This StarCraft 2: Wings Of Liberty mission guide will cover ‘Belly of the Beast’ providing the objectives, achievements (Belly of the Beast, Unbreakable, One Shot, 50 Kills!) and a walkthrough of how I beat this mission on hard difficulty during my own play through to satisfy all these achievements. Belly of the Beast in StarCraft 2: Wings Of Liberty takes place after the mission Gates of Hell. Jim Raynor is faced with the decision of having to choose between going with either Tychus’ or Warfield’s plan to disrupt the Zerg defenses on Char. Of the two choices available at this point in the campaign of StarCraft 2: Wings Of Liberty, Belly of the Beast is chosen by going with Tychus’ option. The primary goal of this mission will be to detonate 3 charges at various points in the underground Nydus network keeping the Zerg from being able to use Nydus Worms in any of the final missions.
Belly of the Beast in StarCraft 2: Wings Of starts with me in control of 4 hero units; Jim Raynor in Marine armor, Tychus Findlay, Rory Swann (Hero Marauder) and Egon Stetmann (Hero Medic). Jim Raynor is given his ability right away as I approach a line of Zerg defenses. The Penetrator round does massive damage to everything in a straight line from Jim, and is directable to fire at any angle from his position. Using it from the cliff allows me to take out the whole group in one shot. I use the penetrator round on the next Spine Tower guarded by various Zerg.
Reaching the next ramp Tychus gets his grenade ability, which I place right on the cliff to take out almost all the units here. Up the ramp and around a bend lay more Spine Crawlers with Roach, ling and hydra guards, using another penetrator on the Spine Crawler to eliminate it off the bat, and switching to Tychus’ grenade ability to clear the units that rush my squad. Most of this mission is about using abilities at the right time.
Rory’s fire turret Flaming Betty is unlocked up ahead, and placing it where the game directs me works just as effectively as suggested, using a penetrator on the group as they cluster to clear them out a little quicker. Warfield radios in to rescue a nearby squad of trapped Dominion soldiers, which I divert my force to do so, as each extra unit is a major help here. A penetrator round hits the Abomination and Spine Crawler to hill the later while crippling the Abomination. A grenade from Tychus also helps to weaken the group of 4 Spine Crawlers here. Penetrator rounds from the cliffs takes out all but one, which I finish off up front to rescue the 4 Marines and single Medic.
My now larger group destroys a barrier and moves just past where it was, triggering an ambush of unborrowing Zerg from both sides. Holding position I hold them off pretty well. Next I reach a entrance to an open area of cavern so I place Flaming betty right in the opening where the Zerg on the other side see her and move to attack. This allows me to draw the Abomination and lings out, and attack them with my troops safely out of the way while Betty tanks damage.
After this encounter, reaching the ramp leading down to the first fissure location triggers a trio of Nydus Worms to erupt from the ground, spilling drones and an abomination out of them that head up the ramp to attack my forces. I place Flaming Betty at the top to stem the tide of attackers, and use a penetrator on the Abomination that attacks to drop its health quick. Pushing my way towards the worms with Betty’s help after taking the Abomination down allows me the end the worm’s existence and allows my passage to the first fissure.
Reaching the first fissure starts a new phase of the mission, where the task is to defend the planted charge from Zerg attack waves while on screen timer counts down from 2 minutes and thirty seconds. I set Flaming Betty up to the left entrance and group the non hero troops with their Medic to where the Heroes will help take fire for them. I use Jim’s penetrator rounds to quickly put down the series of Nydus Worms that come up from the ground at the 3 entrances. Flaming Betty has to be replaced every 45 seconds, as the turret eventually expires. Tychus’ Grenades also are useful in damaging large groups of Zerg. Once the timer reaches 0 the game goes to a cut scene where everyone dips out from this part of the underground cave network while the charge goes off.
In the second map for this mission, it’s time to make it to the next fissure again. The first group of units I encounter heading out from the starting position is a group of Infested Terrans with an Infestor. Flaming Betty is tasked to handle them with the rest of my squad working on this group with their normal weapons.
Moving south I encounter a massive group of infested packed in the cavern. This group falls to a penetrator round from Jim and one they get closer, a grenade from Tychus. Past this first large swarm of units lies an even more massive army of infested. This next group is going to be where I make my One Shot, Fifty Kills! achievement. This is better shown in the video walkthrough posted towards the end of this article.
