Ace Combat 3: Electrosphere/Missions (Japan)

Following is the list of missions in the uncut original version Ace Combat 3: Electrosphere. Upon its initial release, Electrosphere consisted of 52 missions but due to story branching, only 15 to 19 could be completed in a single playthrough. In addition to the "core" missions, there were 8 hidden bonus missions that replaced or were inserted between certain missions, usually as a result of the player's action in the previous missions. At four points, the player's choices determined, which story branch the game would proceed along, leading to one of five possible endings.

In the Mission Simulator mode, the missions are numbered hexadecimally.
