Multiplayer maps for these games are easy to find, but single player is very difficult to find. This pack contains 61 missions for Generals and 134 missions for Zero Hour. Initially, this pack was found on ppmforums.com, but now it is impossible to download it, because all links on all sites lead to nonexistent files on gamefront. I have this pack left. I hope you find it useful.
Also, for the overall picture, I added skirmish maps (multiplayer maps that support bots), which are also harder to find than regular ones. Is 20 maps for Generals, 25 maps for Zero Hour and 6 maps specially optimized for Advanced AI Mod. I recommend visiting the author’s site: http://www.hogmark.com/generals/
