The Conversion Pack is a comprehensive add-on to the original Battlefront II. It adds 25 new maps - including all of the maps from Battlefront 1 not originally featured in Battlefront 2, 5 new gamemodes, a new era, and a substantial amount of expanded unit content to the original game.
Kind of a must have mod in many ways, the old republic content could use a rework but this is truly a must have mod for SWBF2. It would be cool if the Battlefront 2 Remaster Project had a look at some of these maps and improved them.
