Abstract: The objective of this invention is to provide a game machine and information storage medium that make it possible for players to perceive which player has succeeded in attacking which target, in a simple manner. When players have launched attacks against a target, attacking player identification information, which is information for identifying which player has succeeded in attacking that target, is associated with that target and is kept and saved. Targets 40-1 and 40-2 that have been hit by shots 32-1 and 32-2 from players 1 and 2 turn red and blue, which are symbolic colors for players 1 and 2, or change shape to symbolic shapes for players 1 and 2. If player 1, whose symbolic color is red, succeeds in attacking a target then player 2, whose symbolic color is blue, succeeds in attacking the same target, the color of the target first changes from a neutral color to red, then to blue.
