You mean the Extra Edition? It takes place between the Fairy Dance arc and the Phantom Bullet arc. It's silly to name arcs after games, seeing as ALO is present in most arcs, though not always the center stage for the story. If you want more specifics, there's a timeline on this wiki which documents the exact date of the arcs and side stories.
