Tank Battalion

Tank Battalion is a multi-directional shooter arcade game that was released by Namco in 1980. It was the only game from the company to use a Motorola M6502 microprocessor (run at 1 MHz), and did not do very well in the arcades given that it was out-shone by Namco's own Pac-Man. The game was ported to the MSX 8-bit computer under its original name, and was also later ported to the Japanese Famicom (with a corresponding Vs. System arcade game) and the Game Boy. Since new features like better animation and new variety (like different terrain, powerups and different types of tanks) was added, these versions were retitled Battle City. A sequel named Tank Force was released in 1991, which allowed up to four players to play simultaneously.
