Armadillo Racing

Armadillo Racing (アルマジロレーシング, lit. Arumajiro Rēshingu) is a novelty racing arcade game that was released by Namco in 1996 only in Japan; it was the last game from the company to run on their System 22 hardware, and up to four players can play simultaneously when a pair of two-player cabinets are linked together. The players must use a trackball to take control of, like this game's title implies, an armadillo (red for Player 1, blue for Player 2, yellow for Player 3, and green for Player 4), and direct it through one of two different courses (the Shōgai Course, and the Sprint Course) - but they must also watch their armadillos' heart rates as they can have heart attacks if they get too high.
