Missions consist of a turn-based strategic battlefield where the player directs echelons across a map consisting of linked nodes with the goal of fulfilling pre-determined mission requirements, such as capturing an enemy command node or rescuing hostage units. Players are able to deploy and move echelons during their turn by expending action points, which depend on the number of heliports controlled and the number of echelons deployed. The enemy units move during enemy turns based on preset instructions. If a player's echelon meets an enemy unit on the same node, a combat sequence is initiated. Combat is largely automated, but players can activate offensive and defensive skills specific to each T-Doll in real-time as well as move individual T-Dolls across a formation consisting of a 3×3 square grid. The position of T-Dolls within the echelon's starting formation provide stat enhancements to other T-Dolls, and the individual stats and abilities of the T-Dolls altogether determine the outcome of the battle against the enemy team. Some missions, known as night-time battles, will handicap the player with a limit to the number of turns possible as well as include a fog of war mechanic restricting visibility over the strategic map. A score based ranking map is unlocked at the end of every major in-game event, where players can compete for rewards based on their highest score relative to other players during the event.
