Rockman EXE 4.5 Real Operation

Rockman.EXE 4.5 Real Operation (ロックマンエグゼ4.5 リアルオペレーション) is a spin-off game from the Mega Man Battle Network series that was released only in Japan for the Game Boy Advance. Players can control one of the many different NetNavis from previous Mega Man Battle Network games to compete in NetBattle tournaments. Characters include Rockman (MegaMan) himself and all of the other "Soul Unison" Navis from the fourth game of the series. A new Navi not included in the fourth game, Starman, is also available.

Gameplay
In Real Operation, the Game Boy Advance itself, in a sense, acts as a PET, allowing the player to control various NetNavis from previous games in the series. Players will engage in various tournaments, with a large variety of chips at their disposal that cause different effects on the enemy and battlefield. During tournaments, players can use Souls to assist them in battle.

Real Operation could also be used with the Battle Chip Gate, a Game Boy Advance accessory that allowed players to slot in real-life toy Battle Chips for use in the game, a feature that would be carried over to later games in the series. Users of Real Operation can also play multiplayer games against Mega Man Battle Network 4 users and other Real Operation users.
