What's a mini? I was sort of not paying attention for parts of it. Fucked around and went Ultras and Banelings. Those respawning ultras are amazeballs. If I focused I'd probably be able to knock it out in 40. Honestly, I thought the WOL final mission was easier. Although, I only played that on hard. I just massed siege tanks around the base and used marines to deal with Kerrigan.
The mission archives thing in this game is AWESOME. You can replay any mission, on any difficulty, and fuck around with ANY upgrade or special ability. So sweet.
