When possible, place and upgrade a few Harvesters in order to produce raw materials. Maximize your storage capacity as soon as possible in order to make the most out of your resources. Spend 300 Crystals when starting the game to purchase a second Engineer Bay. This will allow you to build or upgrade two structures at once, which will save time. Obtaining a third Engineer Bay will help even more, but is cost prohibitive. Begin saving crystals during the time that you are exempt from player vs. player to purchase the resources for buildings, decreasing construction times, etc. Do not place your buildings too close together in order to avoid enemy splash damage. Create enough space for your troops and vehicles. Build and upgrade army structures to handle the proper amount of troops.
