Abstract: A non-transitory computer readable recording medium has stored thereon instructions to be executed on a computer providing terminal devices with a battle game in which users each operate a unit. The instructions cause the computer to perform the steps of: determining a unit parameter of each of a plurality of units, group information being associated with each unit and indicating a group, among a plurality of groups, to which the unit belongs; deploying the units on a field, divided into regions, in the battle game; varying the unit parameter of a first unit on the field based on the group information associated with the first unit and the group information associated with a second unit on the field, the second unit having a predetermined positional relationship with the first unit; and conducting a battle between the first unit and other units using the varied unit parameter.

Abstract: A game program causes a computer to set, if it is determined that a point based on a first action of the character of each of an own player and another player is greater than or equal to a predetermined value, a specific period from a time when an instruction to input a second action has been first accepted from the own player or the other player as a cooperation accepting period, to accept the instruction to input the second action up to a maximum number of times set for each cooperation player from a cooperation player other than the player who has instructed input of the second action, among the own player and the other player, during the cooperation accepting period, and to vary an effect of the second action in accordance with the number of times of the instruction to input the second action.

Abstract: A non-transitory computer readable recording medium has stored thereon instructions to be executed on a computer providing terminal devices (12) with a battle game in which users each operate a unit. The instructions cause the computer to perform the steps of: determining a unit parameter of each of a plurality of units, group information being associated with each unit and indicating a group, among a plurality of groups, to which the unit belongs; deploying the units on a field (23), divided into regions, in the battle game; varying the unit parameter of a first unit on the field based on the group information associated with the first unit and the group information associated with a second unit on the field (23), the second unit having a predetermined positional relationship with the first unit; and conducting a battle between the first unit and other units using the varied unit parameter.