I position Jim in a rocky area where I just cleared out the infested, with Stedman behind him and to the right. The rest of my troops move back and are set to their own control group. I take a single marine, stim him and run him south to trigger the army’s advance, which once they start moving, keep advancing onwards without a leash point to return to. I have the Marine run back to where the rest of my troops wait away from Jim, and take control of him to prepare for his shot. Once I have a full line of them under the penetrator rounds aim I let it rip, unlocking the achievement seconds afterwards. Now the achievement has unlocked, I quickly move in the full force of my troops to help Raynor, who is still kept healed with Stedmann’s help. A grenade from Tychus practically evaporates the whole bunch still attacking Jim.
Moving onwards to where the infested came from I have to clear some Spine Crawlers and after those, a single Abomination. After this first one, a second Abomination pops out of the ground, followed by a stream of Banelings hat pose a serious threat in this mission. Warfield radios in about another squad of trapped soldiers, 2 Firebats and a Medic who are under assault by Nydus Worms spewing troops. I take the time to save them, as Firebats are the anti-Zerg king. On the way into the creep filled cavern to rescue them, a group of Zerg attack from the rear, again including Banelings.
Up ahead is a winding cavern with Nydus Worms that are spilling a massive amount of troops that must be pushed back to kill the worms and reach the end of the area. Flaming Betty helps to stem the tides and I use penetrator rounds once I’m close enough to hit the worm ahead. Once I’m up to the second worm, I’m warned of flanking infested humans. Banelings, an Ultralisk and right after a flanking Abomination serve to keep the pressure up, but Betty makes a good rear guard.
Reaching the second fissure the game breaks into another cut scene before starting another two minute thirty second timer for defending the charge as it arms. The first waves come with mostly infested, although a few Banelings are mixed in. Placing Betty close by the lava pit helps in spades, giving her coverage over the bottom 2 paths, while I focus on an Abomination that comes from the top. Using the penetrator rounds like in the first defense, helps to quickly shut down Nydus Worms that spit out troops. At the 30 second mark, a pair of Ultralisk attack. One of them is preoccupied with Betty while I use abilities to take them both out.
The final fissure map comes up after another cut scene, much smaller than before. The encounters here come in the form of infestation sacs that explode and release several infested troops out of each. Flaming Betty is a great option in clearing these rooms. Past the first few rooms is an Omegalisk attacking a barrier to reach a group of Dominion Marines. I use a penetrator to knock down some of his health, and clear out the Spine Crawler and infested that attack me nearby before rushing to their full aid. I lose my Firebats but put down the Omegalisk and rescue the Marines to join my squad.
Setting the charge in the final room begins a cut scene where a Boss fight begins against the Zerg Queen. She focuses on popping the nearby egg sacs to release a slew of troops at me from each. I use my abilities as quickly as possible for pure damage, and to kill some surrounding infested while I’m at it. At first she focuses on the eggs, but she will attack when I either get too close or cause too much damage. Dropping her health by almost 25% causes her to disappear momentarily, coming back again in another egg chamber.
After attacking her in all 3 egg chambers, she is now down to 25% health. She pops up the 4th time near the charge gaining a 10% chunk of her health back, and unleashing a temporary stun attack on my squad. This attack has a wide area of effect and is difficult to avoid. She unleashes it a second time while I’m attacking her, killing a marine while my Medic is unable to heal properly. At this point she no longer disappears and we duke it out before I drop the big beasty after firing a penetrator and throwing a grenade for damage. This breaks the game into another charge detonation cut scene.
After the final charge is blown the lava starts rising and it’s time to mad dash it to the extraction point. This part requires a fast as possible approach, ignoring any smaller zerg that aren’t causing enough damage to hinder your progress. Saving a penetrator round for the pair of Spine Crawlers is beneficial while using grenades or Betty on groups of Zerg.
Anything else you can ignore, do so, because the lava rises pretty fast. One Abomination poses the last big obstacle, forcing me to penetrator round him to deal with him quickly, and reach the extraction beacon with seconds to spare and the lava hot on my tail. Reaching this beacon brings the mission Belly of the Beast to a close.
