Command & Conquer: Red Alert 3/Base Construction

Allies
The Allies use a traditional build system. When a building is selected to be built at the ConYard, it is built up over time and then when deployed, it is instantly ready to use. They do not give ground control however, so you will need to expand your base by relocating your MCV or deploying Prospecters into Command Hubs.

Soviets
The Soviets build up their structures on the map. While being built they are unusable yet vulnerable. When finished they can expand ground control. The Soviets can also build a Crusher Crane to unlock a second build que.

Empire
The Empire's build system is very unique. Structures come out in the form of Nanocores, which can traverse both land and water. They can unpack into structures anywhere on the map. This system is good for grabbing Ore Nodes quickly. The Nanocores are vunerable to attack however, so escort them with Tsunami Tanks and Mecha Tengus.
