thinking about it.
The Zerg are supposed to be WEAKER than the Terran! How the fuck can 2 Mutalisks take out a missile turret, when the exact equivalent unit, a spore colony, can stand up to 8 FUCKING WRAITHS AT ONCE?
