Rolling Thunder 2 (ローリングサンダー2) is an arcade game by Namco released in 1990. It is the sequel to 1986's Rolling Thunder and retains the same run and gun gameplay of its predecessor, adding cooperative gameplay for 2-Players and improved graphics. Unlike the original Rolling Thunder, which was set in the 1960s, Rolling Thunder 2 features a more contemporary setting to go along with its more futuristic designs. A Mega Drive port was released in 1991. Both, the coin-op game and the Mega Drive version, were released for the Wii Virtual Console.
