Tokio

In the game, the player controls a red propeller-driven airplane, flying over the city of Tokyo.[2] He's able to shot and capture other red, smaller planes, which then will follow the player in formation. The player can choose between 3 formations: the first is able to shoot both air-to-air and air-to-ground projectiles, the second only air-to-air (but on a larger area), the third only air-to-ground (but on a larger area as well). During gameplay, the player should react accordingly to the threats and quickly decide which one of the 3 formation types is more adequate at one given moment.
