This guide assumes that you went to Kaldir first, if you did not, some of the comments are invalid. I suggest going to Kaldir first to unlock the basic Zerg units (Roach & Hydralisk) for future missions, since they’re the foundation of most Zerg combat. However, you can choose to do Char first without any problem.
At this point in time you can now use the evolution chamber. The evolution chamber allows you to choose between one of three upgrades for each of your units. Go ahead and choose the upgrade for the Zergling that fits your playstyle.
Main Objective Reward: +5 Kerrigan levels
Bonus Objective Reward: +2 Kerrigan levels
New Unit: Roach
Roaches are ground only assault units, they should construct the front line for Hydralisks and any ranged attackers. They can burrow to regenerate.
WARNING: Flash Freeze - At random intervals your troops can be frozen, you can complete bonus missions to increase sight during the freeze and you will get immunity earlier on from the freezing effect. A timer at the top will display the timing.
First up is a short walk until the first flash freeze. Use Kinetic Charge to take out any beasts in your way. After the freeze you should gain some immunity to it, but you’ll probably be down your Zerglings. At this point just keep walking forward until you unlock your base.
Your build order should be to just max out your economy first and foremost. A Flash Freeze will come rather quickly and this will be your first chance to deal damage, you should be immune to the freezing effect and can pillage all of the Protoss you can in the time. My biggest suggestion is that since you have 1:30, you should focus on the first 60 seconds on attacking and retreat in the last 30 seconds. Although I retreated with about 10 seconds left the first sortie in order to take out the pylon.
I, personally, put a second hatchery up early on without realizing that you get an early expansion. You can put your second hatchery either in your main base or wait until you take the base to the north. Up to you, really, again you are the commander of your Protoss slaying forces. I threw up two extra hatcheries in the expansion, just so I can pump troops out, and queued up about 15 drones from the previous base since you get a free hatchery at the expansion.
Anyway, setup your expansion and just start pumping out units once your economy is up. You’re racing against the clock here, so you’ve got to put your all into it. Don’t neglect your defenses at your original base, the Protoss will attack there. You just need a few Spine Crawlers up to hold off any attackers until you can make your way back, at least until you push far forward.
After you take down the second spire, you can harvest from a third expansion. Obviously in higher difficulties, you should take advantage of it, but on Normal you shouldn’t even honestly bother. You can charge the second base before a flash freeze occurs, but the third base has several Colossus in it.
This is the easiest and can be assaulted directly during the first flash freeze and should be finished off by the second, you don’t need anything other than a few Roaches and a few Zerglings.
This base is a bit harder, you’ll want to start the assault about 15 seconds before a flash freeze (they only last 60 seconds by this point). Then just keep pushing.
Again, assault 15 seconds before the start of a Flash Freeze, you’ll lose some troops to a Colossus but that’s just life. When the freeze hits, break your troops up into teams to take out the Colossuses so that when it ends they don’t ruin your entire forces. After that just focus everything on the objectives
If you’re going for the 15 minutes or less, skip the bonus mission unless you absolutly need it. If not, split your forces off to take out the Matriarchs.
At this point you now have access to the Archives and the ability to alter Kerrigan’s abilities. These features are on the main screen.
