In late 2001 with the leaking of the normally heavily guarded Ants code which was used by Microsoft to create the Ocean map, several regular players began dissecting and analyzing the code, with the goal to create their own maps and eventually their own map packages. Soon, in early 2002, the code for map creation had been decoded and circulated among a few players. This resulted in an explosion of "homemade" maps and a release of the "Ants Map Wizard" by Ants player FCouples. Later, more Ants Map programs were created, including the Map Designer Program from Slayer. FCouples later improved his Map Maker, giving it better compilation facilities and larger map sizes, among other features.
