Main Objective  |  Gather a large army (100)

At the start of the mission, your goal is to simply amass a sizable army. You'll be attacked occasionally as you build, but you've got plenty of time to focus on recruting. Add a reactor to your barracks so you can pump out marines and medics and we also suggest building a second barracks so you can add a tech lab and train marauders. Man the already-established turrets with marines and consider building more turrets for simple defense. There are some supply caches within the base that you should collect to build up your resources early.

Soon, you'll get word of a friendly drop pod crash landing nearby. If you can get to the stranded marines before the zerg do, you'll add them to your ranks and also get access to some supply caches that came down with whatever ship they crashed in. Take a healthy group of units north to save the lot, then return to base. There are ten drop pods that'll land throughout the mission. Be ready with a sizable force that you can move around while also leaving some defenders at the base. The drop pods will be marked on your map as long as the stranded units are still alive. Be quick about saving them 'cause they won't last long.

The third drop pod will net you a trio of vulture cycles and access to a factory. Don't leave the factory there! Launch it into the air and land the factory in the middle of your base. If you allow the factory to remain stranded, it'll soon be overwhelmed by zerg. Later, you'll get the chance to rescue some aerial vehicles and an accompanying starport to the southwest. Again, if you like the idea of the starport sticking around you'll want to launch it from its resting place and move it into your base.

Main Objective  |  Destroy the nydus worms (3)

Things get a bit crazier when you reach the required army size. You get introduced to an ally base at the far east end of the map. It's got three nydus worms outside that you need to destroy, but getting there will require much work. From your base, take a massive crew (still leaving some behind to play defense) southeastward. The path to the nydus worms winds through some heavily-infested zerg territory so make sure you're armed with plenty of medics to keep your crew alive. Honestly, we found aerial units a bit helpless. An army made of marines, marauders and medics seems best for tearing through the lot. Target dangerous enemies like spine crawlers and brood lords first before bothering with lesser enemies.

An Achievement for the mission, "The Big Bang Cannon," challenges you to destroy all six spore cannons in the mission. You likely won't run into all of the spore cannons—stationary, spewing gross things—by chance so we've got screenshots below showing each of their locations. Note the mini-map marker that indicates where on the map the view in each shot takes place.

All three of the nydus worms are in close proximity to each other. Destroy all three to end the mission.
