Doubling
From Populous Wiki
Please rewrite it to use a more formal, encyclopedic tone.
Doubling is the term which players use when two players, usually ones self and one's ally attack an enemy player at one time. Doubling can be used to a players advantage since one team can attack the attacking players bases while they are doubling your ally. Professional players will make a good defence in their base before they decide to double their opponent. This strategy is used many levels like Pressure_Point and Face_Off to either finish a player off at the end of the game or to damage their opponent at the start of the game to give them the upper edge in the game.
Doubling is a strategy and should be taken as so, It isn't against any rules as long all players decided to allow before/during the game.
