In Tiberium Alliances, a base is where the player produces Tiberium, crystals, power, and credits. A base has a radius of 2 square units. Players can trade resources between their own bases at the cost of credits, depending on how far they are from each other. Bases appear as blue (if they are yours or your alliance's), green (ally's), white (non-aggression pact), orange (neutral), or red (enemy's). Secondary bases can be deployed through the research of an MCV. Bases are destroyed once their Construction Yards are destroyed in an attack.
