Ghost Squad (ゴースト・スカッド) is a 2004 light gun arcade game developed by Sega AM2 for the Sega Chihiro arcade board. It was released on the Nintendo Wii three years later, making use of the Wiimote as a light gun; in Japan, a version bundled with one, Ghost Squad Wii Zapper Doukoriban (ゴースト・スカッド Wiiザッパー 同梱版), was also released.
Players can purchase an IC card at some arcades, which is used to save unlockable items and scores.
An enhanced version of the game, Ghost Squad Evolution, was also released in 2007 in the arcades. It has additional weapons, costumes and difficulty levels, however the game is otherwise the same.
