Wars (series)

The player takes the role of a Commanding Officer (CO) in an army, usually of a country called Red Star (changed to Orange Star following international releases). In Days of Ruin, it is replaced by a nation called Rubinelle (Laurentia in the European release). In the single-player campaign of the Advance Wars games, each level consists of a new map and opposing CO to defeat. Victory is achieved when all the opponent's units have been destroyed, their HQ is captured, or another victory condition has been met. COs take turns recruiting and commanding units on grid-based maps. Units available include infantry, tanks, artillery, bombers, and many other military units. Each turn, each unit may move around and/or perform an action, such as attacking or capturing a property. Certain actions, such as capturing, diving, or loading may only be performed at certain instances throughout the game.[3]

The original Famicom Wars game consists of two armies, Red Star (which became Orange Star in later international versions, possibly to avoid associations with Communism) and Blue Moon fighting over square grid-based maps. The two armies could either be controlled by human players, or a human player could play against an AI opponent.[4] The original Game Boy Wars games featured a system similar to Famicom Wars, except the grid was changed so that the grid squares acted more like hexagons; each square is adjacent to six other squares, instead of four. Game Boy Wars also features a different opposing army called White Moon. Otherwise, the rules remain identical, and only in Game Boy Wars 3 were unit levels and a new resource introduced.[5] Super Famicom Wars, the sequel to Famicom Wars, introduced Yellow Comet and Green Earth, bringing the number of armies playable at once to four. It returned to the basic square grid-based map style of the original game.[6]

The Advance Wars games introduced several new elements. The most notable is that COs now have special abilities called CO Powers that can affect the battle in different ways, giving the CO a temporary advantage over the other COs, such as providing allied units with increased firepower or causing damage to opposing units. Black Hole Rising introduced Super CO Powers, and Dual Strike introduced Tag CO Powers.[3][7] Conditions such as fog of war, rain, and snow affect the abilities of units to reveal the map and move around.[8] Days of Ruin removed many of the features added to previous Advance Wars games, greatly weakening CO Powers and reintroducing a unit level system.[9]
