Uhm...everyone does know that the maps used in this release were indeed left over from an abandonded new Painkiller sequel. They most definitely will not have the polish that a planned and budgeted release would have...People Can Fly (PCF) and JoWooD have made this clear. Instead of never seeing them JoWooD...as a favor to People Can Fly and Painkiller fans...decided to let PCF finalize these maps and release them.
$5 is next to nothing by today's standards. Even a 10 year old can earn $5 in an hour or less...PCF probably spent 4 months or more on these maps.
