Building the base | Advices SC II: Legacy of the Void Guide
Last update: 11 May 2016
First of all, the economy. Train enough workers to fully use all resource fields near the base as fast as possible. Whenever you can, build another base and increase the productivity. Keep attention to the state of the workers and immediately send to work the ones that have no jobs. Avoid unnecessary expenses. If you don't plan to use some unit types, don't invest into their buildings and upgrades. Keep increasing the productivity, even if it means creating 60 and more workers. Such large group will provide you with enough resources to produce even the most expensive units.
Quickly spend the resources. Return to the main base frequently in order to spend the accumulated resources. If you can buy or build something, do it. Saving the resources is recommended only in case of large and expensive units, such as Terran battlecruisers. In other situations, it is better to have a group of marines ready to defend the base or few upgrades under development than few hundreds of minerals and gas waiting to be used.
Build barricades. There are no walls in the game, but pylons and photon cannons can replace them, especially if they are placed in two or three lines. It will block your exit from the base, but during the campaign you will be able to bypass that problem, for example with the ability of the Spear of Adun. Terrans can use supply depots for the same effect. Zergs do not have walls, but usually they won't need them.
Group the buildings. Despite the fact that you can use keyboard shortcuts, it is wise to keep similar production buildings next to each other. There is a chance that a single attack will leave you with no production buildings, but it is definitely easier to train units in four barracks when all four of them are near each other. The distance can be most easily determined using the screen. If you have three barracks and you can see all of them on the screen at once, then they are standing close enough to each other. However, if you don't want to or can't keep all production buildings next to each other, then group them all under one key in order to manage them more easily.
Use varied defense. The turrets have their advantages, but they won't be enough to protect any base. Units can quickly reach place that is endangered, but they can be too far away doing a critical moment. Because of that, it is a good idea to use both methods of protecting the base - position turrets and units in key points. It is also a good idea to keep a small group of units in the back, as reinforcements for the defenders.
Keep attention to the mining. If you are mining too little resources - build a new base. Too little gas - send more workers to the refinery. You used some resource fields - move part of the workers to other bases or build a new one. You cannot allow for a situation when more workers are producing resources than it is needed. By doing so you would be wasting them and you would obtain less resources, which can make the game harder or even lead you to a failure. Keep attention to it and to how many workers have no job. In a perfect situation, all workers are constantly busy.
Keep producing military units. It will be especially important in multiplayer mode, but also during the campaign you will be constantly threatened with loses. It is wise to replenish your units regularly, which will be easier and faster than building a whole army from scratch. Additionally, by constantly creating military units, you will reduce chances that the enemy will have more units than you. It doesn't matter if you have used all supplies. The units in the building queue will not be lost, they will wait for their turn while you will be able to concentrate on other matters.
