Starcraft II Heart of the Swarm Mission Guides Part One: Umoji Missions

Hop back in the saddle with Starcraft 2: Heart of the Swarm and our mission guides. Up first is the Umoji Missions (Lab Rat, Rendezvous, and Back in the Saddle), introducing basic gameplay concepts (base building, movement, unit creation) and setting the theme for the entire campaign.

StarCraft II Mission Guides


Welcome to the start of the Heart of the Swarm Campaign. After these first three missions, you'll have a choice in which missions you'll undertake from there. Our guides will walk you through the missions on Normal difficulty and provide advice on completing the various achievements. So let's get started!


This is the start of your journey, it teaches you basic base building and combat. There is no risk of failure in this mission.


Your first step is to select the drone, then build a hatchery. Then you’ll need to set the drones to harvest some minerals. It’s really easy so far and shouldn’t be all that difficult. Then build an Overlord, in order to increase your supply. No risk, nothing, take your time. At this time you can also build more drones, if you want, to increase your income, but do note you’ll need to make a spawning pool right after, which takes 200 minerals, but the extra drones helps in a little bit when you’ll need to spawn zerglings and overlords and there is a combat sequence up ahead, so you’ll definitely want to have an upper hand during it, if nothing else for ease of finishing the mission.

After the zerglings are made, you’ll be asked to destroy the Eradicator and have a bonus of releasing zerglings from pens. The zerglings from pens makes creating zerglings a joke, realistically, you shouldn’t need to make anymore, but it’s good to get in the habit of constantly refreshing your army.

As you move forward, you’ll run into a room with gas turrets, just attack move and you should be fine. The eradicator was a joke for me, honestly.

Lab Rat Achievements

  • Mighty Mouse: Destroy 35 Sentry Bots, you should completle this achievement with ease.
  • Rat Race: Complete the “Lab Rat” mission in less than 10 minutes, just work as fast as you can and skip unlocking the extra zerglings, keep making more at your base to save time.
  • Lab Rat: Complete “Lab Rat”
  • Mad Dash: Destroy 3 factiories within 10 minutes on Hard. Just keep making zerglings, non-stop, and have a strong economy ASAP to keep producing them.

Back in the Saddle


    1. Back in the Saddle:  Complete the Mission
    2. Full Throttle: Prevent the Dominion from Destroying the Tram Engine during the Tram Ride in the “Back in the Saddle “ Mission
    3. Brutal Legend: Don’t take damage from the Archangel in the “Back in the Saddle” mission on Normal difficulty.
    4. Nick of Time: Complete “Back in the Saddle” with more than 40 seconds on each lockdown  on hard difficulty.


Escape the Sublevel

First up is teaching you now to use hero abilities, the first one being Kinetic Blast. Press Q and click the Marauder, at which point you’ll be jumped by a couple of units, just focus them down and you should be good to go. Continue moving forward and you’ll reach some Marines in trouble, use Kinetic Blast to take out a ghost and focus the units down. There is a recovery console up ahead, so any energy used won’t matter, realistically.

Crushing Grip is the next skill you’ll learn to use. It’s important to pay attention to how these abilities are used, since you’ll be using them a lot in upcoming missions. Continue on, there are a few ambushes but nothing you can’t really handle. You’ll reach a room where you’ll be locked in and a door will open with zerglings rushing at you.

In the next area, you’ll be tasked with moving to a set of doors while a timer runs. Ignore the time, use Kinetic Blast on the upcoming Firebat, and then be a little bit more suave with the choke point. Let the Firebat live so it’ll mow down the zerglings and use Crushing Grip to finish off the entire group near the end.

You’ll move through another two sets of doors, rather easy stuff along the way. Use your abilities and it shouldn’t be an issue. You’ll come to a room where you’ll have to make a choice: gas the room or release the zerg. Personally, I released the zerg to deal with the mechanical units, but the choice is up to you. Remember, you’re the master of your own dominion slaying rampage.

Defend the Tram Engines

This part can be easy, if you’re alert. You have two restoration terminals, so using your abilities shouldn’t ever be an issue, and an assortment of defenders. Watch your mini map for incoming and use Kinitic Blast liberally. I like to use it on the Medivacs because it gets rid of the passengers. You’ll eventually run into a Siege Tank but it was hilariously easy to beat down. The recovery terminals heal your allies, so it’s all good there.

Reach the Spaceport

You’ll move forward and eventually have to fight Archangel. This is where the game gets hard – if you want the achievement. You can’t take any damage from the Archangel, so it all depends on how much patience you have.  In the air it’ll draw a line on the ground and charge forward, bombing the area. On the ground it’ll put targets on the ground and you’ll need to dodge them. If you’re alert and don’t ever really get greedy, you should have the achievement no problem.

Achievement Recap

  • Full Throttle: Follow the guide above, it’s really hard to let a tram engine die on normal. Just watch for incoming and take them out.
  • Brutal Legend: Watch out for the arrows on the ground and don’t stand in them, use your restorations to try and keep your allied heroes alive.
  • Nick of Time: Play through on normal first to get a hang of where everything is and it all just boils down to micro.

Previous Mission: LAB RAT | Next Mission: RENDEZVOUS

StarCraft II Mission Guides


This is when you finally get to manage your own base and attack. The key to victory on this map is a strong economy mixed with a constant stream of zerglings and Swarm Queens. Swarm Queens can walk on land or creep t the same speed, that's their sort of special ability.


Hold Out for Reinforcements

The first thing you need is a spawning pool, not! Build more drones. Always build more drones. Get your income first, that’s so critical in this game. Your base is pretty well defended with Spine Crawlers, so you’re going to want to get setup for a long fight. Go ahead and build the spawning pool and start working on building a nice supply of zerglings and a Spawn Queen.

The goal here is to get the two achievements done ASAP, before the 15 minute timer runs out. To that end, get a strong economy up and build zerglings, move out and start working on the objectives. I sent a suicide force out to snag the two mineral patches on the right (and build a second hatchery), but again you are the captain of your dominion rampaging, so it’s all up to you on how you want to proceed.

I was able to do it with about five minutes left, simply making sure I had at least 20 to 21 drones up, using Kerrigan to push objectives, and just spamming zerglings. The Spawn Queens are a good choice to; you should build plenty of those. They’re meatier and don’t die to the

Anyway the mission progresses as follows, you’ll have 15 minutes and you’ll be alerted at various intervals of different caves that you can rescue units from. The best thing is to sort of get some momentum going, make a strong economy first then start expanding hatcheries. There are various minerals residing over the map, so those can help you get at least two extra hatcheries up. Once your economy is stable, start producing Zerglings and Swarm Queens. Swarm Queens are great for dealing with the new  Hellbat unit while Zerglings can just swarm everything. Your base sort of defends itself, only leave a few defenders back and bring Kerrigan with you on all assaults.

The right most cave is the easiest, especially with Kerrigan. The next cave on the left is easy too, but the third cave has an entire base around it. The easiest approach is from the right side, you can focus down the cave guardians to unleash the brood and help gain momentum is taking the actual base.

As for getting fifteen buildings, you can focus on the main encampment to the northwest or there is a slightly easier camp on the east that you can assault. Either way, fifteen buildings can go down fast.

After the fifteen minutes are up, you’ll be presented with an entire swarm, press F2 then attack click the cannon. Afterward the mission then completes and you can either move on to the Charr Missions or the Kaldir Missions. I choose Kaldir because I want the extra unlocks before moving to Charr.
