Set in late UC 0089, Advanced Operation occupies that elusive and underused timeline gap between the Gundam ZZ TV series and the film Char’s Counterattack. You follow the crew of the Pegasus Kai class ship Il Nido as they clash with a force of Neo-Zeon remnants commanded by a hawkish Haman Karn loyalist named Gerald Sinclair. Sinclair’s mission is to hunt down the representative of a moderate Neo-Zeon faction that seeks to make peace with the Federation: the late Karn’s own younger sister, Serrana Karn. The game features original character designs by Haruhiko Mikimoto of Macross and Gundam 0080 fame.
