Last update: 11 May 2016
Like in Wings of Liberty, also in Heart of the Swarm you will be able to access your base from which to explore the area. Onboard of the base, you will be able to develop your units and heroes. Additional information, concerning the units available to you and to the enemy, as well as the Zerg technology tree , can be Accessed by pressing "F12" key during the mission.
Relatively early in the campaign mode, you will unlock the Zerg spaceship Leviathan, onboard of which, you will find a number of interesting locations. The first one to discuss here is the evolution chamber that allows you to pick one mutation available for each unit which, in turn, will completely alter the unit's capabilities. For example, Zerglings may use :the reinforced carapace that gives additional health points, adrenaline rage that increases the frequency of delivering an attack, or increased metabolism which allows for quicker relocation of units around the map. Apart from minor exceptions, (zerglings, mutalisks), I leave it for you to decide about the choice of capabilities, as it has no considerable bearing on the strategy.
Apart from that, after you complete certain missions, you will be given the opportunity to choose the right path of evolution for your charges. This can also be activated while in the evolution chamber, by pressing the Evolution Missions button. This will transfer you onto the surface of planets, where you will be learn about the superiority of one unit over another. Again, the choice you make has no bearing on the strategies described in this guide. It simply gives you the opportunity to work out your own solutions which may be even more effective.
In the course of completing missions, also your character will be gaining strength. The Kerrigan tab, which is available while you are onboard of Leviathan,, you will be able to chose individual special abilities before you start the actual mission. It is a good idea to experiment with those a bit, it is possible that you will define your favorite combination this way. In case you have any problems completing a mission, or obtaining an achievement, some mission shave an ability specified, which will make things easier.
