Game Boy Wars (ゲームボーイウォーズ?) is a turn-based war simulator produced by Nintendo that was released exclusively in Japan for Game Boy in 1990. It is a portable follow-up to 1988's Famicom Wars, making it the second game in what would be later known internationally as the Advance Wars series. A series of sequels to the original Game Boy Wars were later produced by Hudson Soft.
Two countries, Red Star and White Moon, are at war. The player takes control of either forces on hexagonal maps with square tiles. As the commander, the player must direct his or her forces to either destroy all of the enemy forces or capture the enemy's capital city. In pursuit of this goal, the player attempts to take control of the cities, factories, airports, and harbors on each map. There are a total of 36 maps in the game.
The player and their opponent (the CPU or another player) take turns (or phases) in moving their army, which can deploy up to 50 units. Each of the units can be given an order, such as attacking enemy units, assisting friendly units, or conquering. Units can be land, sea, or air units, and can be deployed from near the player's capital using funds obtained from any of the player's properties. Land units can be sent out from cities or factories, air units from airports, and vessels from harbors. There are 24 different kinds of units that can be deployed by both armies.
Game Boy Wars TURBO
An enhanced version of the original Game Boy Wars was produced by Hudson Soft and was released in 1998 under the name Game Boy Wars TURBO. The main new feature in this version is that the CPU now has a faster decision-making algorithm during its turns, allowing battles to proceed swifter than in the original. It also boasts 50 new maps, as well as support for the Super Game Boy.
