Grand Slam Baseball , released in 1987, is a 1-2 player baseball game for the Commodore 64. The game follows basic Major League Baseball rules and features two teams. Players can define their own teammates' names and positions, although individual players are identical with no unique stats.
Gameplay takes place from behind home plate, where players must aim to catch pitches thrown by opposing pitchers. The player's objective is to knock the ball out of the park or score runs by hitting it into the field. The game relies on the popularity of its star players at the time of release: Steve Garvey and Jose Canseco.
