Kidou Senshi Gundam: Gihren no Yabou - Zeon Dokuritsu Sensouden (機動戦士ガンダム：ギレンの野望ージオン独立戦争), translated as Mobile Suit Gundam: Gihren's Greed - War for Zeon Independence, is a strategy video game developed and published by Bandai in Japan. It is the third game in the Gihren's Greed strategy game series based on the Gundam franchise.
It is the first game in the series where battles are fought in 3D. It adds an updated map system and military system to a rewritten script, several new characters, an updated spying system and Mobile Suits from MSV. However, this installment omits the Zeta Gundam era conflicts featured in the previous game. As a result, the Principality of Zeon and the Earth Federation are the only factions featured in this entry.
After completion of the game with each team, an option to use them in "IF Mode" is unlocked. Each completion of the game increases the player's IF Level and more points to use in the mode. "IF Mode" allows the player to create their own team; choosing such options as a leader (or creating their own leader), their home base, which officers to start with, which technology group their faction is in and what units the player starts with. This also comes with a variety of Scenarios to play through, with preset IF modes.
