Im not sure. In GTA SA the missions where beolen up in to chapters whitch include: LS, Country side, SF, Desert, LV, then the end. This mods mission will also be broken up simeler but each chapter will not have as many missions. Liberty City Getaway chapters include 1987, 1988, 1989, 1990, 1991, and 1992. 1987 is just the begining first missions and 1992 is the introduction and how CJ's mom died.
1992 is just a vid of parts of the intro.
