An information processing apparatus comprising a computer, an input device and a display providing a graphical user interface coupled to the computer, the computer configured to define a virtual space including a battle field of a battle game in response to inputs from the input device and to display the battle field on the display, the computer being further configured to execute instructions to perform operations comprising:

• set a plurality of player's groups each including at least one player's unit;
• place a player's unit included in a first player's group and an enemy unit on the battle field in the virtual space, the first player's group being among the plurality of player's groups;
• execute the battle game where at least one of battle units including the player's unit and the enemy unit are moved on the battle field, and the player's unit and the enemy unit are caused to battle against each other in accordance with a positional relationship on the battle field;
• and
• use a computer-implemented counter to count a number of elapsed turns or in-game time in the battle game, wherein
• if the number of elapsed turns or an in-game time the computer-implemented counter counts satisfies an update condition determined in advance in the battle game, perform a replacement process to erase all player's units placed on the battle field while maintaining a position of the enemy unit on the battle field, and place a player's unit included in a second player's group among the plurality of player's groups on the battle field, and
• the player's unit and the enemy unit after the replacement process are caused to battle against each other in accordance with the positional relationship on the battle field.
