In a game program for a multiplayer game, when a player character receives damage and the strength level reaches a certain level, the player character goes into an extension state before death, in which the character is weakened but is able to recover. If a friendly player character performs a recovery action within a certain time from the weakened state having been reached, the player character in the weakened state recovers to a normal state. On the other hand, if the player character in the weakened state is attacked by an enemy character, or if the certain time has elapsed, the player character in the weakened state is caused to die and the game is ended.
