Command & Conquer: Red Alert 2 is a real-time strategy video game by Westwood Pacific, which was released for Microsoft Windows on October 23, 2000 as the follow-up to Command & Conquer: Red Alert.
Every aspect of game-play in the game is based on the collection of money. In the game, money can be collected by several means.
The most common is using Miner trucks to gather Ore and/or Gems and transport them to a Refinery. A player can also gain a lasting income by capturing Oil derricks (neutral buildings that are present in some maps).
There also are two one-time sources of money for Allied and Soviet players, namely collecting random crates which are present in the map and selling off buildings which are controlled by the player.
Allied players have a third one-time sources of money using a spy to steal an enemy’s money.
The money is spent on constructing and repairing buildings and units.
In both cases one can start construction before having the full cost in one’s reserves, as construction pauses if one runs short of money.
